Pest repeller ultrasonic-Teddington (TW11 Teddington)

Hi, I have about 5-6 to give away. Bought on Amazon for mice, but amazon says it can also be used for insects. It didn't come with instructions. 2 different brands. I would prefer if you live in the area and don't need to travel from far away to collect, as it defeats the purpose.
