Jena, Sorry about the time lag in this response, I am a little behind in reading the FML. I hope you get this information before they spray. I wouldn't be too worried about them spraying your area. I would suggest that you do not take your fuzzies out of the house though for 12 - 24 hours after they spray and to take your shoes off when you come in the house so they don't lick and residue off of them. Bacillus thruingiensis (Bt) is a bacteria that will inhibit the larvae from eating the foliage in the trees. Because it is a bacteria, not a chemical, it is one of the milder (but effective) insecticides, and most of it will stay on the leaves in the trees. I don't know specifically what brand of Bt they are planning on spraying, but most Bt's have a 12 hr restricted entry interval when used in a field (according to the MSDS's). this is why I said to keep them in for 12 hours after they spray. Your fuzzies are much closer to the ground than you are and weigh a lot less, so they could be affected where you would not. These are just some extra precautions that you could take. If they specifically said that it is OK for pets, then it probably is. There are some pretty strict regulations of pesticide applications. BTW, I know about this because I work in a lab that does Integrated Pest Management (IPM) studies on vegetable crops and we test some experimental pesticides (therefore I am a certified pesticide applicator). We have worked with several vegetable forms of Bt pesticided. The fact that they are using a IPM strategy is a good thing. This means that they will use other means besides just a routine spray cycle of chemicals to get the problem under control, and living in Michigan, I can attest to what Gypsy Moths can do. They are VERY nasty. If you have any other questions about this please feel free to e-mail me at [log in to unmask] Ellen and the dog house duo (they uprooted a norfolk pine last night that they had not been able to get to before) I wish they would give us the teleport secrets so that we could use it too.
