Types of Roach Killer:

You can get these products in multiple variations. For example, traps, gels, sprays, foggers are handy to eradicate these creatures.

Roach Killer Traps:

It is a ubiquitous roach killer product that comes with “roach motels.” To lure and kill this creature, a few trap models come with baits that remain in an enclosed space and contain poison like Hydramethylnon. However, a few models come with one-way doors that help to keep the cockroaches trapped. As these models don’t use poison, they are safe for your children and pets. But compared to the poisoned traps, these designs are less effective.

Roach Killer Gels:

Cockroaches get attracted to these substances very quickly. These gels contain a potent insecticide that we know as fipronil. Due to the scents and tests of these gels, these creatures get attracted to the poison. After that, they eat the gels. As soon as they eat, they will die. Then, other cockroaches consume the dead one.

As the other ones eat the poisoned roach, the bane gets spread through the nest. You can apply the gels easily on the ground, walls, behind appliances, or cupboards. But if you have children and pets in your house, then make sure that you are not placing these gels in easily accessible areas.

Roach Killer Sprays:

If you want to cover a wide surface area, then you should use sprays. By applying sprays, you can cover those places where previously discussed two methods couldn’t reach. These sprays contain pyrethroid chemicals. The primary function of the chemicals is to destroy the nervous system of these pests.  As soon as the insects encounter these substances, they will die (within a day). However,  a few roaches can remain alive up to fourteen days after this treatment.

Roach Killer Fogger:

This roach killing type is acquainted as “bug-bomb.” You just need to place these cans of pesticide in your room and allow these cans to remain open so that the pesticides get activated. As soon as you will do this, it will release gaseous poison. Then, the poison will seep into crevices at your house.

These pesticides usually use Pyrethroids to harm the nervous system of these creatures. It works similarly to the sprays do. But make sure that you are not using Fogger without covering foods, cooking implements, and cooking surfaces. After using the pesticide, you need to vacate the room for at least four hours.

  • Identify Problem Areas With Flashlight And Glue Strips:

To eliminate roaches, first, you need to detect the areas in your home where roach infestation occurs. To do this, use a flashlight and find all the sports where the roaches may hide. These pests usually hide behind the refrigerator, under the sink, crevices in cabinets & shelves, closet door corners, bathroom cabinets, and closets.

  • Use Caulk to Close Gaps to Prevent Further Infestation:

If you want to reduce the existing roach populations, then traps can be an effective way. But if you’re going to prevent the aggrandizement of roaches, then you can use caulk to fill the gaps between tiles, walls, and other areas through which these creatures can enter. It doesn’t allow a roach infestation to expand.

  • Place Gel Bait, Bait Stations To Effectively Decrease Population

Gel Bait is an effective roach killer. You can get this bait in tube form.

You can use the bait stations also which is one of the standard processes to kill these pests. These lure the pests to come into stations and to eat the poison.

But following this way, you can’t get rid of all the existing roaches in your home. A few roach hotels come with only glue to trap these insects.

  • Boric Acid Powder For Added Effectiveness

Boric acid is one of the primary substances that you can find in clothing detergent and toothpaste. This one is one of the best roach killers.

How Does Cockroach Gel Work?

The roach gel mainly attracts pests and lures them to poison. Compared to the roach killer spray, the gel bait is a more strategic weapon. These gels can kill the entire colony of the roaches by allowing the poison to spread among all the cockroaches who will eat the poisoned one. Thus, it helps to decrease the population of these pests.

How Effective is Roach Gel?

Whether it comes to kill a large or small roach, the belt can work effectively. You can use these gels even against the smallest roach invader, i.e., German cockroach, and get effective results.

According to a study, only one insecticide gel application has eliminated about 99% of German roaches within 30 days. Moreover, after one week of applying this Gel, around 3/4 of the roaches died.

The gel baits help eliminate the roaches from hotels, schools, hospitals, warehouses, restaurants, food handling facilities, supermarkets, commercial and industrial buildings.

How to Use Cockroach Gel Bait?

Here, we have given simple steps that you can follow to use the gel bait.

  1. Choose the Gel Bait.

A good gel bait will not work like a bug killer spray that can kill the roaches only when they come into contact with it. Instead, these gel baits react slowly and permit the poisoned roach to spread the insecticide among the other roaches. These baits consist of active ingredients such as Hydramethylnon, Fipronil, and Imidacloprid. As per the research, Imidacloprid works effectively against German cockroaches.

These baits are available in two forms— liquid Gel and bait stations. The bait stations are mainly small plastic cartridges that help to hold the gels inside. Each of these forms of bait is very effective. At the same time, you can apply the gel bait even in tight corners.

