Using a strong adhesive (syrupy bait), the trap will get hold of the roaches on contact – but has some slight odor. Therefore, it’ll be a great alternative to using pesticides or poisons in the roach killers. It’ll be functional for roughly 2-4 months.

The adhesive has some attractant for the cockroaches. However, avoid keeping the trap in areas with dirt and dust as it might cover the syrupy bait, which will significantly reduce its effectiveness.

However, you might still require to employ contact roach killers such as those with  Raid Ant & Roach Spray. I noted that this roach bait will work for kitchen areas (like cabinets or cupboards) and food areas because it has no poisons. However, keep pets and children away from this bait as they might be unable to remove themselves from the sticky setup.

The ultimate 4-Pronged method to kill roaches 

The best 4-part method for killing roaches consist of Traps, Baits, Sprays, and Growth Regulators (IGR). Roach killer is defined as a chemical or device used to kill cockroaches. Modern roaches require a warm and moist environment to survive.

Therefore, roach killer should target such environments to achieve maximum results. Gel baits are currently the most accepted roach killer since it has a mixture of attractant and poison which causes chain death of the roaches and the insects that eat the dead roaches.

1. Roach Traps 

Roach tarps of bait stations provide a no-mess method to control the roaches in your apartment. The baits attract the roaches with an enticing chemical smell, and thus they eat the bait and die.  

Further, roach traps employ both a trap and a containment technique to control the roaches.  Also, the roach trap will injure and contain the roach if it tries to escape if the poison bait does not kill it.

Bait stations are designed to kill the roach slowly. After consuming the bait, the roach carries the poison back to their nest and disperse it to other insects.

2. Roach Baits

Roach bait is an indoor roach killer that exploits the emetophobic, coprophagic and cannibalistic trends of cockroaches. There exist varied types of roach baits which are utilized for different species and area. Roach bait gels may be used both indoor and outdoor.

Further, Granular baits are mainly used in outdoor spaces such as mulched areas in which roaches hide and breed in the house. However, they can also be used in wall voids and attic. To control the roach colony, the baits should contain Hydramethylnon 2% and Fipronil 0.05%.

However, avoid using baits together with insecticides. The insecticide can contaminate the bait and thus would neutralize the domino impact and thus would not attract the insects. Also, if the roach would die before distributing the bait to the other insect population.

Equally, use the same principle while baiting insects. It is important for the foraging worker ants the bait carry the poisonous bait back to the ant nest.

3. Roach Sprays

Most of the users love roach spray apart from some that have pungent smells. The sprays have D-phenothrin and prallethrin as the active ingredients.

The pyrethrum ingredient enters the roaches’ cuticle to bind the nerves’ sodium channels and thus stopping body activities such as heartbeat and breathing in the apartment. Despite being a very harmful nerve agent to roaches, the pyrethrum is nontoxic to human beings and other mammals.

The roach sprays can be used on cracks, crevices, and furniture to reach the roach nests effectively.

4. Insect growth regulators (IGRs)

IGRs are categorized as insecticides that do not kill the roach instantly but adversely affect its ability to grow and mature naturally. They operate by either blocking the cockroaches’ ability to reproduce or grow into an adult.

Therefore, the IGR will ensure that the roaches in your house do not develop another generation in their population as it will curtail their capacity to grow or reproduce.

Further, some IGRs mimic the natural growth hormones and are thus named juvenoid IGRs. They affect the length in which the roach remains in the larval or nymphal stage and the time when it turns into an adult.

For example, when you expose the cockroach nymphs to the juvenoid IGRs, they develop infertile adults or will not molt into adults. Also, the chemicals can affect the roaches’ adult life by blocking the creation of viable roach eggs. As a birth control method, the IGR will help prevent the development of roach babies or tiny roaches.

5. Roach Bomb

Roach bombs or foggers are effective in treating a large cockroach infestation. However, you’ll need to learn when to use a roach bomb as it can be less efficient in roaches that are hidden in voids.

Place the roach bomb at the middle of the room and set it off to allow the insecticide to move up and settle down killing roaches on contact. 

Buyer’s Guide

Therefore, it is important to find an appropriate roach control method that will kill the bugs that get into contact with it and those that are holed in the racked nest.

Experts have varied opinions on the order in which cockroaches belong to, whether: Orthoptera, Dictyoptera or Blattodea. However, roaches cause both embarrassment and health consequences.

How To Choose The Best Roach Killer For Your Home

Tip: You should choose the Best Roach Killer depending on where the roaches in your house are hiding.  However, you might require more than just one kind of roach killer. For example, for a large apartment, you might use the Home Defense MAX, or for a smaller house, you can use the Gel to kill roaches.

While you might enjoy catching some roaches roaming around the house, it is no secret that there is a whole colony that is hiding at some location in your residence. However, spray insecticides will kill the roaches only on contact.

Therefore, you should target the roaches in the areas they breed and live, which makes Bait Strips, Gels, and Combat baits to be highly effective in roach elimination.

Cockroaches enjoy living in water and dark conditions that have water and food. Also, bathrooms and kitchens are excellent nesting areas for roaches. After creating a nest and accessing enough food and water, the roach population will increase rapidly.

Therefore, you will only see the roaches when they are looking for food, water or when they are migrating to a new nest when their population has grown too large, or they are escaping from insecticides.

Therefore, it is critical to target the right places using the correct products while trying to control roaches in the house. Combat is created from carbohydrate-rich attractants which highly attract roaches.

The roaches that roam in your house searching food and water will eat Combat and spread it to the rest of the population in the nests. The roaches spread the poising through feces, sputum, and carcass.

Combat Gel will help you control roaches in areas that are difficult to reach in the house. The gel’s characteristic feature will fit into crevices and cracks which the roaches use as entry and nests. Further, you may use the gel to fight roaches on pipes that act as an entry into your house.

Bait strip will be effective to place under shelves and the garbage lids since they have an adhesive area to allow easy concealment from pets and kids.

Roaches taste the food and other substances using their feet. German roaches love light Karo Syrup, brown sugar, proteins carbohydrates, and sucrose. However, when you mix sodium borate or boric acid, food-grade Diatomaceous Earth baits; ensure to keep them out of reach of children and pets.
