Do you have an instruction manual for a Sunbeam pest repeller SB 310?

SOURCE: roaches are living in your ultrasonic pest repellers...they love them...will send pics if needed

dont' think those things work for any lenght of time - best thing is poisons or sprays or just good hygiene (remove all food sources)

SOURCE: Does the sunbeam pest repeller effect dogs

it is always safe to assume that any chemical that kills insects and pests will affect pets
you can go google and type in ---material safety data specifications for ( you type in the active ingredient or trade name of the pest kill*r)--- that will give you a pdf version for down load and those sheets will tell you all about the chemicals and the toxicity to animals , people and the environment
