I've been battling the Japanese Lady Beatles at my house every winter since we've moved in, and it's taught me so much about both of these things- and that most seo results about insect traps etc are entirely wrong about.

I haven't figured out the sweetspot for attractant trap placement yet. It's not inside or attached to your camp or house.

But I know that cold, dry, nonstressed deaths for those that do intrude minimizes the ultimate number that invade via that route. Don't heat them, including by cleaning then up with a standard vacuum.

Interesting facts (according to me): their smell that attracts others is one of those like asparagus, that only some people seem to sense.

But to me smells like burning peanut butter toast crossed with a kaolin/ clay.

Also they hate vibrations/ noise and will aggressively attack and bite in retaliation.
