This site is established to provide Frederick County land owners
with information on efforts to stop the GYPSY MOTH from devastating our
forests. We will highlight the efforts of a local task force established
by Mike Kay, Maryland Forestry, to provide spraying to eliminate the Gypsy Moth.
Interested parties may come to this site to obtain current information
on this effort.
We encourage land owners to become involved with this team and provide
assistance if you would like.
Please visit our Contacts page for assistance.
We finally finished our spray program this morning at 7:45 am! Just in time,
as our Commander in Chief is visiting Camp David this weekend so we would have
to stop at least until Tuesday.
It appears to me that most gypsy moth are in their 3 to 4th instar so remaining
larvae will be around until about mid-June then they will pupate. In the next
couple of weeks we will se how effective our spraying has been since the larvae
are at the stage when they start devouring leaves. Let's keep our fingers crossed.
At this point in time we should continue to point landowners inquiring about spraying
to Ag-Air directly or another applicator. People that would like to spray can reach
Ed Cunningham directly at 717-487-4921.
I would like to prepare a report on this program and its effectiveness. Tom Lupp
mentioned that he would do a fly over to assess defoliation in a month or so. We
could use this information as part of the report. I also remember that the task
force was contemplating a follow up meeting to discuss this program. How about
sometime in July when we have a good idea of the results?
Finally, I would like to relay my sincere gratitude to Ag-Air and Parkton Woodland
Services for their insights, patience as we developed the program, and assistance
they provided during the administration of the program and the spraying. To Tom
Lupp and Lee Venables of the MD Department of Agriculture for their insights, and
especially for guiding me (actually doing most of the work with the Arc View and
Ag-Nav), to the Frederick County Commissioners who showed enough faith in our
efforts to provide 40% funding for the program which made it very cost effective
for most individuals.(We saw a large spike in registration after the 40% funding
was announced so this funding contributed to thousands of additional acres being
sprayed. To the Frederick County Forestry Board for their guidance and support
when we were developing the initial idea of the program. To Karen Gardner of the
Frederick News Post who covered the development of this program and whose efforts
helped spread the word that our supplemental program was out there. For those
landowners who helped coordinate spray blocks especially the Gypsy Moth Task Force.
These individuals helped get the word out, assisted with the development of the
program in a major way, coordinated spray blocks, and approached our elected
officials about the problem and our unique solution. And finally I would like
to thank the landowners who actually paid for the spraying. It is all of your
collective sense of Stewardship that helped save our forests from the
destructive nature of gypsy moth.
Thanks.
Mike Kay.
We started bright and early today but had to shut down around 8:45 because of
the windy conditions. Fortunately we were able to complete the remainder of the
South Mountain spray block and those properties in the Smithsburg spray block on
Loy Wolfe, John Cline, and Wolfsville Roads. Now, all that is left are a few
properties along Mink Farm and Tower Roads. We're hopping to complete them this
afternoon or tomorrow morning.
I was able to stop by and check four properties along Gambrill Park Road and Rum
Springs Road as per the results of the spray. I witnessed the same general results
as the other spray blocks in that there were numerous gypsy moth under the leaves
right about where I last saw them about 10 days ago. The only difference was that
they were now dead and dried up. I did not see any living moths on tree trunks but
found a few living moths feeding on ground foliage. The trees look very full and
lush although it appears that some trees have not fully leafed out yet.
Bill stopped down at Stronghold (Sugarloaf Mountain Spray block) yesterday to
view the results and noticed much of the same.
Hopefully, my next message will say that we are finished.
We were able to finish all of the Sabillasville spray block this morning
by 9:30 am and shut down when the winds began to increase. That leaves a few
properties on Mink Farm and Tower Roads along with the South Mountain spray
blocks north of Rt 40. We should be able to finish these with one more
spraying session, probably tomorrow morning.
!!! Halleluiah !!!
We assembled at the landing zone this morning and were greeted with high winds.
The winds were not diminishing so we called it quits for now. If the winds die
down we may attempt some spraying later in the day but the threat of oncoming
rain is a factor also. If we can't spray today it may be mid-week before we
can resume due to rain. We estimate that we can wrap this up in 2 days given
favorable conditions.
