Are they just isolated to certain areas? as the response seems sparse.

Couple of falls ago I had on obscene number of the buggers on the siding of my Nashua condo. I read that they collect like that to find a winter roost. In the spring many will find their way indoors. I hit them hard with raid for a few days and had them falling out of the siding in large numbers. They are tough but it really knocked them back. See them now in greatly reduced numbers a few years later.
