How to Wash Clothes to Kill Bed Bugs

Finding bed bugs in your home can make even “normal” chores feel high-stakes, especially laundry. The good news is that washing and drying can kill bed bugs on clothing, bedding, and other washable fabrics when you use the right heat and handling steps. This guide explains the temperature targets that matter, how long to run each cycle, and how to move items without spreading hitchhikers. You’ll also learn where laundry helps most – and where you’ll need additional control methods.

Quick Answer: How to Wash Clothes to Kill Bed Bugs

To kill bed bugs in laundry, heat is the deciding factor, not special soap. The most reliable approach is a hot dryer cycle, with careful bagging to prevent spread.

Use this quick checklist:

• Bag first: Seal items in plastic bags before moving them.
• Dryer first when possible: Run high heat for 30-60 minutes (longer for bulky loads).
• Wash hot (fabric-safe): Use the hottest water the fabric allows, then dry again on high.
• Don’t overpack: Heat must reach seams, waistbands, cuffs, and pockets.
• Re-bag clean items: Keep them sealed until the room is treated.

Temperature goal: Bed bugs and eggs die when exposed to sustained high heat. Public health guidance commonly emphasizes hot laundering and hot drying as dependable tools, especially when paired with other controls, such as encasements and targeted treatment. For broader home steps, see this complete guide to getting rid of bed bugs.

Why Heat Works on Bed Bugs (and Why Detergent Usually Doesn’t)

If bed bugs were easy to drown in soapy water, they wouldn’t be such persistent pests. What makes them tough in a bedroom also makes them hard to eliminate with “laundry hacks.” Bed bugs (Cimex lectularius) hide in folds and seams, cling to fabric, and can tolerate short exposures to mild heat or cool water.

Heat works because it damages proteins and disrupts the insect’s ability to regulate moisture. Eggs are the real hurdle. Adult bed bugs and nymphs can die relatively quickly at high temperatures, but eggs can be more resistant, so time + heat is the winning combination.

Here’s what to keep straight:

• Detergent helps clean, not kill. Regular detergent is fine. It removes stains and body oils, but it is not a bed bug insecticide.
• Hot water helps, but the dryer is often the “finisher.” Washing can reduce and sometimes kill bugs, yet a hot dryer cycle is typically more reliable because it surrounds the fabric with sustained heat.
• Your washer temperature may not be what you think. Many home washers do not maintain a consistent high temperature through the full cycle, especially on “eco” settings.

What temperature actually kills them? Many pest management resources and public health documents point to lethal effects when bed bugs are held at high temperatures long enough, with stronger reliability as temperatures rise. For practical home guidance, several pest control references emphasize that high-heat laundering and drying can eliminate bed bugs on fabrics when done correctly. A bed bug advisory from the South Carolina Department of Public Health also highlights hot laundering and hot drying as part of home management.

Action takeaway: If you do only one thing, prioritize high-heat drying and careful transport. Then treat the room so clean items stay clean.

Step-by-Step Laundry Protocol That Actually Kills Bed Bugs

Most laundry failures happen before the washer starts. Bed bugs spread when people carry loose piles down the hall, set bags on the couch, or sort clothes on the bed. Think of bed bugs like burrs that don’t want to let go. Your job is to keep them contained until heat finishes the job.

1) Bag, seal, and stage your laundry

Before you pick anything up:

1. Place a clean plastic bag (or dissolvable laundry bag) inside the infested room.
2. Load items directly into the bag – don’t hug piles to your chest.
3. Seal the bag tightly before leaving the room.

If you can, bring a second bag to create a “double-bag” system:

• Dirty bag: holds potentially infested items.
• Clean bag: used only after items are heat-treated.

2) Decide: dryer-first or wash-first?

In many real homes, dryer-first is the most dependable for killing bed bugs on clothing because it delivers sustained heat without relying on your washer’s thermostat.

Use this simple decision chart:

Visual: Choose your order

• Dryer-first if:

  • Items are dry already (jackets, clean clothes, linens off the shelf).
  • Fabrics tolerate heat.
  • You want the most reliable kill step up front.

