Nobody likes having cockroaches in their house. There's no need to hire an expensive pest control company to take care of your problem, there are products on the market that can effectively kill roaches, without putting a hurt on your wallet. Our experts took a look at the formula, price, and effectiveness to find the absolute best cockroach killer on the market.
Best Roach Killer
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 uses Boric acid powder with a secret "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 popular formula that actually works (99% poison 1% bait).
This product is very similar to Harris Roach Killer. It also uses Boric acid, which will eventually kill all the roaches in your house, because the roaches will literally poison all the other roaches. Pic Orthoboric Acid does not seem to have the "secret" bait, and doesn't come with a tube so it's harder to insert into tight areas. Still a very effective and proven formula.
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.
