Cockroaches and bed bugs are two common household pests that can cause problems for homeowners. While bed bugs are known to live in beds and other furniture, many people wonder where cockroaches live if bed bugs are already occupying those spaces. In this article, we will explore the living habits of both pests and answer some common questions about their behavior.

Cockroach Living Habits

Cockroaches are nocturnal insects that prefer to live in warm, humid environments. They are commonly found in kitchens, bathrooms, and other areas of the home where moisture is present. Cockroaches can also be found in basements, crawl spaces, and other dark areas of the home.

Cockroaches are scavengers and will eat almost anything, including food scraps, pet food, and even glue. They are known to spread bacteria and disease and can trigger allergies and asthma symptoms in some people.

Bed Bug Living Habits

Bed bugs are small, reddish-brown insects that feed on the blood of humans and animals. They are typically found in beds and other furniture, but can also be found in cracks and crevices throughout the home. Bed bugs are most active at night and can be difficult to detect because they often hide during the day.

Bed bugs do not spread disease, but their bites can cause itching and irritation. Infestations can be difficult to eradicate because bed bugs can survive for months without feeding.

Where Do Cockroaches Live if Bed Bugs Are in Beds?

If bed bugs are already living in a bed or other piece of furniture, it is still possible for cockroaches to coexist in the same space. Cockroaches may take up residence in other areas of the room or home where conditions are more suitable for their survival.

For example, if a bedroom has a bed bug infestation, cockroaches may still live in the kitchen or bathroom where moisture and food sources are more abundant. Cockroaches can also be found in other areas of the home, such as basements or crawl spaces, where they may be attracted to moisture and darkness.

It is important to note that cockroaches can spread bacteria and disease, so it is essential to take steps to eliminate infestations as soon as they are detected. This may involve using pesticides or other methods to control the population of both cockroaches and bed bugs.

How to Prevent Cockroach and Bed Bug Infestations

Preventing infestations of both cockroaches and bed bugs requires a proactive approach to cleaning and maintenance. Here are some tips for preventing these pests from taking up residence in your home:

  • Keep food stored in airtight containers and clean up spills promptly
  • Seal cracks and crevices around windows, doors, and other entry points
  • Reduce clutter in your home to eliminate hiding places for pests
  • Wash bedding regularly in hot water to kill bed bugs and their eggs
  • Vacuum regularly to remove food particles and other debris that can attract pests


How can I tell if I have a cockroach infestation?

Signs of a cockroach infestation include droppings, egg casings, and a musty odor. You may also see cockroaches scurrying across floors or walls at night.

What should I do if I find bed bugs in my home?

If you suspect you have a bed bug infestation, contact a pest control professional immediately. Bed bugs are difficult to eradicate on your own, and infestations can quickly spread throughout your home.

Are cockroaches dangerous?

Cockroaches can spread bacteria and disease and can trigger allergies and asthma symptoms in some people. It is important to take steps to eliminate infestations as soon as possible to minimize the risk of health problems.
