Our Second Choice

Harris Boric Acid Roach Powder With Lure, 16 oz

A cheap, and very effective roach killer. This bottle can literally last you a year, and in most cases will get rid of your cockroaches almost instantly! Harris Roach Killer Powder uses boric acid with a "special lure" - Roaches will carry the powder back into their nest, and gather points which will kill the entire infestation. It comes with a tube-like straw that will allow you to get the powder into hard to reach places. This is not a marketing scheme claiming anything special, it just uses a proven roach killer powder formula that actually works (99% poison 1% bait); making Harris Boric Acid Powder one of the best roach killers on the market.

Our Gel Pick

Combat Source Kill Max Roach Killing Gel, 60 Grams

Combat Kill Max uses a formula that contains water and food that will end up killing the roaches. The gel can be used anywhere and is very easy to apply areas that you have seen cockroaches. The formula does work, and will eventually kill all your roaches - but it does need to be re-applied occasionally and the killing process is not as fast as the top two best cockroach killers.
