How Does It Work?

Gel bait is one of the most effective ways to eliminate cockroach infestations.

This control method is highly effective because it implements tertiary kills.

Here’s what I mean.

Gel baits turn cockroach feces into poison.

When a cockroach ingests gel bait, they don’t die right away.

Because juvenile roaches (nymphs) rely on feces to survive, the toxic wastes will kill them.

Once they die, other cockroaches that eat their bodies become poisoned too.

How To Apply It?

Gel baits are easy to apply because they come inside a syringe.

The syringe makes it easy to apply gel bait into small crevices that cockroaches hide in.

Apply gel bait to small crevices around your kitchen to ensure that you infect as many roaches as possible.

Some other great places for application include inside your cabinets, floorboards, and under your appliances.

Apply a pea-sized drop of gel bait about every two feet.

Doing so will allow the roaches easy access to the bait.

To keep track of where you place your gel bait, place it on a 2×2 inch wax paper.

The wax paper wrap will also make it easy to put bait in hard-to-treat places (e.g., within stacks of clutter).

After two weeks, wipe down or remove the wax paper and apply some more.

How It Works?

IGRs act as a final resort to kill any remaining eggs and baby cockroaches.

Since eggs, female, and baby cockroaches don’t move as often as adult cockroaches they don’t always come in contact with gel bait.

Often pregnant females and nymphs do not forage for food but depend on the feces from other adult roaches.

To prevent your cockroach infestation from growing, use insect growth regulators or IGRs.
IGRs are a useful tool that helps break the rapid life cycle of cockroaches.

To do this, IGRs mimic the juvenile hormone that naturally occurs in an insect and disrupts the nymph’s growth cycle.

As a result, IGRs prevent the normal development of baby cockroaches so they cannot produce viable eggs as adults or die during the molting process.

How To Apply?

Applying IGR packets is the easiest way to use IGR inside your apartment.

Most IGR applications require spraying.

This method is time-consuming and difficult for amateurs.

What Is The Most Effective Way To Kill Cockroaches?

Using one product is not the best way to kill all the cockroaches in your home.

The best way to do this involves attacking cockroaches using different application methods. 

To do this you will need to: 

  1. Use Glue traps to help you identify the type of cockroaches you have.
  2. Use gel bait in high traffic areas.
  3. Apply dust bait into hard to reach crevices.
  4. Use insect growth regulators to stop the reproduction cycle.

Here are the products you will need to eliminate cockroaches from your apartment.

  1. Glue Traps
  2. Gel Bait
  3. Dust Powder
  4. Insect Growth Regulators (IGR’s)

Types of Roach Killers

There are several types of roach killers you can use.

In fact, choosing one is overwhelming.

The best approach to treating cockroaches is using several different roach killers.

1. Insecticide Spray

One of the most common types of cockroach killers is sprays.

Cockroach sprays include insecticide sprays such as raid or hotshot.

Insecticide sprays are ideal because they provide instant kills and have some residual effect.

The disadvantage of insecticide sprays is that they contaminate your home with toxic chemicals.

2.Cockroach Bait

Bait is one of the most effective ways to treat cockroaches.
This is because it delivers tertiary kills.

Tertiary kills allow you to target a large number of cockroaches even if they are not eating the bait itself.

For example, the cockroach that eats the bait, any babies that eat the adult feces, and any cockroaches that eat infected cockroaches will also die.

The bait comes in two forms:

  1. Syringes
  2. Bait Stations

Bait stations are safe and easy to apply.
Simply open the box and place them where you expect cockroach activity.

Syringes are great because you can easily apply bait to small crevices and hard to reach areas.

3. Dust

Another common method of treating cockroaches is using dust. 

Two of the most common dust applications are:

  1. Diatomaceous Earth 
  2. Boric Acid

These are typically applied with a small hand pump or tube.

Use these devices to apply dust bait to high traffic areas or small crevices that are hard to reach with gel bait.

The layer of dust you apply should be very light and barely visible to the naked eye.

When cockroaches come into contact with the dust, it will either destroy their exoskeleton or they will eat it and die. 

4. Insect Growth Regulators (IGR’s)

Insect growth regulators don’t kill cockroaches in the traditional sense. 

IGR’s target baby cockroaches and eggs using hormones. 

IGRs prevent the normal development of baby cockroaches so they cannot produce viable eggs as adults or die during the molting process.

This will stop the reproduction process of any cockroaches in your home. 

IGR’s can be applied using a spray treatment or pheromone packs.
