You’ve scheduled your bed bug treatment — the hardest decision is behind you. But what you do before the treatment matters more than most people realize. Proper preparation is one of the biggest factors in whether a treatment fully eliminates the infestation or leaves survivors behind.
This guide walks you through exactly how to prepare, whether you’re getting a heat treatment, a chemical treatment, or a combination of both. Follow these steps and you’ll give your treatment the best possible chance of working the first time.
Why Preparation Matters So Much
Bed bugs are experts at hiding. They tuck into mattress seams, baseboards, furniture joints, and wall voids — the exact places that are hard to reach. Treatment works by reaching those hiding spots, and preparation is what clears the path.
When a home isn’t properly prepped, a few things happen: clutter blocks heat or product from reaching bed bugs, hiding spots get missed, and the infestation can survive in pockets the treatment couldn’t access. A well-prepped home, on the other hand, lets the treatment do its job thoroughly.
If you’re still not totally sure you’re dealing with bed bugs, our guide on how to tell if you have bed bugs can help you confirm the signs before treatment day.
General Prep: What to Do Before Any Treatment
These steps apply whether you’re getting heat, chemical, or combined treatment.
Wash and bag your laundry. Wash all clothing, bedding, linens, and fabric items in hot water, then dry on the highest heat setting the fabric allows. Heat kills bed bugs at every life stage. Once items are treated, seal them in clean plastic bags to keep them protected until the treatment is complete.
Reduce clutter. Clutter is a bed bug’s best friend — it creates endless hiding spots and blocks treatment from reaching them. Clear out unnecessary items, but don’t move them from room to room, which can spread the infestation. Bag clutter and keep it contained.
Don’t move furniture between rooms. It’s tempting to start rearranging, but moving infested items to “clean” rooms is one of the fastest ways to spread bed bugs through your home. Leave everything in place unless your technician instructs otherwise.
Make hiding spots accessible. Pull beds slightly away from walls, clear space around baseboards, and make sure your technician can reach mattresses, furniture, and corners. The easier the access, the more thorough the treatment.
Vacuum thoroughly. Vacuum floors, carpets, mattress seams, and baseboards. Immediately empty the vacuum into a sealed bag and dispose of it outside in an outdoor trash bin.
How to Prepare for a Heat Treatment
Heat treatment raises your home’s temperature to between 120°F and 140°F, which means some extra prep is needed to protect heat-sensitive items.
Remove heat-sensitive items, including:
- Candles, crayons, and anything that melts
- Aerosol cans and pressurized containers
- Medications and vitamins
- Fresh food and produce
- Houseplants and pets (pets must always be removed)
- Certain electronics, musical instruments, and valuables your technician flags
Leave interior doors open so heat can circulate freely through the entire space.
Don’t worry about most furniture and belongings — heat treatment is designed to treat your home without you throwing everything out. Your technician will provide a specific checklist of what to remove during your inspection.
Your full prep checklist will be tailored to your home — every situation is a little different, which is why we start with a free inspection to walk you through the specifics.
How to Prepare for a Chemical Treatment
Chemical treatment targets bed bugs with professional-grade products applied to cracks, crevices, and hiding spots. Prep focuses on access and safety.
- Clear items away from baseboards, walls, and furniture edges where products will be applied
- Wash and seal bedding and clothing as described above
- Remove pets, including fish tanks (cover and turn off pumps if they can’t be removed)
- Plan to stay out of treated areas until your technician confirms it’s safe to return
- Avoid cleaning or mopping treated areas immediately after, which can remove the product before it works
What NOT to Do Before Treatment
Some well-intentioned actions actually make treatment harder. Avoid these:
Don’t use DIY sprays or foggers beforehand. Store-bought “bug bombs” scatter bed bugs deeper into hiding and can make a professional treatment less effective. If you’ve already tried DIY, just let your technician know — it helps them plan. Our article on when to call a professional exterminator explains why DIY so often backfires.
Don’t throw out your furniture (usually). People panic and toss mattresses and couches, but professional treatment can often save them. If an item truly needs to go, our furniture removal service handles infested items safely without spreading bugs. Ask your technician before discarding anything.
Don’t move out or sleep in another room. It sounds logical, but leaving the infested area can actually cause bed bugs to spread as they search for a host. Stay put until treatment day unless instructed otherwise.
Don’t skip the prep checklist. This is the big one. Incomplete prep is the most common reason a treatment underperforms.
What to Expect on Treatment Day
When our team arrives, we’ll do a final walkthrough, confirm prep is complete, and explain the process and timeline. For heat treatments, you and your pets will need to be out of the home during the treatment and can typically return the same day once the home has cooled and been cleared. For chemical treatments, we’ll let you know exactly when it’s safe to re-enter treated areas.
Throughout the process, our goal is simple: treat your home thoroughly, communicate clearly, and get you back to sleeping comfortably as fast as possible.
