Does crushing stink bugs or Asian lady beetles attract more of the same, or is this a myth?
Every spring and every autumn we are infested with lady beetles. Not the ladybugs that everyone claims are good luck, these are different. And they are a nuisance. I have been told repeatedly to be careful not to squash them, because they release a scent that attracts more beetles.
This autumn we were extra lucky and have been taken over by stink bugs along with the lady beetles. I’ve heard the same is true about squashing them.
So, my house is full of bugs that I am afraid to kill, because I don’t want more bugs.
Why in the world would a creature be attracted to the scent of its dead buddies? What kind of evolutionary advantage can there possibly be to that?
