What Eats Bed Bugs? Natural Predators Explained (2026)

✅ Reviewed by our prevention editors • Updated June 2026 • 11 min read

It is natural to wonder whether nature offers a solution to bed bugs: what eats bed bugs? A few creatures do prey on bed bugs — certain spiders, ants, some other insects, and mites are among the things that may eat them — but here is the crucial point: natural predators are not a viable or reliable way to control a bed bug infestation. You cannot count on predators to solve your problem, and inviting other pests into your home would only trade one problem for another.

So while the question is interesting, the practical answer is that predators will not save you. Bed bugs hide so well, reproduce so quickly, and are protected enough (especially their eggs) that no realistic predator presence in a home can keep up with or eliminate an infestation. Real treatment — heat, encasements, interceptors, thorough methods, and professional help — is what works.

In this guide you will learn what eats bed bugs, why natural predators are not a solution, why you should not rely on or introduce them, and what actually works instead. We will use clear tables and finish with a printable checklist. 💚

What Eats Bed Bugs? Quick Answer

The quick answer is that some creatures do prey on bed bugs — certain spiders, ants, some other insects, and certain mites are among the things that may eat them — but natural predators are not a viable way to control or eliminate a bed bug infestation. Bed bugs hide too well, reproduce too quickly, and have protected eggs, so no realistic predator presence in a home keeps up with an infestation. And inviting other pests in to eat bed bugs would only create a new pest problem.

So while it is interesting that bed bugs have predators, the practical takeaway is that you cannot rely on nature to solve a bed bug problem. There is no natural-predator shortcut. What actually works is proven treatment — heat, vacuuming, steam, encasements, interceptors, thoroughness and follow-up, and professional help for established infestations. Predators are a curiosity, not a control method. Our guide on how to get rid of bed bugs covers what works.

Some creatures (certain spiders, ants, mites, and others) may eat bed bugs, but natural predators are not a reliable solution. Bed bugs hide and reproduce too well, and inviting other pests just trades problems. Use proven treatment.

Creatures That May Prey on Bed Bugs

Several creatures are known or thought to prey on bed bugs to some degree. Certain spiders may catch and eat bed bugs that wander into their webs or paths. Some ants and other predatory insects can attack bed bugs. Certain predatory mites and other small arthropods are also among the things that may feed on bed bugs or their eggs. So bed bugs are not without natural enemies.

However, the existence of these predators does not translate into meaningful control in a home setting. These creatures do not specifically hunt down bed bugs in the protected harborage where bed bugs hide, nor do they exist in homes in numbers or behavior that could eliminate an infestation. Their predation on bed bugs is incidental and limited, not a systematic clearing of an infestation.

So while it is true that things eat bed bugs, this is more of a biological curiosity than a practical tool. The predators are real but ineffective as a control method in your home. Knowing what may eat bed bugs is interesting, but it does not give you a way to solve the problem. Our guide on other bugs you might encounter covers some of these creatures.

Why Predators Are Not a Solution

Natural predators are not a solution for several clear reasons. First, bed bugs hide in protected, inaccessible spots — deep in seams, cracks, and crevices — where predators do not effectively reach them. The bugs spend most of their time tucked away, out of reach of any predator that might be in the home. So predators simply cannot get at most of the infestation.

Second, no predator exists in a typical home in the numbers or with the behavior needed to keep up with a bed bug infestation, especially one that is reproducing. A few incidental predators cannot match a growing population of well-hidden bugs. Third, relying on predators would mean tolerating those other creatures in your home, which is its own problem (more on that below).

So the combination of bed bugs hiding ability, reproduction, and protected eggs, plus the limited and incidental nature of any predation, means predators cannot control an infestation. There is no realistic scenario where natural predators clear your bed bugs. This is why proven treatment, not nature, is the answer. Our guide on why bed bugs are so hard to get rid of covers their resilience.

Bed Bugs Reproduce and Hide Too Well

Two of bed bugs defining traits — prolific reproduction and excellent hiding — are exactly why predators cannot keep up. Bed bugs reproduce steadily, with each female laying many eggs over time, so a population can compound faster than incidental predation could reduce it. Even if a predator ate some bugs, the population would keep growing from the many it could not reach.

Their hiding ability compounds this: bed bugs tuck into protected harborage where predators do not effectively hunt, so the bulk of the population is simply inaccessible to any predator. A predator might catch the occasional bug out in the open, but the hidden majority — and the eggs — remain untouched. So both reproduction and hiding work against any predator-based control.

This is the same reason bed bugs are hard to eliminate by any incomplete method: they hide and they multiply. Predators, being incidental and unable to reach the harborage, are even less effective than a thorough human treatment that targets the hiding spots. The bugs traits that frustrate treatment also defeat predators. Our guide on how fast bed bugs multiply covers their reproduction.

