“Got 2 of these Zap Traps as lots of mosquitoes outside sitting with friends at the dog park in the early evenings. I was expecting them to be “rechargeable” due to the USB reference. After leaving it plugged in overnight, I realized the USB needs to be plugged into a live source (laptop or charging station) to activate the Zap Trap. Good that it has the battery option which makes it truly portable. Now hope it works!!”
