This was sprinkled beneath my fridge to remove roaches in my apartment. After 5 days of sweeping up dead roaches, they were gone from the apartment. Every 3 months I applied it and I’ve not needed an exterminator again. It is important to only apply away from children or pets!
This is the best product for killing roaches, though, it is not advertised as such. Between all of the other most powerful roach killer alternatives, this has been the best ant and roach killer which is more helpful since it tackles two problems at once. Reuse every few months though!
I sprinkled this around the perimeter of my kitchen and used outside in a gallon sprayer with water every 60 days for 2 years now. It is the best store-bought roach killer because I finally do not have to worry about them in my home or around my family.

Buyer’s Guide

Bug infestations are never a pleasant thing to deal with. Such things as roaches, ants, fleas, beetles, stink bugs, silverfish, and more can breed, populate, and spread in houses, garages, and decks extremely fast. They especially like to hide and repopulate in dark, damp, out of the way places. Pests can especially be dangerous around food and children since they can transfer many different allergens.

There are numerous questions to ask as well:

What is the best indoor roach killer?

The best indoor roach killer is one that will tackle infestations both short and long term. This could be done with direct contact sprays, boric acid tablets or baits or powders, which requires the cockroach to ingest or walk through and then it will sink into their skin. These are the main ways to deal with it short term. Sometimes, they can bring it back to the nest and kill off the entire group, which will help lead to a more long term fix. The best roach killer product is one that will kill the ones walking around but also the baby roaches in the nest to prevent further infestations.

What is the best roach killing bait?

The best anti roach bait is the one with the built-in lure. This will ensure that you do not leave a random bug killer around that is not actually killing the roaches. Hence, it will not only lead to a greater kill rate of roaches but also protect those in the home from residual chemicals that last a while without killing anything.
