Bed bugs are one of the most notorious pests that can invade your home and disrupt your peace of mind. They are small, reddish-brown insects that feed on the blood of humans and animals, and are notoriously difficult to get rid of. If you’re dealing with a bed bug infestation, you might be wondering what eats bed bugs and how you can get rid of them.

In this comprehensive guide, we’ll explore the various predators and natural enemies of bed bugs, as well as some effective methods for controlling their populations.

Natural Predators of Bed Bugs

While bed bugs may seem invincible, they are actually vulnerable to a number of natural predators. Here are some of the most common predators that feed on bed bugs:

1. Cockroaches

Cockroaches are one of the most common predators of bed bugs. They are attracted to the same warm, dark, and moist environments that bed bugs thrive in, and they will happily munch on any bed bugs they come across.

2. Ants

Ants are another predator that can help control bed bug populations. While they are not as effective at killing bed bugs as some other predators, they can still help to keep them in check.

3. Spiders

Spiders are natural predators of many insects, including bed bugs. They are particularly effective at catching bed bugs in their webs, and can help to keep their populations under control.

4. Mites

Mites are tiny insects that are closely related to bed bugs. While they are not predators in the traditional sense, they can still help to control bed bug populations by feeding on their eggs and nymphs.

Biological Control of Bed Bugs

In addition to natural predators, there are also a number of other biological control methods that can be used to control bed bug populations. Here are some of the most effective methods:

1. Parasitic Wasps

Parasitic wasps are a type of wasp that lay their eggs inside the bodies of other insects, including bed bugs. Once the eggs hatch, the wasp larvae feed on the host insect, effectively killing it.

2. Fungal Spores

Fungal spores can be used to control bed bug populations by infecting and killing them. The spores are usually applied as a powder, and when the bed bugs come into contact with them, they become infected and eventually die.

3. Beauveria bassiana

Beauveria bassiana is a type of fungus that can be used to control bed bug populations. It works by infecting the bed bugs with a deadly disease, which eventually kills them.

Chemical Control of Bed Bugs

While natural predators and biological control methods can be effective at controlling bed bug populations, they are not always enough to completely eliminate them. In these cases, chemical control methods may be necessary. Here are some of the most common chemical control methods for bed bugs:

1. Insecticides

Insecticides are the most common type of chemical control method for bed bugs. They work by killing the bed bugs on contact or disrupting their reproductive cycle.

2. Heat Treatment

Heat treatment is another effective way to control bed bugs. It involves raising the temperature in the infested area to a level that is lethal to bed bugs, but not harmful to humans.

3. Cold Treatment

Cold treatment involves exposing bed bugs to sub-zero temperatures in order to kill them. It is less commonly used than heat treatment, but can still be effective in certain situations.

Preventing Bed Bug Infestations

While it is important to know how to control bed bug populations once they have already infested your home, the best way to deal with bed bugs is to prevent them from entering in the first place. Here are some tips for preventing bed bug infestations:

  • Inspect second-hand furniture and clothing before bringing them into your home.
  • Seal up cracks and crevices in your home to prevent bed bugs from entering.
  • Use bed bug-proof mattress and pillow covers.
  • Regularly vacuum and clean your home to eliminate potential hiding spots for bed bugs.


While bed bugs can be a frustrating and persistent pest, there are a number of natural predators and biological and chemical control methods that can be used to control their populations. By taking steps to prevent infestations in the first place, you can avoid the need for these methods altogether. Remember to always consult with a professional pest control expert for the most effective and safe methods for dealing with bed bugs.