We continue to get calls from folks who would like to be sprayed. At this stage
of the program they need to contact Ag-Air directly at 717-792-1776 or they can
receive a listing of spray contractors by searching the MDA's web site.

We were able to start and finish the Emmitsburg spay block this morning and
concluded about 10:00 in anticipation of the upcoming rain. What is left are the
properties around Mink Farm/Tower/Catoctin Hollow Roads, and most of the spray
blocks in the area with a Sabillasville and Smithsburg zip code. We will assess
the weather conditions and hope against hope complete the spraying
by the end of the weekend.
I spent some time reading up on Confirm and read that it could take up to 10 days
for the moths to die once they ingest it. They should stop eating soon after taking
it in though so it may not be unusual to have them hanging around on the leaves, not
eating until their number is up.
Plans are being made to conduct post spray site visits next week to assess the
success of the insecticide.
Yesterday afternoon we moved up to Thurmont. Yesterday we were able to
spray all of the properties in the Lewistown spray block, all of the properties
in the Thurmont area east of 15, the properties associated with Otter Valley
spray block and the Petersen spray block.
Today has been a fantastic day for spraying weather wise and we were able to
spray all morning. We are now taking a well deserved break and will start up
again around dinner time. During our morning session we were able to spray most
spray blocks in the Thurmont region except for those properties around
Mink Farm and Tower Roads.
I have received a number of inquiries on what to look for to ensure that the chemical
is working. I will try to get back to everybody soon but duty calls and I got
to head up to Thurmont. One thought though, I read that the larvae should stop
eating almost immediately after being exposed to the chemical and it should take
2-3 days for them to die. My advice is to "let the insecticide work". You should
look at the condition of your trees from a distance. If they have a full canopy
today and it remains full tomorrow and subsequent days then the insecticide is
working. Try looking up into the tree crown "where most of the chemical was
deposited. Is it full? Just because some insects are active on a small tree or
the lower limbs may not indicate a failure for the Confirm to work.
We made it through the latest deluge and began our spraying again this morning.
We had a productive spray session and were able to complete the remainder of spray
blocks on the Gambrill Park Road area, the remainder of the Frederick Watershed
spray blocks, and those blocks on South Mountain south of Rt. 40. The contractors
are gathering up their equipment and moving up to Thurmont.
We will begin spraying in Thurmont after we have set up and when the weather
conditions dictate. We can not spray in the P-40 zone today, but are cleared
for flying in this area on Wednesday.
I ran into Amy Onken a specialist in gypsy moth control with the US Forest Service
today up on Gambrill Park Road. Besides helping to coordinate spraying Amy was
taking samples of the gypsy moth and she said that the moths are in their ideal
growth phase to be impacted by spraying so we are spraying at the best possible
time to impact these little devils. Amy also said that they are detecting spores
of the natural bacterium that impacts moths and she thinks we will have this going
in our favor, especially after the cool rainy conditions we experienced.
I have been receiving inquires about the current heavy rains impact on the effectiveness
of the chemical we have been spraying and can only say that we are confident that we
have sprayed all properties within the 4 hour time frame we are using as our ideal.
I posed this question to Amy and she was not certain what impact the heavy rains may
have. I stopped by a few spray blocks on Gambrill Park Road and looked at the leaves
and noticed that some dead gypsy moth were hanging on to the underside of the leaf.
They were dried up and obviously dead. When I shook the leaf the moth's dropped off.
I asked some of the Gambrill Park Road residents to monitor for gypsy moth and let me
know if there is renewed activity in the spray zones. By activity I mean that the
moths are crawling around and visibly chewing on the leaves.
I stopped by the Post Office and got a handful of the one cent stamps. I don't know
about you, but I am glad that stamps now are self adhesive and you don't have to lick them.
We had a brief window of dry weather this weekend that was utilized to
complete some more spraying. On Saturday afternoon we sprayed the Fox Road
spray block and those properties around Mountaindale. (Judging by the amount
of house parties I saw I'd say those Mountaindale people know how to have a
good time.) On Sunday we sprayed sections of Gambrill Park Road (Up to the
5-Forks area) We had to stop here when the winds kicked up. Then we worked
on Frederick City Watershed blocks. We shut down about 10:30 am so as to
provide plenty of drying time before the rains came again.