• Wash-first if:

  • Items are visibly soiled.
  • Fabric can handle hot water.
  • You’ll still dry on high immediately afterward.

3) Run the dryer hot enough, long enough

Set the dryer to the highest heat the fabric allows. Run time depends on load size and thickness.

• Light clothing: 30-40 minutes on high heat is commonly recommended in practice.
• Bulky items (towels, hoodies, comforters): 60+ minutes may be needed so heat reaches inner layers.

Avoid overfilling. A tightly packed drum insulates the center of the load, which can leave cooler pockets where bugs or eggs survive.

4) Wash hot (only if fabric-safe), then dry again

After drying (or before, if you chose wash-first), wash using:

• The hottest water safe for the fabric label
• Regular detergent
• A full wash cycle (not a quick rinse)

Then transfer immediately to the dryer. Don’t leave wet laundry sitting in a basket where a stray bug can climb back in.

5) Store clean items so they can’t be re-infested

This step is where people accidentally reset the clock. If the room still has bed bugs, clean clothes left in open baskets can get re-infested overnight.

• Place clean, dried items into a fresh sealed bag or lidded bin.
• Keep them sealed until the sleeping area is treated and monitored.

Visual: “Do this, not that” handling list

• Do: seal bags before leaving the room
• Do: empty bags directly into the washer or dryer
• Do: wipe down baskets or use a dedicated “laundry-only” tote
• Don’t: sort on the bed or carpet
• Don’t: carry loose armfuls through the home
• Don’t: store clean items in the infested room uncovered

What Laundry Can’t Do (and How to Pair It With Room Treatment)

Laundry is a strong tool, but it’s not a whole-home solution. Bed bugs rarely live only in clothing. They prefer to stay close to a host, which means mattresses, bed frames, headboards, nightstands, baseboards, and even screw holes. If you wash everything you own but leave the bed and room untreated, the population can rebound quickly.

Common situations where laundry falls short

Laundry alone won’t eliminate an infestation when:

• Bed bugs are in mattress seams, box springs, or bed frame joints
• They’re hiding behind baseboards, outlet plates, picture frames, or loose wallpaper
• The problem has spread to couches, recliners, or adjacent rooms
• You’re seeing new bites despite freshly laundered bedding

A smart next step is confirming the scope. Use this checklist of signs of bed bug infestation to decide whether you’re dealing with a few hitchhikers or an established colony.

Pair laundry with these proven controls

Entomologists and pest managers typically recommend combining fabric heat treatment with targeted room steps:

Visual: Laundry + room treatment combo plan

1. Vacuum carefully

   • Focus on mattress seams, bed frame joints, carpet edges, and cracks.
   • Empty the canister into a sealed bag immediately.

2. Use steam where chemicals can’t go

   • Steam can reach into seams and crevices where bed bugs hide.
   • For practical device guidance, see bed bug steamers for home use.

3. Encase mattress and box spring

   • Encasements trap any missed bugs inside and remove hiding places outside.
   • Keep encasements on for the recommended duration (often many months).

4. Use a labeled residual product when appropriate

   • If you choose sprays or dusts, use products labeled for bed bugs and follow the label exactly.
   • Compare options in our roundup of the best bed bug sprays and killers.

When to call a professional

Consider professional help if:

• You see bed bugs in multiple rooms
• You can’t reduce bites after 2-3 weeks of consistent effort
• You live in a multi-unit building (spread between units is common)
• Someone in the home has health vulnerabilities that make prolonged exposure risky

The EPA’s bed bug prevention and control guidance supports an integrated approach: inspection, non-chemical controls (like heat and encasements), and careful product use when needed.

Special Cases: Delicates, Dry Cleaning, and “No-Heat” Fabrics

Not everything belongs in a hot wash or high dryer. Delicate fabrics, structured garments, and items with elastic, glue, or specialized finishes can shrink, warp, or fall apart. The goal is still the same: expose bed bugs and eggs to lethal conditions without ruining your belongings.