Possible Predators at a Glance

Possible Predator	Reality as a Control Method
Certain spiders	Incidental; cannot reach harborage
Some ants and predatory insects	Limited; not reliable control
Certain predatory mites	Not a practical home solution
Other small arthropods	Incidental predation at best
Any predator in numbers	Would be its own pest problem

Bed bugs have predators, but none is a viable way to control an infestation in your home.

Do Not Invite Other Pests

An important warning: do not try to use other pests to control bed bugs by inviting them into your home. Even if a creature eats bed bugs, deliberately introducing or tolerating spiders, ants, or other pests to hunt bed bugs would simply trade one pest problem for another — and the new pests would not even solve the bed bug problem (since they cannot reach the harborage or keep up). You would end up with bed bugs and another infestation.

This is a tempting but counterproductive idea. The predators that eat bed bugs are pests you would otherwise want to keep out of your home, and encouraging them creates new issues without resolving the original one. There is no version of this strategy that ends well — it adds problems rather than removing them.

So resist any notion of using predators as pest control in your home. The right approach is to eliminate the bed bugs with proven methods and keep other pests out too. Do not trade your bed bug problem for a spider or ant problem. Nature does not offer a clean swap here. Our guide on choosing safe, effective methods covers proper control.

Why You Cannot Rely on Nature

The broader lesson is that you cannot rely on nature to solve a bed bug problem. Bed bugs are highly successful precisely because they evade their natural enemies — hiding in human dwellings, in protected spots, close to a reliable food source — which is part of why they have spread so widely despite having predators. Their lifestyle is built around avoiding the very predation people hope might save them.

So waiting or hoping for natural predators to take care of an infestation is futile; the infestation will grow while you wait. This is similar to other passive hopes that do not work — like waiting for bed bugs to starve out or for cold weather to kill them — in that bed bugs resilience defeats the passive approach. Nature will not do the job for you.

The reliable path is active, proven treatment that targets the bugs where they hide and accounts for their reproduction and eggs. Predators, like other passive hopes, are not part of an effective strategy. Recognizing that you cannot rely on nature directs you to the methods that actually work. Our guide on whether bed bugs go away on their own covers why passive approaches fail.

The Egg Problem for Predators

Bed bug eggs pose a particular problem for any predator-based hope. The eggs are tiny, laid in protected, hidden spots, and resistant — the same traits that make them resist many treatments also put them out of reach of predators. So even if a predator ate some adult bugs, the protected eggs would hatch and continue the infestation, just as they do after an incomplete treatment.

This egg factor means that no predator could realistically eliminate an infestation, because it could not reach and destroy the hidden eggs. The next generation would keep emerging regardless of any predation on the visible bugs. This is the same reason that methods missing eggs fail — and predators, being even less able to reach protected eggs, fail all the more.

So the eggs are yet another reason natural predators cannot solve a bed bug problem. Effective treatment must reach or account for the eggs (via heat, encasements, follow-up), which predators cannot do. The protected eggs defeat the predator hope just as they defeat incomplete treatments. Our guide on bed bug eggs explains their protected resilience.

What Actually Works Instead

Since nature will not solve bed bugs, here is what actually works: proven, active treatment. Heat is a cornerstone — high-heat laundering and drying for items, steam for harborage, and professional heat treatment for whole rooms — because it kills bugs and eggs. Vacuuming physically removes bugs, encasements seal the mattress and box spring, and interceptors catch and monitor. Thoroughness across all the hiding spots, plus follow-up to catch hatchlings, is what eliminates an infestation.

For established or stubborn infestations, professional treatment is the most reliable route, using comprehensive methods designed to reach the whole infestation. Throughout, monitoring confirms progress and success. None of this relies on predators or nature; it relies on methods matched to bed bug biology — reaching the harborage, killing the eggs, and following up.

So channel your energy into these proven methods rather than hoping predators will help. They target the bugs where they hide, handle the eggs, and account for reproduction — the things predators cannot do. Active treatment is the real solution. Our guide on the DIY treatment plan covers the proven approach.

Predators vs Proven Methods

Natural Predators	Proven Methods
Cannot reach harborage	Heat and steam reach hiding spots
Cannot keep up with reproduction	Thorough treatment plus follow-up
Cannot reach protected eggs	Heat kills eggs; follow-up catches hatchlings
Would be their own pest problem	No new pests introduced
Not a reliable solution	Reliable when done thoroughly

Protecting and Monitoring Your Bed

Instead of relying on predators, protect and monitor your bed with proven tools. The two most valuable are interceptors and an encasement. Interceptors placed under the bed and furniture legs catch crawling bugs and reveal activity, while an encasement seals your mattress and box spring so bugs cannot hide there. You can view interceptor options on Amazon and protect the bed with a mattress encasement (see options on Amazon).

A flashlight makes inspections effective, revealing bugs and evidence in seams and cracks — the harborage predators cannot reach. A detection flashlight (view on Amazon) helps you target the hiding spots that matter.

