The Washington Examiner says that these bugs came originally from China and have spread to 38 US states. "The stink bug is back and in much bigger numbers than last year, giving fear to a potentially historic [number] next year that has federal officials scrambling . . . "
If you are finding these creepy crawlies around your house and they are not part of your Halloween decor, you can try various ways to get rid of stink bugs. Many methods are demonstrated on YouTube.
Here is one of those videos called The Best Stink Bug Trap Ever, a tutorial for a cheap and easy way to get rid of stink bugs. It will cost about $7 to make with an empty 2-liter plastic bottle, masking tape, and some led lights. You can use this trap inside or outside.
Any stinkbugs you trap should not be vacuumed up because they will stink up your vacuum cleaner. If you step on them they will give off a bad smell too. After all, that's how they got their name. I just flush them down the toilet. I guess that's a somewhat environmentally friendly method.
