Where do cockroaches live?

These creepy crawling pests are often associated with garbage, dirty kitchens, and filth. They are also know for spreading a range of diseases and triggering asthma and other allergies.

Keeping a clean house is useful and very important in order to reduce food sources used by cockroaches, but regardless of how clean your house is they may still get inside and cause an infestation.

A cockroach can enter your home by catching a ride on items brought inside, or via open doors and windows, gaps in the home’s exterior, and even water drains and sewer pipes.

Usually, you don’t realize you have cockroaches until you see them crawling around our homes and businesses, but have you ever stopped to wonder where these crawling insects live?

Common types of cockroaches

In order to find where cockroaches live, we first must understand the type of cockroach we are dealing with. There are three main species of cockroaches which can be found in our homes and businesses are:

  1. American cockroach (Periplaneta Americana)
  2. Oriental cockroach (Blatta orientalis)
  3. German cockroach (Blatella germanica)

American cockroaches

American cockroaches prefer to live in warm environments. Because it is warm, they prefer the outdoors and can often be found in and around drains, sewer systems, garbage bins, trees and wood piles.

Oriental cockroaches

Like the American cockroach, the Oriental cockroach prefers the warm outdoors. However, they’re know too shy away from the light and seek out dark, moist spaces such as mulch pits, leaf piles, and under rocks and stones.

German cockroaches

German cockroaches prefer the indoors and will live in areas which are warm and humid. The kitchen or a bathroom are prime locations, but it isn’t uncommon to find in other parts of the home if food and moisture are available.

Where do look?

Think about where you keep your trash when you throw it away … is it in a garbage can close to the house? In the garage? Because cockroaches prefer food and warmth, they’ll often move into kitchens and bathrooms. You can find them:

  • Inside cabinets and under sinks
  • Behind refrigerators and under stoves
  • Near food prep areas
  • Along floor base boards and corners

Outside, cockroaches are often found in moist, shady areas under decks and places where plumbing and sewer leaks. You’ll also find the:

  • Under brush piles and mulch
  • Crawl spaces
  • Dumpsters & Garbage cans
  • Hollow trees and fallen logs
  • Wood piles
  • Inside storage sheds

Cockroach control:


The best do-it-yourself preventive measure for keeping cockroaches out of your home or business is to keep it clean. Review the ‘inside’ and ‘outside’ target areas mentioned in this blog and keep those areas clean of food debris. Dirty dishes and garbage also attract cockroaches so clean those dishes before putting them in the dishwasher to site and take the garbage out before it gets rank. Here are some more prevention tips:

  • Store foods in airtight containers
  • Empty bins regularly
  • Clean up any and all food and drink spillages
  • Rinse cans, bottles and plastics before recycling
  • Seal all potential entry points with expanding foam


Once you see a cockroach, you most likely have a bigger problem. Where there’s one, there are always more. Removal and remediation of cockroaches can be very difficult, especially if you are trying to do it on your own. There are many pesticides and baits for cockroaches, but the chemicals used may not be safe or effective for inexperienced users.

Regardless of whether you have one cockroach or a thousand, removal is not a one-time solution. Cockroaches multiply quickly. Timing is everything. Sigma’s Quarterly Pest Control Service provides a continuing cycle of protection, implementation, and monitoring.

Signs of Cockroach Infestation

How do I know if I have a cockroach infestation?

The most obvious sign you have a roach problem is if you see one. Your home is an ideal breeding ground for certain pest species of cockroaches. With plenty of food, warmth, water and nesting sites, they can remain active all year round.

Cockroaches are mostly nocturnal, preferring to stay hidden from view and coming out to feed at night. Cockroaches are attracted to all types of food available in your home. They will eat just about anything including food, paper, packaging, plastics and fabrics, and animal matter.

If you spot roaches during the daytime, it can mean the infestation has been going on for some time or that it has progressed to the point where immediate action must be taken

Where to look

Roaches eat just about everything they come across, which in return produces a considerable amount of roach droppings. Cockroach droppings will be visible during an infestation. Small roaches produce droppings that resemble coffee grounds or black pepper, while larger roaches expel cylindrical droppings. The quantity of visible droppings is usually a good indicator of the level of infestation.

Roaches can produce a pungent, musty odor that gets worse the longer the infestation goes on. The smell is usually the result of a large number of roaches, alive and dead, leaving behind droppings and from decomposition. Roach odors linger in the air and can even affect the taste of food.

Roaches are aggressive breeders. They don’t lay singular eggs – they produce oothecae. Oothecae are oblong, brown casings that house many eggs. When roach eggs hatch, the casings are left behind, providing evidence that roaches have invaded your home or business.

What to look for

Look in cupboards and cabinets, in pantries, and along the floor baseboards. In addition, roaches like to hide under sinks and behind dishwashers. Where there is a plumbing fixture, there is a hiding place for cockroaches. Even smaller kitchen appliances like microwaves, coffee makers, toasters and blenders provide shelter for cockroaches.

Look in the back most part of the bathroom cabinets (especially if they are full of soaps and toiletry products) or medicine cabinets. Check plumbing behind sinks, baths and toilets, anywhere they can hide in sheltered dark spaces with access to water. Remember, cockroaches will eat just about anything. That includes soap residue, toilet paper and tissues – even shed skin cells and hair.

Look along the base and corner joints of walls, where the foundation wall meets the floor, and any gaps cockroaches could squeeze through. Cockroaches will hide in and eat cardboard and newspapers which makes boxes and piles of paper excellent places to hide.

How to get rid of an infestation?

You looked, you saw, and you have cockroaches. Now what do you do?

The Do-It-Yourself method would be to clean, clean, and clean some more. That helps remove the food source, but it doesn’t remove the cockroach. You can seal cracks and holes, and fix water leaks, but remember they are already in your home. You need to kill the cockroach!

Cockroaches: Know the facts, how to identify, and how to take control

These common invaders of homes can measure up to more than fifty millimeters or two inches long. The tropical species of cockroaches are typically larger than other kinds of species. Some cockroaches have wings but most are not able to fly for extended periods of time, and all have two antennae and six legs.

While many people assume that cockroach infestations occur because of a lack of cleanliness in the home or poor housekeeping, these insects can enter households by latching onto items brought into the home. Cockroaches can also enter homes through gaps and cracks in the exteriors of homes and also can enter via sewer pipes or drains.


People often blame a cockroach problem on poor housekeeping. While cleaning floors, kitchens, and bathrooms is useful and very important to reduce food sources used by cockroaches, they may get inside and cause an infestation for other reasons. These pests can hitch a ride on infested items brought inside, get indoors via cracks and gaps in the home’s exterior, enter through drains or sewer pipes and a few species of cockroaches can fly inside when attracted to lights.

In terms of how serious cockroach infestation can be, it is important to note that they are both common and difficult to get rid of. The main reasons these infestations are difficult to get rid of include the fact that they hide in an array of areas, reproduce quickly, and potentially could become pesticide resistant. These insects can transfer E. Coli or Salmonella to food and being exposed to dead cockroaches or their feces can cause asthma or allergies.
