Cleaning and exclusion are two more weapons you may employ to accomplish this, and both function by depriving cockroaches of essential items. This is how it works:

1. Sanitation

Walk into the kitchen with a vacuum cleaner, suction extensions, broom, scrubber, and pail, and start by pushing the fridge aside from the wall. Are there any cockroaches darting out from behind the table?

The tiny buggers should be vacuumed up. Any of it along the walls, in the nook, on the coils of the fridge, or near the motor? Allowing them to flee is not an option.

Vacuum up the wreckage – theloose powdered particles, roach corpses, egg cases, and body parts—after vacuuming up every cockroach you encounter.

To reach further into cracks and crevices, use the crevice tool, as well as your brush tool, to loosen and suck off much of the stuck-on filth.

As a pest management approach, sanitation consists of denying cockroaches of the two things they require most to stay alive: food and water. If you remove those, cockroaches will either die or flee.

Your drains have cockroaches inside them, don’t they? They didn’t most likely swim up via the sewage. They presumably came upon your drains while searching for water and decided to remain since they were wet and warm.

So get a drain plug to keep cockroaches away, repair leaking faucets, and make it a practice to clean up even the smallest drips and puddles.

Take your torch and search your under-sink regions for leakage and even moisture. Keep a towel near the shower or bathtub to absorb water at the bottom, and switch on the bathroom vent while bathing to decrease moisture quickly.

When you’re finished, pour the water underneath your dish rack and flip it on its side to allow the remainder of the water to drain out.

3. Deprive Cockroaches of Food Sources

Use trash cans having close-fitting covers and wipe them down on a regular basis to keep cockroaches out of your trash area.

Keep the area surrounding them hygienic, and dump bags away occasionally to reduce the enticing scents to cockroaches. Put all of your dry food items and ingredients inside a pair of plastic or glass jars featuring tight-fitting covers.

Keep the outside of the refrigerator clean and clear of any food stains that may become a source of food, and avoid storing foodstuff inside plastic bags. They may be chewed completely through by cockroaches.

Cockroaches feed on breadcrumbs and spillage, and while there’s no way to eliminate them totally, there are a few simple ways to minimize them.

Make a new house rule: all eating must take place inside the kitchen and/or eating zone, reducing the amount of crumbs cockroaches can discover.

If you own pets, put their food dish inside the kitchen as well—roaches love pet food! You will also need to vacuum and clean down your floors more frequently than most households. A cockroach can eat a single crumb, and they have been receiving them up to this moment.
