A couple weeks ago I installed a bug zapper. Ever since, I've been having to clean the thing out every day because it fills up with dead mosquito carcasses overnight. If I forget to clean it out even once, it's extremely difficult to clean the next day. I've already gone through two cans of compressed air.
You'd think thousands of dead bodies would give the mosquitoes some clue that this is a bad place to be, but no, the stupid bugs just keep packing themselves in.
Now if only I could find something that would do the same to the horseflies.
