I hate stink bugs. They are literally coming out of the wood work of our 150 yr old farm house every time the temp hits 55* or higher. Usually they are at their most active around here in the fall, but they are everywhere right now. I have found nothing to stop them other than to seal/caulk siding, windows, door trim, etc. A lot of our windows are wood, ancient and are of the single hung-type. I'm pretty sure a small dog could squeeze through some of the jambs. Anyway, I've read that a spray bottle with an essential oil mixture of 10 drops each of clove, lemongrass and spearmint oil in 16 oz of water will repel stink bugs. Never tried it. I did use a homemade trap suggested by Virginia Tech - roaster pan filled with water and dish soap placed under a desk lamp. It caught a lot of stink bugs, but they were also all over the lamp, the dresser, the side of the pan. It seemed to attract more bugs inside than without it. Several folks around here swear by placing osage oranges (Maclura pomifera) in old mesh stockings and placing them below windows, inside and outside, to repel stink bugs. I think the stocking is for easy disposal because the osage oranges ultimately rot.