We expect to start up again on Tuesday morning and will finish our work on the
Frederick City watershed and Gambrill Park Road." In likelihood we will then
move back to Middletown and spray those remaining spray blocks on South Mountain.
From there we will move up to Thurmont so as to complete the Thurmont,
Sabillasville, Emmitsburg, Smithsburg spray blocks. Let's hope for good weather
so we can complete this by the weekend!
It appears that all of the oak leaves are 50% or larger throughout the county so
this should not hinder our progress.
Given the high winds and impending rain, we decided not to spray
Wednesday evening. It looks like Thursday and Friday will be washouts.
We might be able to resume on Friday evening or Saturday.
We will begin again on Fox Road.
I took a tour of the county yesterday to check oak leaf expansion and noted
the following: (Keep in mind that we should wait for 50% or larger
expansion before spraying.)
Etzler Road - 80%
Fox Road - 80%
Gambrill Park Road - 20%
Mink Farm Road (Thurmont) - 30%
Pleasant Walk Road - (South Mountain Myersville) - 30%
John Cline Road - (Smithsburg) - 30%
Mountaindale Road - (Lewistown) - 60%
Rt 77 Thurmont - 30%
Eylers Valley - Flint Road (Sabillasville) - 30%
Hopefully the rain will promote leaf expansion so when we resume the
county will have overall acceptable leaf expansion.
We were able to spray most of the lower South Mountain spray block last night
but missed John Brognard's block due to some glitch in the Ag-Nav file. (Sorry John).
We will return soon to finish this area.
We finished the Etzler Road spray block today but had to shut down around 9:00
am again, due to falling Rh values.
We hope to begin and hopefully finish the Fox Road spray block this evening
assuming that Rh cooperates and rain is not eminent. (Our rule of thumb is
that we need to have 4 hours of drying before rain comes otherwise the spay was
not effective.) We will not spray in the evening if we think that it will
rain later during the night because the spray might not dry.
We have pared down to one helicopter due to the relative lack of work.
i.e. (Only being able to spray 3 to 4 hours per day and that leaf expansion is
not ideal in the higher elevations or northern sections of the county.) We plan
to activate the second helicopter next week when leaf expansion should be ideal.
We are hoping to have all of the southern and central parts of the county finished
by weeks end, then we will bump up to Thurmont. The weather and possible
complications to the P-40 zone i.e. (The zone expands to a 10 mile radius from
Thurs-Sunday if any dignitaries are visiting Camp David over the weekend.) could
curtail our work until Monday.
We are very confident that the spraying should be complete by the end of next week.
We were able to finish the Urbana/Sugarloaf Mountain spray blocks and
moved to the Middletown spray block this morning. The Rh dipped below 60
so we had to suspend the spray operations. If the Rh climbs above 60 this
evening we will continue spraying in the evening, if not we will start
here first thing Wednesday morning.
Once we finish Middletown we will move to the Etzler/Fox Road spray blocks.
If we finish Middletown tonight we should be able to begin at Etzler/Fox
Roads at daybreak. (6:00 am) If we can not we will probably begin here
around 8:00 am tomorrow.
The forecast calls for rain on Thursday night and possibly on Friday.
I just spoke to Bill Bond and he informed me that they were able to
spray yesterday afternoon until dark and was able to complete another
200 acres in the Urbana/Sugarloaf Mountain spray block. We anticipate
a full day of spraying today and will probably have the block done by
the end of the day.
Day one saw us tweaking the Ag-Nav system and the relative humidity
plummeted from a reading of 75 to 35 right about 9:00 am. As such we had
to cut our day short . ( We can not spray once the Rh goes below 60 because
the spray will evaporate before it reaches the leaves.) The navigation
system is working perfectly now and Tuesday promises to be a good spray day
so that we anticipate spraying for most of the day. Wednesday should be a good
day as well along with most of Thursday. Rain is expected for late Thursday
and most of Friday.