These tools, combined with heat and thorough treatment, do what predators cannot — reach the harborage, kill eggs, and monitor for success. Rely on proven methods, not nature. Our complete prevention guide ties it together.

Common Mistakes (and Fixes)

• Mistake: Hoping predators will solve the problem. Fix: they cannot — use proven, active treatment.
• Mistake: Inviting or tolerating other pests to eat bed bugs. Fix: never — it trades one pest for another without solving it.
• Mistake: Waiting for nature to take its course. Fix: bed bugs evade predators and multiply — act with treatment.
• Mistake: Ignoring eggs. Fix: predators cannot reach eggs; use heat and follow-up that can.
• Mistake: Treating predators as a real method. Fix: they are a curiosity, not control — rely on proven methods.

Expert Pro Tips

• Predators are a curiosity, not a cure. They cannot reach the harborage or keep up.
• Never invite other pests. It only adds a problem.
• Do not wait on nature. Bed bugs evade predators and multiply — act.
• Use methods that reach eggs. Heat and follow-up do what predators cannot.

Yes, a few creatures eat bed bugs — but none can clear an infestation, and inviting them in just adds a pest. Bed bugs thrive precisely by dodging their predators, so the solution is active treatment, not nature.

The traded problem. Tom considered tolerating other pests to eat the bed bugs, then realized he would just have two problems. He kept other pests out and treated the bed bugs properly.

The proven path. Rather than relying on predators, Dana used heat, vacuuming, encasements, and follow-up, reaching the harborage and eggs that no predator could — and eliminated the infestation.

Frequently Asked Questions

What eats bed bugs?

Some creatures prey on bed bugs to a degree — certain spiders, ants, some other insects, and certain mites — but their predation is incidental and limited. None is a viable way to control or eliminate a bed bug infestation.

Can natural predators get rid of bed bugs?

No. Bed bugs hide in protected spots predators cannot reach, reproduce faster than incidental predation could reduce, and have protected eggs. No realistic predator presence in a home can eliminate an infestation. Use proven treatment instead.

Should I use spiders or other bugs to eat bed bugs?

No. Inviting or tolerating other pests to hunt bed bugs would only create a new pest problem without solving the bed bugs (the predators cannot reach the harborage). You would end up with two problems. Keep other pests out and treat the bed bugs.

Why cannot predators handle bed bug eggs?

Bed bug eggs are tiny, protected, and hidden, so they are out of reach of predators — just as they resist many treatments. Surviving eggs hatch and continue the infestation, so predators could not eliminate it even if they ate some adults.

Do bed bugs have any natural enemies in the home?

There may be incidental predators present, but they have no meaningful effect on an infestation, since bed bugs hide where predators do not hunt and reproduce faster than any predation could counter. Bed bugs thrive by evading their enemies.

What actually gets rid of bed bugs?

Proven, active treatment: heat (laundering, steam, professional heat), vacuuming, encasements, interceptors, thoroughness across hiding spots, and follow-up to catch hatchlings, plus professional help for established infestations. Not predators or nature.

If Not Predators, What Are Bed Bugs Weaknesses?

If natural predators cannot beat bed bugs, it is worth asking what bed bugs real weaknesses actually are — because they do have exploitable ones, just not predation. The biggest is heat: bed bugs and their eggs cannot survive sustained high temperatures, which is why heat methods (high-heat drying, steam, professional heat treatment) are so effective. Heat reaches into the harborage and kills all life stages, doing what predators never could.

Another weakness is their inability to climb very smooth surfaces, which is exactly what interceptors exploit — the bugs fall into the slick cups and cannot climb out, so they are trapped and monitored. And because bed bugs must crawl (they cannot fly or jump) and stay near the host, isolating and protecting the bed cuts off their access. These are real, reliable vulnerabilities you can target.

So rather than hoping a predator will help, target the weaknesses that actually work against bed bugs: heat to kill them and their eggs, smooth-surfaced interceptors to trap them, bed isolation to block their crawl, and thorough treatment with follow-up to overcome their reproduction. These exploit the bugs genuine vulnerabilities far more effectively than any predator could. The path to beating bed bugs is through their real weaknesses, not their natural enemies. Our guide on what actually kills bed bugs covers heat and these vulnerabilities.

Final Verdict + Checklist

What eats bed bugs? A few creatures — certain spiders, ants, mites, and others — may prey on them, but natural predators are not a solution. Bed bugs hide where predators cannot reach, reproduce faster than incidental predation could counter, and have protected eggs, so no realistic predator presence clears an infestation — and inviting other pests in just trades problems. Do not rely on nature or wait it out. Use proven, active treatment: heat, vacuuming, steam, encasements, interceptors, thoroughness, and follow-up, with professional help for established cases. The predators are a curiosity; treatment is the cure.
