You're pretty much out of luck, I'm afraid.
They come out whenever the weather warms up to a certain temp. The infestations are annoying, but don't last forever.
As far as 'bug attacks' go, they're pretty harmless. They don't bite or sting, and although they do smell if you squish them, I'd rather have them than bees, wasps, hornets, or horse flies.
Nothing short of fogging the whole house will help, and even if you do that it still won't take care of them getting in; it just means they'll die faster.
