Specifically the Brown Marmorated Stinkbug which has apparently been in the US less than 15 yrs. This is my 1st experience with any kind of stinkbug.
Suspend SC (Deltamethrin 4.75%) kills them but they die slowly and you have to squirt them directly. Walking across a dry film layer of the poison seems to have no effect.
But here's the rub: Everybody goes ballistic about their odor when squished. Well, over the past seven days, I have squished about about two dozen inside the house and at least 1,000 outside on the cedar siding or in the garage with a fly swatter. I cannot smell a thing even though possessing an excellent olfactory sense. Hell, I can smell a fart at 20 yards. Guess I should be thankful small blessings in dealing with this nuisance.
