Limitations for Ants in Controlling Bed Bugs

You have heard instances where natural predators have been successfully used to eradicate pest infestation. While some ants are natural predators for bed bugs, they cannot be relied on because of the following limitations:

1. Bed Bugs are Elusive

Bed bugs are quite elusive and will hide in very narrow and dark places where there’s minimal disturbance. Unlike ants, bed bugs have a flat body that allows them to fit and hide in small cracks.

In addition, bed bugs come out to feed at night, meaning ants have little chances of getting them.

2. Ants are Pesky Pests

Similar to bed bugs, ants are pesky pests you don’t want to have around your premises. Although they don’t feed on people, they are much irritating in several other ways. Such nuisance may include:

  • Damaging wooden furniture and structures.
  • Foraging on your food.
  • Some have a venomous sting which may cause intense pain and anaphylaxis in some people.
  • They are nagging when they crawl around the house.

In addition, these creatures reproduce rapidly, meaning they can easily become an infestation. Plus they live in hidden places, making it hard to eradicate.

3. They Cause Damage in Your Home

When inside your house, ants will cause unimaginable damage. One of the most disastrous ant is the carpenter ant which excavates wooden things to make nest for living and breeding.

Some ants will force themselves into tiny cracks such as in floorboards and baseboards, gradually causing those spaces to widen and lose their splendour. Similar to bed bugs, some ants hide in electronics, which may present a fire risk in your house due to short-circuit.

What’s more, damage can include even the waste they dumb out of their colony.

4. Cost of Eradicating Ants is High

The cost of eradicating ants is much higher than if you had to use DIY remedies or hire an exterminator to eradicate bed bugs. If you get ants to feed on bed bugs, they will reproduce rapidly, eventually becoming an infestation.

Therefore you’ll incur extra costs in DIY pest remedies or in hiring a professional exterminator to get rid of them.

5. Ants Might Become an Infestation

Ants find it east to colonize new areas rather than fighting for limited resources. So if you get ants to eradicate bed bugs in your house, they might split into colonies and shift in various locations.

When there’re many colonies of ants in your compound, you might end up having an infestation which is hard and costly to eradicate.

Getting Rid of Bed Bugs & Ants

Both ants and bed bugs present varying difficulties in eradicating. Thus, if you have the two infestations, you’ll need to invest in different approaches to eradicate them.

Bed bugs

The size and shape of bed bugs makes it easy to hide in very narrow crevasses, where they live and breed rapidly. This makes it difficult to completely eradicate each and every bed bug even with the best pesticide in the market.

In addition, bed bugs reproduce rapidly, up to 4 generations in twelve months. That means, a few bed bugs can become an infestation within a very short period. Plus they can stay for long without feeding.

However, with the best pest eradication strategies, it is possible to significantly reduce their numbers or eradicate completely. Bed bug treatment should entail the following:

  • Minimizing the spread by vacuuming infested things.
  • Heat treatment targeting bed bugs at all stages of their life cycle.
  • Use of the most effective pesticides in the market such as boric acid, silica gel and diatomaceous earth.
  • If the infestation is beyond your control, you should call a professional exterminator to assess and determine the correct bed bug treatment to use.


Ants are equally hard to eradicate especially due to their tendency to exist in large colonies. A single colony can have up to hundreds of thousands of ants, meaning it is hard eliminate all of them at a go.

Secondly, ants build their nests in hidden places away from human interference. Thus, it may be difficult to locate each and every hideout and kill every ant. Since ants are very industrious, there will be so many of them foraging for food outside the colony. So, even if you bombed their colony, there’ll be survivors to start and build a new colony.

However, this does not mean that it’s impossible to eradicate ants. With a proper pest control plan, it’s possible to get the job done even without the help of an expert. This may include:

  • Assessment of the extent of the infestation.
  • Use pesticides to destroy their nests and colonies.
  • Clear any trash and food debris that may attract ants to your house.
  • Create repellent barriers at any possible entry point using, talcum powder or any other effective chemical.
  • Be on the lookout for new infestations so as to act on them promptly.


While some ant species can kill and eat bed bugs, they are not a reliable method for eradicating bed bugs. Usually, ants don’t go hunting down bed bugs.

They prefer sweet food like honeydew and will only eat bed bugs to get a protein meal. In addition, most ant species are not predators. They scavenge on carcasses for their food.