But how do you come to know whether the bait will work or not? If you want to test these baits, you can feed them to the roaches with your hands. It will help you to gain control. Moreover, you can follow another test to get your answer. It would be better to keep an eye on the amount of bait left after every night.

It will finish more baits, the better result you will get. But if you find the bugs not eating the bait, you need to go for another product. Or, you can detect the place from where they are coming. Otherwise, you can place the baits in different spaces.

The most common bait brand is Advion. It is the most demanding gel bait product in the market. This model uses a non-repellent formula that attracts the cockroaches easily without giving any hint of chemicals.

On the other hand, indoxacarb is a very active ingredient. When a roach eats the poisoned bait and dies, other roaches ingest the poison by consuming the dead roach. Thus, it helps to control pests.

  1. Apply Gel in Cracks and on Surfaces and Crevices.

If you want to get the best results, apply the Gel near the areas where the roaches mainly hide (For example, the crevices). Remember, every day; only a few roaches indulge in searching for food. Therefore, if you put the bait closer to them, you will get better results.

While using the Gel, put a small pea-sized drop of it. As a result, the cockroaches won’t feel confused or threatened by the bait and eat the entire bait.

Sometimes, you may face large infestations. Then you need to apply the drops in different locations, maintaining 3 inches distance between each spot. If the colony is small, you need to put the drops 2 to 3 feet apart. If you spread 5 to 10 drops of Gel throughout your home, it will be enough for killing both small and moderate roach infestations. Check the kitchen and bathroom properly, as roaches mainly hide in these areas.

  1. Monitor and ReApply

As soon as you apply the bait, you will start your waiting game. It may be difficult for you to know whether the bait is working or not during the situation. If you see the roaches lying dead near the bait, ensure that the insecticide kills them very quickly.

You need to apply the Gel again if you see good results after applying one time. On the flip side, you can leave the bait station in a place for a few months until the bait inside it gets consumed.

How Long Does a Roach Killer Gel Take to Work?

After applying this Gel, you will get to see dead cockroaches within just a few hours. However, you may see effective results within a week. At the end of the month, more than 90% of roaches will die. However, it would be best to continue applying tiny gel drops until the roach activities get stopped.

How to Make Natural Cockroach Killer:

Here we are going to elaborate on one of the most effective cockroach killer home remedies. Let’s figure it out.

First, you need to make a mixture of a batch of borax and sugar. Then you need to combine these two properly. Then, your task is to apply this mixture in cracks, under cabinets, sinks. Apply it in all those places where you see the roaches. Apply this mixture again until you get rid of the roaches. However, you can put the mixture in a small container rather than dusting it on the home’s surfaces.

Why This Works

The roaches prefer the sugar, and that’s why they consume that mixture. As soon as they finish these, the borax will damage both the digestive and outer skeletons and lead the insects to death. It acts similarly to boric acid.

Best Roach Killer Buying guide

Length of Efficacy:

This factor indicates how long the roach killer can work. Usually, the length of efficacy of a roach killer relies on two things— how fast the active ingredient will break down and the amount of product you are applying. Most of these products have at least one-month of efficacy. At the same time, the maximum effectiveness of the products is two years.

Sometimes, the large infestations need extra traps. It is because the poison can be consumed too fast, as a massive amount of cockroaches are engulfing it. Before applying the product, you need to check the instructions given on the package. Along with this, make sure that you have checked the time when the product needs to be replaced.

Types of Pests That the Product Can Eliminate:

The pest types that the product can remove rely on the product’s active ingredient, the type of product, and the bait used for luring the pest.

A few larger traps come with a glue sheet.

Therefore, most of the roach killers contain ultimate levels of pesticide.

These can kill various other pests like bees, ants, hornets, mice, spiders, rats, and silverfish. That’s why it is essential to keep your kids and pets away from these products and the spots you apply them.

Type of Bait:

There are mainly main types of bait and come with fipronil, hydramethylnon, indoxacarb, or boric acid. The first bait type includes sugar and poison. The sugar helps to attract cockroaches. At the same time, the poison helps to kill the insects fast. Mainly roach motels and other traps (traps that can kill the cockroaches on the spot) use this method.

The second bait type uses the same mixture of sugars that intends to attract the roaches. In this case, a delayed transfer toxic action is used. It takes several days to kill the roaches. During this period, the affected cockroaches leave poison-laden feces in their nest. As soon as it dies, other roaches die quickly by consuming the dead one. This one is a very effective way that can help you to get rid of cockroaches.

Safety Factors for Pets and Children:

Before you treat any roach infestation, first, you need to ensure the safety of your family, pets, and yours. The traps and gels come with bright colors, sweet smells, and sweet taste.
