How Do You Know if You Have a Roach Infestation?


Cockroaches deposit their eggs in dark places, such as behind appliances or under sinks.

These eggs are never visible to the human eye.

They are a sign you have an infestation on your hands.

Smear Marks and Smudges

Keep an eye out for cockroach markings on walls and furniture; these markings are typically caused by grease or oil left behind by roaches as they move around your home.

They leave brown marks on wood that don’t look good and dark marks on wallpaper or plaster walls that don’t look good either.


Cockroaches will eat almost anything organic, including paper, fabric, cardboard, and even other insects.

So, damage to food packaging is a sign that you have an infestation in your home or business.

Other major symptoms include damage to woodwork, baseboards, and moldings.

Unusual Odor

When an infestation has been present for some time, you will smell a musty odor coming from your cupboards and other storage areas.

The musty odor taints your food and belongings and can linger for months.

Cockroach Droppings

Rodent or insect droppings are a sign that you have unwelcome guests in your home.

Small cockroaches leave their waste behind as they move around. Larger species usually leave their waste in hidden places, like under appliances and in cabinets.

Roaches with larger droppings usually mean you have a larger population to contend with.

How to Get Rid of a Heavy Roach Infestation

Once you’ve confirmed that you have roaches, the next question is how to get rid of a heavy roach infestation.

There are several anti-cockroach solutions on the commercial market today. However, these can be expensive and may pose a danger to children and pets if not used properly.

Before you apply, you should thoroughly read all labels and follow the manufacturer’s instructions.

You don’t want to harm your home’s occupants with the wrong product.

Boric Acid

If you want to do it the natural way, boric acid is a non-toxic product that can be safely applied to areas where you have seen signs of roaches.

To produce a dough, combine 1 cup of boric acid with 1 cup of water and stir until it becomes a thick paste.

Place these dough balls around your kitchen and bathroom, as well as in your cupboards and other storage areas.

Roaches can’t stand the flour-like consistency of the boric acid; it will kill them without harming you or other inhabitants of your home.

Keep in mind that if you miss a hiding place, they will simply move to another location, so you’ll want to monitor these areas closely to ensure maximum effectiveness.

Liquid Concentrate Sprays

There is a liquid concentration that can be sprayed on roach-infested areas to kill them in two hours.

You may also use this solution as a preventative measure to protect new areas of your home from attack.

This is an extremely effective method for killing roaches in cracks and crevices where it is difficult for other insecticides to reach.

Glue Traps

You can catch and kill a few roaches in your home by getting glue traps from your local home improvement store.

They use a scent to attract roaches, which then walk into the trap and get stuck on the surface by the glue.

These gadgets may provide benefits when used on small infestations, but they can become a nuisance if used in large quantities.

Clean Your Home

It may sound obvious, but cleaning your floors, countertops, and surfaces is an important way to keep your home free of pests like cockroaches.

Roaches are drawn to dirt and garbage, so removing these items will stop infestations before they begin.

Wash your dishes as soon as you can after using them and wipe your countertops down regularly with a disinfectant wipe.

Remember, cleanliness is a deterrent to pests such as roaches.

Regularly mop and vacuum, clean oil and grease from floors and countertops, and clean under appliances on a regular basis to keep your home as pest-free as possible.

Chemical Baits

Using store-bought roach baits is an effective way to kill an entire colony quickly and safely.

These pesticides are sprayed in regions where you see signs of activity—usually around baseboards, in corners, or behind appliances—and they work immediately by causing internal bleeding and death of the insect.

The insects subsequently perish from the poison and die within a couple of days.

Other roaches eat them, and the poison spreads through the colony. Within a few days, everyone in the colony is dead.
