Preparing your home properly before bed bug treatment is one of the biggest factors in whether the treatment works. Poor preparation is a leading cause of treatment failure, and skipping steps can actually spread the infestation to other rooms. The specifics depend on whether you’re getting a chemical (conventional) treatment or a heat treatment, but both require real effort on your part beforehand.
The Most Important Rule: Don’t Move Things Between Rooms
Your first instinct might be to grab clothes, bags, or furniture from the infested room and relocate them somewhere “safe.” Don’t. Moving items out of infested rooms before treatment is one of the fastest ways to spread bed bugs to parts of your home that were previously clean. Bed bugs hide in seams, folds, and tiny crevices you won’t see, and carrying an infested item into another room seeds a brand-new problem. Everything stays in place until your pest control professional says otherwise.
Preparing for Chemical Treatment
Conventional treatment uses pesticides applied to cracks, crevices, baseboards, bed frames, and other hiding spots. To give the technician full access and maximize the treatment’s reach, you need to do several things ahead of time.
Pull beds, couches, and other furniture away from walls so the technician can treat behind and beneath them. Strip all bedding, pillowcases, and mattress covers and bag them for laundering (more on that below). Empty nightstands and dressers in the bedroom, placing contents into sealed plastic bags. Clear out anything stored under the bed.
Remove all clutter from floors, closets, and along baseboards. Bed bugs thrive in cluttered spaces because clutter creates hiding spots that pesticides can’t reach. The fewer places bugs can shelter, the more effective the treatment will be. Bag up loose items like books, shoes, and toys in sealed plastic bags so the technician can treat the surfaces underneath.
All people and pets need to leave the home during application and for whatever re-entry period your technician specifies. Fish tanks deserve special attention: cover them, turn off air pumps (which can pull airborne chemicals into the water), and ask your technician whether the tank needs to be removed entirely.
Preparing for Heat Treatment
Heat treatment works by raising the temperature of your entire home (or targeted rooms) to at least 122°F and holding it there over the course of a four- to five-hour session. Bed bugs die within 20 minutes at 118°F, but their eggs are tougher, requiring 90 minutes at 118°F to reach full mortality. The advantage of heat treatment is that it penetrates into furniture, walls, and belongings without chemicals. The preparation is different, too.
Unlike chemical treatment, you typically don’t need to declutter extensively before heat treatment, since the heat penetrates through piles of belongings. However, the technician will need to move items around frequently during the process to increase airflow, so don’t expect everything to be in its original place afterward.
What you do need to remove from the home:
- Pets and houseplants. Neither can survive the temperatures involved.
- Candles, lipstick, crayons, and anything wax-based. These will melt.
- Aerosol cans and cigarette lighters. Pressurized containers and combustibles are a fire and explosion risk at high heat.
- Medications. Heat can degrade or destroy active ingredients.
- Non-refrigerated produce. Fruit, bread, and similar items will cook.
- Stringed instruments, family heirlooms, and photographs. Wood can warp, adhesives can soften, and photos can be permanently damaged.
Electronics should be disconnected from outlets. Televisions and monitors are often recommended to be removed or wrapped in blankets to protect them from direct heat exposure. Ask your technician for specifics, as recommendations vary by company.
How to Handle Laundry
Every piece of fabric that could harbor bed bugs needs to go through the dryer. A loosely filled household dryer set on high kills all bed bug life stages, including eggs, in 30 minutes. This applies to clothes, bedding, pillowcases, curtains, stuffed animals, fabric bags, and anything else that’s dryer-safe.
The key word is “loosely filled.” An overstuffed dryer won’t reach lethal temperatures throughout the load. Run smaller loads and give items room to tumble freely. For items that can’t go through the dryer (delicate fabrics, certain shoes), sealing them in plastic bags and discussing options with your technician is a safer bet than guessing.
Wash items first if they’re dirty, but know that the dryer is what actually kills the bugs. Washing alone in hot water can work, but it requires sustained temperatures of at least 113°F for 90 minutes or 118°F for 20 minutes, which most household washing machines don’t reliably maintain. The dryer on high is the reliable kill method.
Once items come out of the dryer, seal them immediately in clean plastic bags. Don’t put clean clothes back into infested drawers or closets until after treatment is complete.
Vacuuming Before Treatment
Vacuuming won’t solve a bed bug problem on its own, but it reduces the number of live bugs and eggs before treatment, giving the chemicals or heat less work to do. Focus on mattress seams, box spring crevices, bed frame joints, baseboards, carpet edges, and upholstered furniture seams. Use a stiff brush to scrub along mattress stitching and seams before vacuuming, which helps dislodge eggs that are glued to fabric.
If your vacuum uses disposable bags, remove the bag immediately after vacuuming, seal it inside a plastic garbage bag, and throw it in an outdoor trash can. If you have a bagless vacuum, you risk contaminating it with bed bugs that can crawl back out. In that case, empty the canister into a plastic bag, seal it tightly, and wipe down the canister interior with a damp cloth.
Installing Mattress and Box Spring Encasements
Encasements are zippered covers that seal your mattress and box spring completely, trapping any bed bugs inside and preventing new ones from colonizing the seams. Your technician may recommend installing them before or after treatment, so ask about timing.
Before putting an encasement on, scrub the mattress seams with a stiff brush and vacuum thoroughly. Wipe up any visible bugs with a damp paper towel, crush them inside it, and seal the towel in a plastic bag before disposing of it. Inspect the bed frame and box spring for sharp edges, bolts, or rough spots that could puncture the encasement. Adhesive felt pads can cover these areas.
Once installed, the encasement stays on permanently. You can put fitted sheets and regular bedding over it and launder those normally, but the encasement itself should not be removed. Check it every few months for rips or worn spots where bugs could escape. Both the mattress and box spring need their own encasements to be effective.
What to Do After Treatment
Don’t clean treated surfaces right away. With chemical treatment, the residual pesticide on baseboards, bed frames, and floor edges continues killing bed bugs for days or weeks after application. Mopping or wiping those areas too soon removes the product and reduces effectiveness. Ask your technician exactly which surfaces are safe to clean and which should be left alone.
Continue sleeping in your bedroom after treatment, even if that feels counterintuitive. If you move to the couch or a spare room, bed bugs may follow you there, spreading the infestation. Your presence in the treated room actually helps, because bugs that come out to feed will cross treated surfaces.
Most infestations require more than one treatment. Expect a follow-up visit, typically two to three weeks later, to catch any bugs that hatched from eggs after the initial treatment. Keep your belongings organized, maintain encasements on your mattress and box spring, and continue checking for signs of activity: small dark spots on sheets, shed skins, or new bites. The weeks between treatments are when your vigilance matters most.
