Just found one in my house. Following.

They are pests here. I don’t know what they do outside, but I’ve heard they can be damaging. I hate having them inside.

They are everywhere here. My tomato plants were an unfortunate host for them this year but they dd not seem to really cause any damage. They seem to be more of a nuisance. Ladybugs are much worse for me right now.

Oh. I hate these things. Yuck.
They came in from the East Coast route to here in Ohio. One year- nothing.
The next, and from then on- wow.
The Ohio State University was doing research on the problem, species, etc., but I couldn’t find any recent enough info for you to help. I’m sorry. One article did say that the US is at the point where annihilation altogether is no longer an option.
They no longer have to go out to collect samples, just go outside!
The beetles are under the siding, and inside the tracks for the windows, where they can’t be reached!
Come the slightest breath of Fall coolness and there they are!
They sit, lifeless until it warms up- they fly at your head when inside during Winter. Not the light bulb nor lampshade- noooo, your head. ( it seems that way to me!)
Do Not squish them- euw.
Do Not let any pets ‘play’ with them to end up eating or biting them.
They are slow, and have legs a little less icky than June Bugs.
I pick them up in a tissue and pitch them out the door. Do they fly back- I don’t know. They usually can’t get back to warm that fast.
Caution! If you open the window to put them out- others will drop down out of their hibernation areas, along with the dead. So unless you have a hazmat suit- I wouldn’t. Friend sucked them up in vacuum cleaner- only to have them ‘take’ to the nooks and crannies. She dumped the filter and contents collection inside the cleaner- but the ones that snuck by-were roosting inside the cleaner.
I do worry about a new predator being introduced to kill the beetles. That action always has always brought in more trouble than the original problem to begin with, in the past.
Too bad they don’t eat the Invader Kudzu Vines that kill everything, from the same point of origination. :/
Good luck!

- one suggestion- might be best to look up some of the research being done at your nearby universities, etc. for the latest -where you live. How it effects your particular area. Just a thought.

This seemed like good advice. But this was for spring not autumn. Either way, good tips.

Thanks very much, everyone. The DIY solution seems very practical and sensible—a good place to start. As with so many other things, though, if I do this and my neighbor doesn’t, we’re not going to beat the problem.

At least the damned things don’t bite or munch on things in your cupboard.
