When you’re dealing with a cockroach infestation, it’s important to think of the future. Cockroaches are likely to lay eggs, and they have a fast reproductive cycle. Even if you clean your home from top to bottom, there are likely hiding places that you’ve missed where larvae can thrive. So how do you keep an infestation from recurring with the next life cycle?

One of the simplest solutions is to use an IGR insecticide. In addition to killing the insects that already exist, IGR insecticides interrupt the growth cycle. They prevent eggs from hatching, kill nymphs, and prevent larvae from reaching maturity.

#1. Zoecon Gentrol Insect Growth Regulator

This sixteen-ounce spray can of insect growth regulator from Zoecon works by using a low concentration of hydroprene as an active ingredient. Before you use the can, you should shake it well. The manufacturer has labeled the formula for use as both a surface spray and a spot treatment for problem areas.

If you have a place you know is infested with German roaches, you can layer some extra pesticide there. If you just have areas you’re trying to keep clean, you can use a wide sweeping motion with the aerosol can. Try to keep from breathing the solution into your lungs.

One of the advantages of this treatment is that it sprays as a visible foam that then dissipates into surfaces. You don’t need to wonder where the formula has landed, because it’s immediately obvious to the eyes. There’s no chance of missing corners or small spots.

In addition, the can comes with an extension tube that allows you to maneuver the spray into difficult-to-reach areas. Whether you’re sealing a crack behind the furniture or reaching up to the ceiling, the tube has you covered. It makes the application of the spray much simpler and less messy.

The formula has been approved for use in a number of different areas. You can use it in residential, industrial, and commercial places. As long as you follow the label’s instructions for use, the formula can get rid of insects and cockroaches in cafeterias, bakeries, candy plants, kitchens, food processing facilities, restaurants, meat and produce canneries, and other food handling environments.

In addition, it’s safe enough for use in hospitals, locker rooms, and schools. Because it’s safe to use around animals as directed, you can get rid of roaches in kennels, pet stores, and shelters. The manufacturer has labeled the insecticide for use on transportation systems like planes and trains as well, since the chemicals don’t tend to impede air quality as long as they’re used properly.

The aerosol begins working upon contact with the insects. If the insects walk across a surface that’s been treated, they will become contaminated by the insecticide. They will carry the active ingredient to their nests and other hideaways, infecting the larvae and nymphs. Whatever eggs have been laid won’t hatch, and the nymphs and larvae will die before reaching maturity. The aerosol spray has been approved for use in kitchen pest control methods.

Among the insects that the insecticide has been proven to kill are cockroaches, stored product pests, drain flies, fruit flies, and bed bugs. You can use this spray in conjunction with roach baits to encourage the roaches to feed more and reduce roach resistance to different baits.

One can is capable of treating up to 1,200 square feet of surface area. It’s important to note that this is not a repellent formulation. While it will kill the roaches, it won’t keep them away through scent or feel.

#2. MGK Vendetta Plus Cockroach Gel Bait

Check Price

This is another type of IGR bait offered by MGK. Rather than coming in an aerosol spray can, this bait comes in four syringes, each of which holds thirty milliliters of bait. You can create traps and set them in the places that the cockroaches tend to frequent. When the food is taken back to the nest, the insecticide kills more of the cockroaches.

Unlike many of the other formulas on the market, the Vendetta Plus is specifically created to kill many types of cockroaches, including German ones. German cockroaches are well-known for being some of the hardest pests to kill. Insecticides that handle American and other cockroach species can sometimes leave German cockroach populations unscathed.

But that’s not the case with this bait. It attracts German cockroaches that are both averse to bait and attracted to it. Like other IGR baits, this option reduces reproduction and therefore reduces the overall population of German cockroaches in your home.

This formula is specifically designed to target cockroaches. It will kill German, American, and brown-banded roaches, but it might not attract or kill other household pests like ants and fruit flies. When tracked back to the nest, the bait will continue to kill any cockroaches hiding where you can’t see them.

The kit comes with NyGuard IGR insecticide, which reduces an overall cockroach population and relieves you from the burden of an expanding population. In studies, the baits have proven effective on roaches with a wide variety of different dietary habits. There are also no common allergens like wheat, fish, tree nuts, dairy, shellfish, or peanuts. The bait is clean and odorless.

Some cockroach baits become runny or thin under high heating conditions. This one doesn’t, which means you don’t have to worry so much about where you store it. That also makes it good for people who live in areas with high temperatures. The syringes are easy to handle, and the bait dispenses easily and smoothly.

The syringes are designed to fit in standard bait guns, allowing you to easily bait your traps. They can also be used in both food and non-food areas. That includes areas where you store food, as well as areas like restaurants and food processing plants.

#3. Control Solutions Martin’s I. G. Regulator

This is another IGR insecticide on the market. It functions through a solution made up of 1.3 percent pyridine, which helps to control cockroach populations. Like the other options on the list, this regulator has been proven effective against German cockroach populations.

As long as you follow the instructions on the label, the regulator has been labeled for use in food and non-food warehouses, food serving areas, kennels, dog houses, furniture, and other areas involving food or pets.

There’s just four ounces of solution in each bottle. At a first glance, it might look like the least amount of formula on the list. But every ounce of solution is meant to be dissolved in a gallon of water. In total, you’re getting four gallons’ worth of insecticide to control your cockroach population.

Final Thoughts

Any kind of IGR insecticide can help control your insect population. In addition to killing the insects that already exist, the chemicals can interfere with the growth and reproductive cycle to keep new infestations from forming. However, German roaches are immune or resistant to a number of the most common pesticides on the market today. For this reason, it’s important to look for IGR products that are specifically formulated to target German roaches.

The Zoecon regulator is a great choice if you want a spray can that has a full sixteen ounces of insecticide inside. This can comes with more volume than any of the other options on the market. However, you might not be as controlled with the application as you would be with an option that uses a dropper. The manufacturer has labeled this product for use in most areas, including areas that have animals and handle food, provided that the label’s instructions are followed. Make sure you shake the can well before using it.

The MGK Vendetta kit is a good choice if you want a cockroach bait that comes with syringes instead of spray. Each of the syringes can hold thirty milliliters of the bait. Since there isn’t an aerosol spray to this method, you don’t have to worry about chemicals being breathed into your lungs. You can be very precise about where you place the baits. MGK has labeled this product for use in indoor spaces and food handling areas. It’s a bait that can attract many kinds of cockroaches and other insects, including German cockroaches.

Control Solutions has created an insect growth regulator that can be used in a variety of areas. In addition to being safe for use in residential and commercial spaces, the insecticide can also be used in both food handing and non-food areas. You can even use it in doghouses and kennels as long as you follow the label instructions. There are four ounces in a package, but each ounce is diluted in a gallon of water, meaning that the solution will last you a long time.
