Generally, if something sounds too good to be true, it is. I don't blame people for wanting to try this, as it sounds more reasonable than most scams out there, but I would always come here or do some online research first before using something, especially something that taps into your wiring.
Now that I have read that RiddexPlus doesn't actually work, I'll stick to powdered boric acid. This is the chemical ingredient that pest control companies use, and works great! You can buy a large tub at many pet stores.
Will kill fleas, roaches, silverfish, and anything else that has a carapace, and is relatively harmless to people and pets.
