mercer county, il | We spray the houses exterior down from soffits to the ground with deltamethrin, spring and fall religiously. After a year or two, they just aren’t an issue.
Old loose farmhouses, they get in the walls and behind the siding and anyplace they can, and then just trickle out throughout the year. Don’t get discouraged, keep spraying, and eventually they become a non issue. | |
