How to get rid of
Stink bugs or shield bugs are as long as they are wide. They are shaped like a shield and come in many shades of browns, greens, and red.
They become clear when in the spring and fall, often following your lights, bazillions of them land on your house or building as they look for a place to winter over. Thousands of them, then crawl inside through any convenient opening. The bug lives up to its name real fast when you have vacuumed up a bunch of them and forgot to take the vacuum bag out to dispose of them and they have now begun to smell awful.
HOW TO PREVENT STINK BUGS:
The only advice is to seal them out by closing every crack or crevice or hole where they can enter your home.
HOW TO KILL STINK BUGS:
Insecticides sprayed down into cracks will kill the bugs but it is not recommended because the decaying bodies will stink.
It is better to vacuum them up and discard them in the trash or feed them to your fish or guinea fowl.