As of 6:00 am today 5-5-08 we began our spray program! We
are concentrating our efforts in the Urbana and Sugarloaf Mountain
spray blocks for the next couple of days then we plan to move to
Middletown and Etzler Roads once leaf expansion is in the targeted
range of 50/60%. The warmer weather should speed up leaf expansion.
Ag-Air has all of the Ag-Nav files and they work in their system. Barring
any last minute revisions we are good to go. There are still a few properties
that still have not paid for spraying. These properties will be dropped from
our program at Parkton's request.
Ag-Air and Parkton met to calibrate the helicopters and everything went smoothly.
The spray monitoring crew met to discuss our monitoring techniques,
communications and other issues.
Ag-Air has purchased all of the insecticide and they have identified
all of their landing zones.
Plans are, to begin spraying on Monday, May 5, 2008. Assuming that the
weather cooperates and we have proper leaf expansion as determined by a
site visit on Saturday May 3, 2008. We will begin our spraying in the
southern part of the county with one helicopter working in the Urbana,
Buckeystown area while the other will work in the Middletown area. Once
these blocks are completed we will move northward to Myersville and
Etzler-Fox Road areas, etc. We hope to have everything completed by
May 16, 2008 or sooner.
We are not taking anymore applications. Anybody who wishes to have their
property sprayed should call Ag-Air directly at 717-792-1776 or search the
MDA's Web Site for a spray contractor.
Many people have called to say that gypsy moth are hatching now. I have
seen them also, but noticed some egg masses in the higher elevations on the
Frederick City Watershed on 4-25-08 and the Sabillasville area on 4-26-08
that have not yet hatched.
Once hatched, the gypsy moth are in their 1st development phase known as
an "instar". In this phase the moth spins a silk thread and disperses by
floating through the wind "ballooning". This spinning of silk was what
prompted its introduction into this country in the first place. The moth
does not start feeding on leaves until it reaches its second instar when
they initiate their "shot hole" feeding pattern when they make little holes
in the leaves. In their early instars gypsy moth are discriminating in what
they feed upon preferring the oaks, basswood, willow, and apple trees.
As they develop into their later instars 3rd, 4th, 5th the moths grow much
larger getting to be nearly 3 inches in length and they begin feeding on
the whole leaf . The moth become less choosy in what they will feed upon
and the will defoliate most trees except for certain varieties like ash
and tulip poplar. This is when severe defoliation takes place.
In our program we are waiting for most moths to be in their second instar
(when they begin feeding on leaves) and for the oak leaves to be at least
60% developed (to provide a surface for they spray to adhere to) before we
begin our program. This should occur around the first week of May in most
areas. We are checking daily with the Maryland Department of Agriculture
for the optimum time to begin and will do so once conditions are favorable.
If we spray too early we run the risk that more spray reaches the ground
instead of sticking to leaves where it will do the most good. Also, since
the spray has a active life of about a month; spraying too early may not
control large gypsy moth that could migrate onto your property from untreated
areas later in the month.
We are fortunate that our contractor, Ag-Air is beginning their program in
Frederick County and they are utilizing two helicopters. As such, once we
are good to go, we should get our spraying wrapped up in a week or two
depending on the weather.
One of the benefits of the chemical we are using "Confirm" is that the
moths quit eating immediately once they ingest the insecticide and they
often die within a day or so. As such, once sprayed you should see an
immediate response to the spray.
We have finished the mapping of properties and the information has been
converted to Ag-Nav files and are in the possession of the spray contractor.
As such, I can not alter the information or map out any new properties.
If someone has still not signed up they can contact Ag-Air directly at
717-792-1776 or they can search the MD Department of Agriculture's web
site www.mda.state.md.us/plants.gypsymoth for a list of spray contractors.
Did you notice that we're having a damp, cool spring? (Ok some days were warm!)
Given these conditions it is likely that the naturally occurring bacterium
and virus could become active and help us in our suppression efforts.
Hopefully we'll deal the moth a fatal one-two punch and really stifle
their populations so next year won't be as bad.
