Thanks for hilarious comments. ‘Glad we’re not alone! They come out of our outlets, shower heads, invisible holes in the wall. Basic conclusion: EVERYTHING kills the little suckers – shoot, water or a finger works great! KEEPING them out is a whole ‘nother deal. We’ll try the Boric acid – sounds like the ratio is the big trick – and yeah, it does seem to help to clean vehemently, get rid of every crumb, vacuum, yada yada. At least they don’t bite. Too bad they can’t clean!
