Just made this meme to express my frustration at Boxelder bugs. No matter how many times I carry them out they find a way back in my house in Spring and Fall.
Note because I guess some folks need it: I don't kill them, I pick them up and put them back outside!
Soapy water kills them quickly if you need to exterminate them. Just don't squish them.
There are so many it's impossible to kill them all that way. My house becomes absolutely caked in them in the spring and fall, and some of them even come into the house.
You can get an attachment for your garden hose that would let you spray soapy water over a large area very quickly.
Huh, nice.
They're related to stinkbugs right? Smell bad when squished? I've never intentionally squished one.
My old house got tons of box elders and asian beetles. The side with the most sun would be absolutely caked on sunny fall and spring days. When they got inside, I'd use the vacuum with long extension hoses to suck them up. They have a smell but I would call it stinky -- just kind of old and musty.
Supposedly the release pheromones when squished, which then attracts more of them. Not sure if they are related to stinkbugs!
