Best roach killer Powerful Sprays Baits Effective Treatments 2021

Cockroaches evolved with the dinosaurs, and in their natural habitat, they are actually a very necessary insect in the food chain. It is when they invade a house, home, or apartment that they become a nuisance.

Without any natural predators, cockroaches will quickly overrun any dwelling, and they will particularly flourish in areas that are unkempt with foodstuffs left laying about, grease from cooking that is not cleaned, and crumbs that are left on counters or that have not been swept up from the floor.

That type of environment is a cockroach’s paradise. And before you can kill them, you have to clean up their food source, or they will continue to re-infest the area. Cockroaches are notorious for their hardiness, so the best cockroach killer in 2021 on this list must be 100 percent effective from the get-go.


IDENTIFY PROBLEM AREAS WITH FLASHLIGHT AND GLUE STRIPS: When considering what cockroach control method to use, it is best to first examine your home for possible roach infestation sites. Do this by using a flashlight to search popular roach hiding spots, including behind the refrigerator, under the sink, crevices in cabinets and shelves, closet door corners, bathroom cabinets, and closets.

Use roach glue strips to locate large infestations. Based on your flashlight inspection, decide on the most strategic areas to place strips. Monitor those areas for a few days to a week. Strips in high-traffic areas will catch the most roaches, and these areas will need the most treatment.

USE CAULK TO CLOSE GAPS TO PREVENT FURTHER INFESTATION: Traps can be effective in reducing existing roach populations, but they won’t get rid of roaches on the outside trying to break in. To prevent a roach infestation from expanding, use caulk to fill possible entry points, including gaps between walls or tile, small crevices, and entry holes. It will also help to use weather stripping on doors and window seals.

PLACE GEL BAIT STATIONS TO EFFECTIVELY REDUCE ROACH POPULATION: Gel bait can be an effective roach killer. Gel bait usually comes in the form of a tube and can be applied under baseboards, in cracks and crevices, and near areas that are most likely to attract roaches. While gel bait can be effective in getting rid of roaches, it can also result in a number of dead roaches lying around your home.

Another popular method when deciding how to kill cockroaches is the use of bait stations. Bait stations work by attracting roaches into stations to feed on poison. The poisoned roach then travels back to its home location, dies, and is eaten by the other roaches, further passing on the poison. Bait stations work partially to get rid of roaches, but do not target all roaches in a home. They also pose an issue because they contain poison and look unappealing when scattered around your home. Some roach hotels only contain glue to trap the roaches, not bait and poison them. 


Boric acid, a substance found in products like clothing detergent and toothpaste, can be one of the best roach killers. Unfortunately, it is also easily misapplied and subject to displacement by air currents, sending the material into areas where children and pets can come into contact with it. Made by chemically combining boron and water, boric acid is low in toxicity to people and pets but deadly to cockroaches. When used incorrectly, boric acid will lose effectiveness and is not typically recommended as the sole method for getting rid of cockroaches. 

Does diatomaceous earth kill roaches?

DE (or kieselguhr) is a well-known natural roach killer. Products based on it are completely safe for humans and animals since they have a physical, not chemical, effect on insects. DE crystals absorb liquid from roach shells, dehydrating them, which leads to rapid death. Also, because of this feature, pests cannot develop immunity to it.
