Our home remedies for cockroaches are also cheap, safe for pets and will quickly kill roaches and their eggs. They will also tell you how to prevent cockroaches at home from ever entering in the first place.
Signs of a Cockroach infestation
Visible roaches – If you spot a roach, it is almost certain that you have a cockroach infestation. They breed so fast that the likelihood that this is a solitary individual is near zero.
Musty odor – a severe roach infestation will lead to a pungent almost ‘rotting’ smell in and around your home. The smell is particularly strong in humid climates.
Egg casings – Where roaches like to hide, they often leave behind the shell casing for their eggs. However, if their food source becomes scarce, ironically roaches will ‘clean up’ by eating the egg shells.
Cockroach feces – Roach feces can often be found behind units or in cupboards etc. The feces look similar to coffee grounds and as is the case with roach egg casing, are often consumed when food is scarce.
Dead roaches – With any large insect population, dead individuals will soon become apparent. As with egg casings, and feces, roaches will eat the dead bodies when food is scarce.
Scratching sounds – Roaches are more active at night and with the background noise reduced, you can often hear them scuttling around.
Stomach upsets – If you or your children experience perpetual upset stomachs and diarrhea, this may also be a sign of a roach infestation. The roaches carry a cocktail of harmful bacteria that they will leave behind on kitchen work surfaces, making your family ill.
How to prevent cockroaches
It goes without saying that prevention is better than cure.
As with any living creature, the cockroach will breed and multiply according to its environment.
If you want to know how to prevent cockroaches at home, then you need to think what attracts cockroaches: water, food, and shelter. Cockroaches like damp and humidity, like to hide in tight spaces and will eat almost anything.
These cockroach prevention home remedies will stop roaches from entering the home.
First of all, you need to make sure your house is free from damp and mold.
If there is one thing what attracts cockroaches, it is damp. Cockroaches use a waxy surface on their exoskeleton to help prevent moisture loss but still need a steady supply of water.
They can get water from their food but they will congregate in any moist and enclosed area to guarantee their supply. You must check all pipes, small leaks, and broken drains.
Cold water pipes will attract condensation in warm weather which is sufficient to sustain the roaches. Consider insulating your pipes if this is the case.
If you want to know what do roaches eat, they will eat almost any organic matter. Getting rid of pest food sources is essential. While a home may appear superficially clean, a cockroach will have a totally different viewpoint.
Pet hair, crumbs, grease spots, dirty clothes and dead insects are all staple fare for the roach.
Juveniles will gorge on the feces of adults and when food is scarce, adults will eat their young and egg cases.
It goes without saying that all food must be stored in sealed plastic or glass containers. Nothing must be left open overnight.
If you have cockroaches you must not just clean, but conduct the deepest clean you can imagine. Clean inside cabinets, behind fridges, under units.
Wipe down everything to eliminate accumulated grease.
The final cockroach prevention home remedy is to find out where do roaches hide.
Roaches hide in cracks and dark crevices during the day and their slender shape allows them to squeeze into the tightest of spaces.
Indeed where roaches like to hide most is in tight spaces rather than open living quarters. They will tend to seek out organic material such as paper and wood rather than metal surfaces.
Roaches will also seek warmth, which is why they like our homes so much. You will often find roaches hiding within electrical units, warmed by electrical motors.
Pay close attention to condenser units where there is a steady water supply as well as warmth.
Eliminate points of entry and debris around your property. Use caulk and cement to repair/fill cracks and crevices
Once you have dealt with the shelter, food and water supply of your roach infestation, you will need to turn your attention to the roaches themselves that are still alive.
