How to Prevent Bed Bugs

🕐 8 min read 📅 Updated July 2026
Quick Answer

To prevent bed bugs, stop them from hitchhiking in. Inspect where you sleep when traveling, keep luggage off beds and floors, run washable textiles through a hot dryer, check used furniture and clothing before bringing it home, and monitor your own bed regularly.

Preventing bed bugs is really about one thing: keeping them from being carried into your home in the first place. Bed bugs are hitchhikers — they ride in on luggage, clothing, and used items rather than wandering in from outside. Because they do not transmit disease and are not tied to how clean your home is, prevention is not about scrubbing. It is about blocking the routes they use to travel. To keep this simple, this guide uses one idea throughout: The Three-Barrier Method — keep them out, kill any hitchhikers, and deny them hiding spots.

Bed Bug Prevention

Effective bed bug prevention works by cutting off the ways these insects hitchhike into your space. Since a single mated female riding in on a bag can start a problem, the goal is to catch travelers before they settle in and to make your bed a hard place to hide. The three barriers below, drawn from public-health guidance, cover the steps that matter most.

Prevention is about travel and hiding spots — not housekeeping. Bed bugs do not spread disease.
The core prevention steps: block entry, heat-treat textiles, inspect used items, and protect the bed.

Barrier 1 — Keep Them Out

Most infestations start with an item carried across your doorway. Inspect any secondhand furniture, mattress, or clothing before it comes inside, checking seams, folds, and joints for live bugs, eggs, shed skins, or small dark spots. When you have been somewhere with a higher chance of bed bugs, treat your luggage and clothing as suspect until you have checked them.

Barrier 2 — Kill Any Hitchhikers

Heat is the simplest weapon you already own. Running dryer-safe clothing, bedding, and other textiles on a hot cycle for about 30 minutes kills bed bugs and their eggs. This is especially useful after a trip or after handling used clothing. Remember that the dryer's heat does the work, so items that cannot tolerate a hot cycle need another method.

Barrier 3 — Deny Hiding Spots

Bed bugs love the many seams and folds of a mattress and box spring. A bed bug encasement seals those hiding places so bugs cannot get in or out, which also makes any early problem far easier to see. Reducing clutter around the bed removes extra harborage, and checking your bed regularly means you catch any hitchhiker before it becomes an infestation. Knowing the early signs of bed bugs makes that monitoring far more effective.

Does Renters Insurance Cover Bed Bugs

Whether renters insurance covers bed bugs is a common question, and the general answer is no — standard renters policies usually do not cover bed bug infestations. Insurers typically treat bed bugs as a pest-control or maintenance issue rather than the kind of sudden, accidental loss that renters insurance is designed for, so infestation cleanup and treatment are commonly excluded.

That said, coverage details vary by insurer, policy, and location, and responsibility for treatment in a rental can also depend on your lease and local law. Rather than assume you are protected, read your own policy language and ask your insurance provider and landlord directly. Prevention and early detection remain your most reliable protection, since they help you avoid the cost and disruption of a full infestation in the first place.

Drying Clothes for Bed Bugs

Drying clothes for bed bugs is one of the most practical prevention steps, because bed bugs and their eggs are killed by sustained heat. After travel or after bringing home secondhand clothing, place dryer-safe items in the dryer and run them on a hot cycle for about 30 minutes. The heat — not the washing — is what destroys the bugs, so the dryer step is the one that counts.

Heat — not washing — destroys bed bugs at all life stages. Run dryer-safe items on high for about 30 minutes after travel or handling secondhand clothing.

This makes a hot dryer a quick line of defense against hitchhikers before they ever reach your closet or bed. For anything that cannot go through a hot cycle, or if you already suspect a problem, a dedicated bed bug heat treatment approach may be needed. If you are unsure whether bugs are already present, a careful bed bug inspection should come first.

What Doesn't Prevent Bed Bugs

Because bed bugs feed on blood and travel by hitchhiking, several popular habits do little to keep them away. These are not reliable prevention:

Prevention comes from inspecting, heat-treating textiles, checking used items, and monitoring — not from housekeeping.

Frequently Asked Questions

How do you avoid bed bugs when traveling?
When you check into a room, pull back the sheets and inspect the mattress seams, headboard, and box spring for live bugs, shed skins, or small dark spots before you settle in. Keep your luggage off the bed and floor — use the luggage rack away from the wall, or set your bag in the bathtub while you check. When you get home, run washable clothing through a hot dryer, since heat is what kills any hitchhikers.
Does a hot dryer actually kill bed bugs?
Yes. Bed bugs and their eggs are killed by sustained heat, so running clothing and other dryer-safe textiles on a hot cycle for about 30 minutes destroys any bugs hiding in the fabric. The heat, not the wash water, is what does the work, so the dryer step is the important one. Items that cannot go in the dryer need another approach.
Can you prevent bed bugs completely?
There is no way to guarantee you will never encounter bed bugs, because they spread by hitchhiking on people and belongings and can turn up anywhere people gather. What you can do is sharply lower your risk: inspect where you sleep away from home, protect and treat your luggage and clothing, check used items before bringing them in, and monitor your own bed so any problem is caught early.
Does renters insurance cover bed bugs?
Usually not. Standard renters insurance policies typically exclude insect infestations, treating bed bugs as a pest-control or maintenance issue rather than a covered sudden loss. Coverage varies by insurer and location, so the only reliable answer is to read your own policy and ask your provider directly rather than assuming you are protected.
Do secondhand furniture and clothing bring bed bugs?
They can. Used furniture, mattresses, and clothing are a common way bed bugs travel into a home, so inspect any secondhand item carefully before bringing it inside. Check seams, folds, joints, and cracks for live bugs, eggs, shed skins, or dark spots, and run used clothing through a hot dryer to kill anything hiding in the fabric.
Do mattress encasements help prevent bed bugs?
They help. A bed bug encasement seals the mattress and box spring so bugs cannot get into or out of the many seams and folds where they like to hide, which makes an early problem easier to spot and control. An encasement is one layer of prevention, not a standalone cure, and works best alongside inspection and regular monitoring.
