Looks like a cheap tennis racket...but its a handheld bug Zapper I picked up at a garage sale for 25¢.
Its called the Charcoal Companion, and though I got it new in the package, I wanted to know more about it, so I found it on Amazon for $12.
It does not feel good if you touch it when you press the button, but I couldn't resist.
It's best for flies, gnats, mosquitos, but it also works on bees....or I should say, it stuns them but they could fall off and wiggle for a minute. Best just keep trying...they'll die eventually.
I haven't tried it on a spider yet.
Sent from my coffee pot.