1. We have finished the final digitizing of spray blocks and submitted the
files to MDA for conversion and transfer to Ag-Nav files. I am awaiting the
return of the Ag-Nav files and once I receive them I will send them to Ag-Air
and they should have everything they need. I would like to thank Tom Lupp and
Lee Venables for their assistance with this process. Especially Tom, who
took precious time out of his schedule and literally did most of the work
on this process. Without Tom's help I don't think it would have been completed.
2. We are making last minute calls to landowners who have not paid the balance
of their fee. If they do not pay soon. We will exclude them from the spray
blocks. (I don't want to do this for many reasons, the main one being it will
mean extra work on my part; however, there are nearly 600 acres in this category
and it would be unfair to Ag-Air to spray these for free.)
3. Ag-Air purchased the Confirm and Penetrator Plus chemicals and is in the
process of identifying Landing Zones.
4. Many of you have e-mailed or called indicating that the gypsy moth are hatching
out. From what I gather, we need most moths to be in their second instar and for
the oak leaves to be 60% or more developed before spraying begins to ensure that
we hit the main hatching of insects, and that there is plenty of surface area
on the canopy for the chemical to adhere to. Otherwise the chemical falls to
the ground and does no good. With all this in mind we are anticipating beginning
the program sometime during the first of the month.
5. We have a total of 8,200 acres that have paid; and another 600 that say they
will, totaling 8,800 acres.
6. We will be starting out with two helicopters and we can expect to spray about
1,000 acres per day per helicopter on a good day so if all goes well, the
spraying should be done in one week.
7. Tom suggested that we utilize the Web Site to indicate where we will be
spraying on any given day. Perhaps John and I can coordinate this.
I will work with Mike to provide daily updates. - John
Many people attended the County Commissioners workshop on the gypsy moth
problem yesterday providing testimony on why the insect is so destructive
and lending support for the regular program administered by the Maryland
Department of Agriculture along with our supplemental program. We were
rewarded for our efforts when the Commissioners voted to fully fund the
Department of Agriculture's program anticipated to be 20,000 acres and
to provide 40% funding up to a maximum of $150,000 for our supplemental
program. The $150,000 total was derived from our estimate that we will
treat 10,000 acres with the supplemental program. If more than 10,000
acres is treated the cost share percent that landowners receive may be
less than 40%. The gypsy moth task force will be meeting soon to
determine how these funds will be distributed.
We would like to thank the County Commissioners for their dedication to our
forests and natural resources. Thank you very much!
Please visit our Contacts page for assistance.
We are very happy to announce that Ag-Air LLC has been selected to conduct the
spraying for gypsy moth for our 2008 program. Ag-Air LLC utilizes helicopter
application and is willing to spray blocks down to 10 acres in size. (If your
property is less than 10 acres in size you can join together with a neighbor
or neighbors to create the 10 acre minimum.) Ag-Air's has adopted a sliding
scale for application so there is a price reduction depending on the size of
spray blocks. The estimated cost of spraying will be between $42/ acre and
$27/acre depending on the size of the spray block. By combining together
with your neighbor you may be able to reduce your cost in spraying and
increase the effectiveness of the control.
After much thought and discussion within our committee, we have chosen the
insecticide Confirm for this program. We believe that Confirm is the best
available insecticide that provides significant control for the gypsy moth.
If you have contacted my office in the past, you should be receiving a copy
of your spray map in the mail soon. I ask that you review this map and call
me at 301-473-8417 if you have any questions or need to correct the map.
If the map looks fine then you should sign the map and send it back to my
office. By signing the map you signify that you reviewed it and approve
its accuracy. Your GIS map will form the basis for the spray program. If
you do not receive a map this week or have not called my office please
call me at 301-473-8417!
Our committee has also retained the services of Parkton Woodland Services
to act as the "Agent" between Ag-Air and you the landowner. Parkton will
coordinate the submission of applications with you and the contractor, and
ensure that the program proceeds in an efficient and desirable manner.
Parkton should be contracting you soon and will provide cost and contractual details.

Gypsy moth is an introduced insect pest that can defoliate trees if it is
present in large enough numbers. This defoliation normally occurs in late May
or early June when trees are most vulnerable because they have used up most of
their energy reserves leafing out. This can severely impact the health of the
tree sometimes causing it to die the same year or in future years especially
if it is defoliated again or we experience drought.
