Is it because we had a mild winter, as Matt suggested? I don't know but two nights ago I was knocking them out with a broom (about 10 in my hall) and knocked the thermostat off the wall and broke it. I will have to call my heating man to come fix it for sure.
Two days ago I found out where about 100 were sleeping? in the daytime -- under the pads on my chaise lounge. I battled them with the broom one day and the hose the next day. Today I did not see any. Another place I have been squirting out everyday is the top of my lattice under my deck. Hundreds would fly out of there. Not too many today.
When I say Sadie--she is the one who noticed them first and was attacking them on the deck and in the patio door. One day when I opened my front door a flurry of them flew--I opened the screen door fast and they flew to the sun, thank heaven. Today when I got in my car, some flew out. How could that be??? I found they had tucked themselves into the rim of the door--so had come from the outside.
I am worried that some may have gotten into my closet but I have not found anything safe to put in there yet. I guess I will have to make my own sachets--the moth balls are too dangerous.
Still, the question is, why are they so plentiful, what does it mean? And have I ridded myself of them, in the house at least??? I surely hope so.
