Kills roaches instantly? Best Roach Killer for Apartments

Roach killer target environments to achieve maximum results. Gel baits are 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. 

While pesticides are recommended to kill roaches, diatomaceous earth, and Boric acid can help kill the roaches instantly. Diatomaceous earth will break the roaches’ exoskeleton, take up its body fluid and lead to death. 

Here are the steps you must take instantly kill roaches in your home: locate roach baits in areas that bug frequent, mix peanut butter and boric acid to make a trap cake for roaches, pour diatomaceous earth in areas where roaches will be moving, remove all water sources or clogs in the apartment. 

Types of Cockroach Killers

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

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. Powder 

Some of us sometimes just need a product that’ll work with no complications such as becoming toxic to kids and pets. If you’re anything like me, you’d thus go for some of the powdered roach killers such as Boric acid/ borax powder

Boric acid is naturally found in the ground and they act through contact and ingestion. Borax will stick to the bug’s body or they’ll eat it and damage its nervous system causing fatality. 

However, the interesting bit is that the roaches will carry the boric acid back to their nest and poison the other insects and hence may help wipe the whole roach population. 

6. Roach Killer Bomb

Roach bombs or foggers are effective in treating a large cockroach infestation. However, you’ll need to learn when to use the best roach bomb for the house 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.

How To Choose the Best Roach Killer for Apartments

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 a large apartment or for a smaller house. 

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. 

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.

The active ingredients in your Roach Killers? 

Whenever you think about choosing a roach killer for your house, you must consider how toxic its active ingredients are if, by any mistake, they land on the wrong hands.

1. Fipronil 

Some pesticides are highly toxic (and result in health complications) if eaten by pets or kids. This is because the kid’s kidneys, liver, nervous system, and brain are still underdeveloped and won’t easily handle the harsh chemicals.

For example, the Fipronil ingredient in roach killing pesticides is highly toxic – they damage the insect’s central nervous system. If human beings and pets eat it, they’ll experience seizures, dizziness, headaches, and sweating.

2. Hydramethylnon 

Practically, hydramethylnon works like a great stomach poison for roaches that hinders the energy generation in the bugs. This ingredient is common in Combat cockroach Baits. The main technique to have roach killers with this ingredient to work effectively to improve the sanitation of your apartment. 

Thus, you’d need to clean any water pools and food debris that would be lying around your house. Therefore, in addition, to increase chances of the bugs feeding on the hydramethylnon laced bait, your house will also attract less new roaches. 

3. Indoxacarb 

Indoxacarb is described as “low-toxicity” (doesn’t bring mutagenic or carcinogenic issues) and will control cockroaches and ants. This ingredient kills roaches through contact or when the bugs eat food or plants that are laced with the Indoxacarb. 

A 2008 research reported that one insecticide treatment with indoxacarb kills 3 roach generations. Its mode of action is through preventing regular movement go sodium ions through the roaches’ nerve cells.

This causes paralysis and poor nerve function and finally death. Advion Roach Bait Gel is an example of a roach killer that contains the Indoxacarb ingredient. 

4. Zeta-Cypermethrin and Bifenthrin

The Zeta-Cypermethrin and Bifenthrin ingredients that’ll eliminate crawling bugs including cockroaches. For example, Bifenthrin damages the roaches’ nervous system which results in paralysis and eventually fatality. Beijgn people and pets safe, this ingredients is appropriate for home use in addition to its features of being odor free and non-staining.

5. Bifenthrin

Bifenthrin is derived from pyrethrum and its mainly used against roaches and red fire ant. Like the hydramethylnon above, this Bifenthrin damages the bug’s nervous system. 

On the products, the Bifenthrin is contained in Ortho Home Defense Max that we’ve reviewed an earlier in this post. 

6. Cypermethrin and Imiprothrin

Cypermethrin and Imiprothrin ingredients are readily used in Raid insecticides that target roaches. I noted that these ingredients allow the spray to leave a great smell in your apartment – and thus won’t have a bad odor.

7. Imidacloprid 

Imidacloprid is an active ingredient in roach killers such as Invict Gold Gel (about 2.15%) and it has features that make it almost similar to nicotine. Imidacloprid works through ingestion and contact. 

Nicotine, found in tobacco, that hinders stimuli transmission for the bugs’ nervous system. This ingredient is mainly used to target German cockroaches. 

Imidacloprid will block the nicotinergic (the neuronal pathway) that mainly causes acetylcholine accumulation, paralysis and eventually the roach dies.

6. MetaActiveTM 

MetaActiveTM is a strong insecticide ingredient that’s great for a wide range of roaches such as Asian, Australian, and German roaches. Its mainly used in the home, commercial and industry roach control particularly where the bugs have grown resistant to the available bug baits.

Conclusion

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.
