I've posted twice recently about Stink Bugs and was going to post another follow up this morning, so thanks for starting this thread.
So far, my strategy is working. Last Fall we set off 3 bug bombs in the 5er (41 feet long), and it immediately took down the hoard. We were sweeping dead stink bugs out of the camper for the next 2 weeks. After 2 weeks we set off 3 more, because we started noticing live ones again. We did this a total of 3 times, ever 2 weeks apart and finally, no more stink bugs.
Fast forward. All Summer this year, we've not seen a single Stink Bug again, until just about 3 or 4 weeks ago. So we repeated the pattern. We set off 3 bug bombs again when the camper was closed up and we were heading out for a week-end. When we reached our campsite, the spray and dissipated and there was no more smell, and dead stink bugs on the floor and everywhere again. Sweep, sweep, sweep for the next few days.
We waited 2 weeks and did the same thing again when leaving home for the next camp-out. Less bugs, but ever since we find several dead ones every morning now. The only "live ones" we find are on the outside of the camper.
I think the bug bombs sprayed it's poison into all the cracks and crevasses and anywhere bugs found a place t enter. When the bugs do crawl through, they are now rubbing against the dried bug bomb spray and it kills them before they have a chance to populate inside the camper, or worse, reproduce.
The only thing we do after igniting the bombs is to wipe down the counter tops, the stove top, the kitchen table, and wash the bed linens. These are items we do all the time anyway. In addition, the floor gets swept clean and mopped at the end of every week-end, if not sooner. We have no carpet, but do have throw rugs, and they get washed occasionally too.
We make sure all the dog bowls and all food is stowed away before setting the bombs off. They's why we do it right before we travel, everything is stowed away.
Bug bombs do work against Stink Bugs because they will penetrate every crack those bad boys can enter and the residue left behind will continue to work for almost another 6 or 7 months.
If you do this, you will find them dead on the floor, in your window tracks, on top of the refrigerator, on counter tops, in shoes, under floor mats and rugs, under furniture, pretty much everywhere. BUT!!! they are dead!
FYI, we get the cheap-o 4 pack of bug bombs from Dollar General. They work pretty good. And oh ... we have no spiders or ants either.
