Does anyone here have to deal with Gypsy Moths? I know that the northeast has been hammered by them for years, but this year is especially bad…
I’ve dealt with them since I was a kid. I live in Western New York, and am about 20 miles from the shores of Lake Erie. We have had significant issues with Gypsy Moths since the early 1990’s but for some reason, this year they are horrible.
I planted 10 new apples trees, 10 new persimmons and 50 Swamp White Oaks this year. Adding those to the existing orchard, and I have about 150 trees and 50 apple root stocks in a nursery bed. Every tree started exhibiting signs of gypsy moth damage within the week.
The best way I have found to kill these little suckers is with Sevin. It knocks them out quickly, however I am concerned that at some point they may start building a resistance to it. Add in having to wait until blooms are over and you have a delay in control.
I finally got all the trees sprayed, and it rained. Hopefully the spray killed enough of them to greatly reduce their numbers, however they did defoliate about half of my new oaks.
IF you have Gypsy Moths in your area, what, if anything, do you use for controls?
Clarifying, right now we are dealing with the caterpillars, they are between 1/4" and 1/2" long, right between 1st and 2nd stage, where Sevin is most effective.
