You can buy spray bombs that will cleanse a house of asian beetles for a long-long time...in fact, I don't know when they'll be back. These "bombs" are the type you sit in the middle of the room & activate them. Obviously, no human or pets should be around while this is going on. Read the label carefully. It's better if you can be gone for a day. But, the biggest secret I found was to put the bug bomb in the crawl space. That is where they were living. After I did that, all crawling forms of life ceased. That was fine w/me.

But again, read the label carefully & follow directions. These things are sold at places like Menards & Lowes home type stores. No license required.
