The last few years were bad here. Since I don't have an attic- log home with all cathedral ceilings- once they find a way in up top, they end up in the house and live with me all winter. I probably flushed 100 of them down the toilet from Jan to March, and vacuumed up a bunch more. Annoying bastards.
I am ready this year. Last weekend I sprayed an insecticide with a long lasting residual under the eaves, along the fascia, soffit vents, and the entire chimney from bottom to top. They are normally congregating on the south side of the house by now. I don't think they are going to be suddenly absent this year, but hopefully not as many.
