Riddex — Fraud and scam
Not only does the product not work, the shipping charges are HIGH ($17.90 for the two small boxes). Tried using Riddex in garages after Hurricane Ike. Anything that ran in for shelter was not bothered by this product. I think the roaches prefer it to the good old fashioned roach spray. Maybe it's an aphrodisiac for them.
I am currently, I'm in the process of returning the product. It appears I will need lots of luck from what I've read on this site. Do not believe the hype you hear and read in their advertisements. It is pure B.S.
