Duh. I had heard about mothballs for spiders, but totally forgot about that when I parked the camper last fall. I'm a noob, still learning. Never heard they were also effective against stink bugs though.
Frankly, I'd consider a pricey flea collar worth the investment if it does any better than mothballs. Heck, I may go with both this fall. Critters are a PITA.
Makes sense you'd see more of them in the house over winter. As soon as the weather cools, they begin looking for sheltered places to hunker down in for the season. Normally they're pretty inactive during the cold months, but with the warmth in your home, they tend to keep on buzzin'.
Can you tell I've studied up on them?
