How to Prevent an Infestation and Remove German Cockroaches?

By following the steps mentioned below, you can successfully eliminate and prevent a German cockroach infestation:

  • Identify the Problem

    You can only come up with a solution after identifying the real problem. Therefore, it is essential to confirm what type of pest you are dealing with, inspect your home for any roach activities, and identify their hideouts, access points, and nests. Some of the main signs of an infestation is spotting a live cockroach, finding their droppings, dead roaches, or shed skin.

  • Use Baits

    Cockroach Monitor StationsOnce you have identified the type of cockroach you are dealing with and their hideouts, carefully place multiple baits around your home, especially in your kitchen, bathroom, cabinets, etc., with a gap of 6 feet between each bait for a higher success rate of catching them by at least one bait.

    While looking for food and water, the cockroach would go for the bait and then take it back to their nest that should help kill the infestation slowly but efficiently.

  • Use a Spray

    If you do not have the patience to wait for the cockroach to go to the bait, you can spray them with an over-the-counter cockroach killing spray to get rid of them instantly. However, you may need to keep spraying them for a few days until you are sure you have got them all. Because even if a few remain, they could soon multiply, and you would be dealing with another cockroach infestation.

  • Using Baking Soda

    For this method, you would need to mix sugar with baking soda and keep it out on the table as bait, along with a bowl of water nearby. This is an effective way to get rid of cockroaches as the sugar attracts the cockroach while the baking soda, when mixed with water, would cause their stomach to explode, killing them instantly.

  • Make a Trap

    All you need is a bit of petroleum jelly, a bowl, and food as bait. Just add the food to the bowl and grease the insides of the bowl with petroleum jelly. The food will attract the cockroach to enter the bowl, while the petroleum jelly would make it impossible for the cockroach to escape. All you need to do is effectively dispose of the bowl after the cockroach is trapped.

  • Determine If You Need More Insecticide

    Although baits and sprays are enough to help you control the infestation, sometimes it is just not enough if the infestation is too far gone. In such situations, you can use more insecticides to control the infestation. Using insect growth regulators, diatomaceous earth, boric acid, and other stronger insecticides should help you get rid of the infestation.
