1. Bayer Maxforce German Cockroach Killer

Bayer Maxforce German Cockroach Killer

It’s the most effective cockroach killer out there, and Bayer Maxforce FC Magnum Cockroach German Roach Pest Control Gel Bait is the one for you. It works in two ways.

Although cockroaches don’t spread viral infections, they are a source of bacteria and can cause serious health issues. Additionally, they can cause food poisoning by wandering on unwashed dishes. This is why it is so hard to get rid of them.

What Are the Types of Cockroach Killers?

Roach killers are available in different types and variants, and each has its own unique features. Sprays are effective in hiding places, while roach motels offer a safer alternative for kids and pets.

Powders

The powder can be used anywhere, even at hard-to-reach places, to kill roaches. Pour the powder between the nests of roaches, and they are finished within minutes.

Sprays

A spray is an easy solution for kitchen safety. Sprays attack the nervous system of roaches and kill them quickly. Also, sprays are handy compared to other roach killers and can reach inaccessible places.

Roach Motels

In roach motels, roaches are enclosed in a box in which they cannot leave. They are non-toxic and safe for children.

In other motels, the roaches are attracted by poisonous substances that kill them immediately. Children and pets are not safe from it.

Roach Gel

There is something about gel that roaches can’t resist. The best thing about gels is that they don’t kill the roaches immediately, but they start acting when the roaches return to their homes. It creates a spontaneous process when roaches are killed in their habitats, and this causes the other roaches to be eaten as well.

Foggers


A fogger, also called a bug bomb, contains a poisonous gas that is used to kill roaches. When activated, foggers release a poisonous gas that penetrates inaccessible spaces, covering the entire room. They use pyrethroids, which kill the roach slowly by slowly destroying its nervous system.

If you plan to use foggers, make sure all edibles, dishes, and other utensils are covered, and leave the room for at least four hours.

Considerations Before Buying a Cockroach Killer

Effectiveness On Pests

It is always important when selecting a cockroach killer to pay attention to what pesticides it uses and on which insects it is effective. Different killing products work differently and target different insects.

Roaches have a good immunity, so roach killers use high-potency pesticides that can even harm pets and children. The glue sheets can catch every size of an insect, including rats, lizards, ants, and roaches.

Safety Factors for Pets and Children

Prior to starting any operations, ensure that you and your family are in a safe area. The gels and baits are attractive to both kids and pets due to their bright colors.

These roach killers are safe for children, but they aren’t that effective. Use them if the problem isn’t too severe.

Length Of Efficacy

It is important to understand how long the roach killer will actually work. Most roach killers will produce results for at least a month, but may take as long as 2 years to completely eradicate the roach population.

Types of bait

Generally, two types of baits are used to kill and attract roaches: Fipronil and hydramethylnon.

The poison in fipronil is poisonous and works very fast! Roaches can’t move after consuming it. It attracts roaches with sugar and kills them instantly with fipronil.

However, hydramethylnon kills insects in a slower way! Insects are attracted and lured to eat. When they finish eating, they return to their habitat, lose their nervous system slowly, and that’s it. The spontaneous process kills the whole community in your home because the killed roaches become food for other roaches, killing them as well.

What Do Professionals Use To Kill Roaches?

A high-level insecticide used by professionals to eradicate roaches is Indoxacarb, which is also available in gels. It is recommended over other insecticides due to its high potency and effectiveness.

What Kills Roaches And Their Eggs?

Boric acid kills roaches and their eggs naturally. A shower of boric acid is enough to keep roaches away for life.

Sugar and Baking Soda as a Cockroach Killer

It’s easy to attract roaches with sugar, and baking soda kills them right away. Place them near the nest and clean up the dead roaches afterward.