Gypsy moth needs to eat oak trees in the early stages of their development but they can
feed on other varieties when they become larger so most trees can suffer defoliation if
conditions are right. An upsurge in the gypsy moth population occurred in 2007 and it
is expected to be worse in 2008. The mountainous regions had the worst defoliation with
nearly 5,000 acres being impacted in Frederick County. Hardest hit was the east slope of
South Mountain from Rt. 40 to Rt. 77, and the east slope of Catoctin Mountain from
Mountaindale up to the Pennsylvania border. Projections for 2008 are that gypsy moth
will be active in most of our mountainous regions defoliating an estimated
40,000 acres of forest.
Unfortunately this upsurge in gypsy moth comes at a time when county, state
and federal budgets are being reduced and it is unlikely that significant
private forestland will be sprayed by the Maryland Department of Agriculture's
spray program. For this reason we have developed a "Supplemental" gypsy moth
suppression program to compliment the efforts of the Maryland Department of
Agriculture program. The intent of our program is to make gypsy moth suppression
available to landowners who are threatened by the insect if they have high
populations in or around their property. To meet these objectives, we have
approached aerial spray applicators and have asked for bids for controlling
gypsy moth using either Dimilin or Confirm insecticides. Both of these
insecticides are insect growth regulators that offer nearly 100% control of
the insect. We hope that banding together numerous properties will lower the
cost of suppression and increase the effectiveness of control. So far we
have assembled a list of nearly 300 landowners representing 8,000 acres
throughout the mountainous regions of the county.
At present there are no cost incentive programs available for the supplemental
program so landowners who wish to participate will have to pay 100% of the costs
estimated to be $30 - $60 per acre. We are still trying to acquire some
additional funding which could lower the cost to participants. If you have
already displayed interest in this program we have included your name on a
spreadsheet and will send you an application once the successful applicator
is chosen. For more information on this program please call the
Maryland Forest Service at 301-473-8417.
A.) Not every forest in Frederick County will be threatened by gypsy
moth during the spring of 2008. If you are living in the mountainous
areas of Frederick County you are at higher risk than others. To find
out more about your relative risk you can contact the Maryland Department
of Agriculture at 301-662-2074. This office has conducted surveys around
the county and has a pretty good understanding of where the highest
populations exist.
If your property is in an "Red Zone" area your forest is at risk for
defoliation. You may be eligible for the regular MDA program.
If you are not eligible for the MDA program or you want a back up program
you can call the Maryland Forest Service at 301-473-8417 and sign up for
the Supplemental Spray program.
1.You must first apply for the program by calling 301-473-8417.
You will be asked to provide your name, address, telephone and
telephone number. It would be helpful if you could provide the Map
and Parcel number of the property you wish to have sprayed.
2. Once we have your information we will include your name on a
spreadsheet for the various spray blocks we have created and map
your property using our GIS mapping program.
3. After the contractor has been selected you will receive an
application in the mail with a map of your property. You will
be asked to sign the applications, review the map and sign it
signifying that it is an accurate representation of your property,
and enclose a deposit. If you have questions or concerns with
the map you will need to contact us to revise the map. If you
do not return the application by the specified date then you
will not be part of the program. We will be using a third party
to act as an agent between you and the spray contractor. This is
being done to reduce the administrative burden on the contractor.
This agent will require a nonrefundable administrative
fee for their services.
4. Once your order is processed you will receive a receipt
and your property will be scheduled for spraying. Depending
on the contractor you may have to pay the balance of your
bill before or after spraying occurs.
5. Spraying will be conducted in late April or early May
once the tree leaves have emerged.
- You will reduce your costs and provide more effective control by
creating a large a spray block as possible. As such, you might want
to contact neighbors to see if they wish to participate.
- We only wish to spray areas that are in danger of defoliation. Please
determine if you are in need of spraying before you apply.
- There are no cost incentive programs available at present so you
will have to pay 100% of the cost of spraying.

- If you have contacted our office you are already on the list of participants.
