I don’t have an effective answer for you on this particular Q, but I do have some advice. Read Augusten Burroughs’ memoirs and short stories based on his life. He’s funny as all get-out, and he has the same anti-bug mania that you seem to have. His accounts of how he deals with insect pests in several stories are simply hysterical. You may not get any tips on fighting the critters, but you’ll laugh so hard you might forget that you wanted to in the first place.
