My family has a cabin in a wooded area of Otter Tail County, MN. We have a serious problem inside the cabin with an infestation of Japanese Beatles. The problem is persistent and increasing. Each time we arrive there we have to vacuum hundreds, if not thousands, of dead and living beatles, upstairs and downstairs. We empty the vacuum canister outside, and leave the canister outside overnight to be sure that any (most) living beatles get out. But there are immediately more that begin to emerge indoors. We have recently installed new windows and re-sided and re-roofed the entire cabin over the winter. It seems that the majority of the beatles emerge in the bathrooms (one upstairs and one downstairs), but they also accumulate in the kitchen area around large picture windows. In the past, we saw the beatles in the fall, but now they've turned into a year-round problem. Can you please provide any suggestions of how to eliminate them (short of burning the place down!)? We are desperate! Thank you for any help you can provide.
