These few personally selected poisons are highly effective against cockroaches and will destroy the whole colony within a matter of minutes.

I have tried and tested these roach poisons and have thoroughly reviewed them. All these roach poisons are intended for professional use. However, if you are using it at home, utmost safety measures should be taken to prevent poisoning.

List of Best Poisons for Roaches

1. Demon Max Insecticide

Demon Max Insecticide tops my list of the 3 best poisons for roaches because of its extreme effectiveness. The product has proved to be effective for various insects, including battles, cockroaches, termites, spiders, fleas, and fire ants.

The gallon comes with a top measuring part for making the pesticide solution easy. Once I sprayed the roach pesticide, hundreds of cockroaches were dead within hours. Many of the roaches even didn’t get time to escape their nest.

However, one thing that is worth mentioning is that the product is the best chemical to kill roaches but is highly poisonous and harsh. Without proper masks and gloves, it can prove disastrous. I tried to use the product without a respirator mask, but it kicked in so fast that I had a severe episode of cough and sneezing.

Moreover, it is highly recommended that you spray Demon Max indoors before moving in. Otherwise, it may destroy certain items on contact, such as wood varnish and paint.

2. CSI Viper Insecticide

You can use CSI Viper Insecticide both indoors and outdoors, but I believe that the product’s strong smell makes it unfit for indoors. However, no doubt, I found the product to be the second strongest insecticide for roaches available.

WITHIN HOURS, the CSI Viper effectively killed many insects, including roaches, ants, fleas, and spiders. It also comes with a measuring column. So if you want to make a gallon of insecticide spray, all you need to do is remove the cap off the measuring side.

Next, slowly squeeze the belly of the bottle to fill the measuring column up to the 1 oz mark and pour down it into your 1gal spray tank. The last step is to fill the spray tank with one gal of water, and your solution will be ready.

The bad thing about the CSI viper insecticide is its strong and pungent smell that remains for days to weeks after use. It can also make your pets go crazy.

3. Tempo Sc Ultra Premise Pest Control Spray

Roach-killing products such as Tempo 1% Dust from Bayer have never disappointed me. Similarly, Bayer has also provided the best poison for roaches in the form of Tempo Sc Ultra Premise Pest Control Spray, which is very effective and lethal against indoor pests and outdoor pests such as Gall Mites, Bagworm, and Aphids.

I found the product extremely effective and with excellent residual effect. One of my friends who has a pest control agency has been using the product for many years and insists that other professional exterminators use the same.

He told me that he has never documented resistance against Tempo Sc, whereas insects quickly become resistant to other products after multiple applications.

Keeping the pros aside, two things that make me feel the product is not fit for everyone,

  1. It is very costly as compared to other products
  2. Destroys oil and water-based paints within minutes