Dry cleaning for delicate clothing

Dry cleaning can be a practical option for:

• Suits, wool, silk, lined dresses, and structured jackets
• Items labeled “dry clean only”
• Garments with complex seams and layers

Many dry cleaning processes use elevated temperatures during cleaning and pressing, and the solvents and agitation help remove pests from fabric folds. Some pest control and cleaning industry explanations note that dry cleaning can kill bed bugs on garments when the full process is completed, including pressing. For a general overview of how cleaners approach this, see the explanation from Hangers Cleaners on dry cleaning and bed bugs.

What to say at the counter (simple script):

• “These items may have been exposed to bed bugs. Can you process them fully and return them sealed?”

Many cleaners already have protocols for bagging and handling. If they don’t, choose another cleaner.

Items you can’t wash or dry

For shoes, bags, books, and heat-sensitive items, consider:

Visual: Alternatives to hot laundry

• Sealed storage + time

  • Place items in airtight bins or bags.
  • Time frames vary with temperature and conditions, so this is slower and less predictable than heat.

• Targeted heat treatment devices

  • Some households use portable heat chambers designed for belongings. Follow manufacturer instructions closely.

• Careful inspection + vacuuming

  • Focus on seams, zippers, and folds where bed bugs hide.

If you’re unsure whether an item can tolerate heat, check the care label and test a small area first. When in doubt, dryer heat can be more damaging than hot water.

Common laundry myths to ignore

• Myth: “Special detergents kill bed bugs.” Heat is what does the killing.
• Myth: “Cold wash is fine if I dry later.” If you skip heat or under-dry, survivors can remain.
• Myth: “A quick cycle is enough.” Short cycles and overpacked loads are a common reason infestations linger.

If you want a room-by-room plan that goes beyond laundry, this complete guide to getting rid of bed bugs lays out a practical sequence.

Laundry Safety Checklist: Prevent Spreading Bed Bugs During Washing

Laundry can either shrink the problem fast or spread it to new rooms. The difference often comes down to small habits: where you set the bag, how you carry it, and what you do with the container afterward.

Here’s a simple routine that pest pros use because it reduces “oops” moments.

The safest way to move laundry

Visual: Containment checklist

1. Prepare your path

   • Clear a route to the laundry area.
   • Keep bags off beds, couches, and carpets.

2. Use sealed bags

   • Tie off tightly or use zipper bags.
   • If a bag tears, place it inside a second bag immediately.

3. Empty directly into the machine

   • Don’t dump onto the floor to “sort.”
   • If you must sort, do it inside a bathtub or on a hard surface you can wipe.

4. Treat the container

   • If you used a hamper, wipe it with hot soapy water or a suitable cleaner.
   • Consider dedicating one tote for “treatment loads” until the issue is resolved.

5. Keep clean items isolated

   • Seal clean clothes in bags or bins until your sleeping area is treated and monitored.

A practical “laundry zone” setup

If you’re actively dealing with bed bugs, set up two zones:

• Dirty zone: bags waiting to be treated
• Clean zone: sealed bags/bins that never touch the dirty zone

This sounds picky, but it prevents the most frustrating scenario: doing everything right in the dryer, then re-contaminating items in the same basket.

When you should re-wash

Re-wash (or at least re-dry) items if:

• Clean laundry sat uncovered in an infested room
• You found a live bug in a clean pile
• You moved items through a heavily infested area unbagged

If bites continue despite careful laundry, confirm you’re not missing hiding sites. This guide to signs of bed bug infestation helps you pinpoint where they’re nesting.

Conclusion: Use Laundry as Your Fastest “Win,” Not Your Only Tool

Washing and drying can kill bed bugs on clothing and bedding, but the method works best when you focus on containment, high heat, and enough time. Bag items before moving them, avoid overpacked loads, and rely on a high-heat dryer cycle to finish the job. Then store clean items sealed so they don’t get re-infested while you treat the room.
