Biting pests
Bed bug heat and non-chemical control
Bed bugs die when their bodies and harborages reach lethal temperatures for long enough. Whole-room heat is a professional method. DIY hair dryers do not heat a box spring core. Non-chemical control also includes encasements, interceptor cups, laundering, and clutter removal. Insecticides can help but resistance in Cimex lectularius is well documented.
When this method is the right tool
Use this playbook for confirmed bed bugs in sleeping areas, hotels, and transit. Do not heat a room with aerosols, pets, or aerosols in cans you forgot on a shelf. Professionals plan for sprinklers, electronics, and escape into adjacent apartments.
How to do it
- Confirm the insect. Bat bugs and carpet beetles confuse people. A specimen beats a bite guess.
- Reduce clutter. Bags of clothes are apartments. Bag, launder hot, or run a dryer on high for 30 minutes or more for infested fabric.
- Encase mattresses and box springs. Use bed-bug-rated zip encasements. Install interceptors under bed legs.
- Treat harborages. Professionals may use heat, steam (carefully), vacuuming, and labeled products. Adjacent units in apartments often need inspection the same week.
- Follow up. Eggs hatch. One treatment is rarely the end. Monitor for weeks.
Containment tools around a bed-bug job
Encasements and interceptors support inspection. Heat treatments still belong to people who will not set a bedroom on fire.

Hardware
Zippered mattress and box-spring encasement
Encasements trap bugs already in the mattress and make inspection possible. Buy a true bed-bug-rated zipper, not a thin mattress cover. This is one step in a program, not a fogger substitute.
Hardware
Bed-bug interceptor cups
Under bed and sofa legs they show whether the infestation is still moving. Combine with laundry heat and a real inspection. Interceptors are not a treatment for a multi-family stack.
Labeled product
Hot Shot indoor insect fogger
Total-release cans for enclosed rooms. Follow the EPA label: leave the structure, cover aquariums, keep flames and pilots as the can requires, and stay out for the stated time. Poison control in the US: 1-800-222-1222.
Mistakes that waste money
- Throwing out a mattress as the only step (bugs stay in baseboards).
- Using outdoor foggers in a bedroom.
- Moving infested furniture to a guest room “temporarily.”
Safety
CDC notes bed bugs are not typical disease vectors in the US, but pesticides misused in bedrooms cause real poisonings. Never use agricultural products indoors. Heat treatments must respect fire and sprinkler limits.

Common questions
Will freezing my stuff work?
Deep cold can work if the entire item stays below lethal temperature long enough. A garage in autumn is not a freezer. When in doubt, a hot dryer for fabrics is more reliable.
