When I got over-run one time I used the long hose of a vacuum cleaner to suck them up from all their hiding places... Then I would go dump the vacuum and do some more... My trailer has the air conditioner duct built into the ceiling foam from one end of the trailer to the other. This was plum full of them...
We had them real bad here in Northern Neck VA a few years ago. Last year I thought they were going to be bad but wasn't... The year they so bad here a few years ago the local TV guru's keep telling everyone how good they were to cook up and eat them... I guess alot of that went on for awhile around here haha... Not me however....
