Both chemical (conventional) and heat treatments eliminate bed bug infestations. Each works differently, each requires different prep, and each has trade-offs. This guide describes both methods neutrally so a Michigan homeowner can understand which fits their situation, and explains why BTR's $399-starting chemical treatment with a half-price follow-up is the most common Metro Detroit choice.
How Chemical (Conventional) Treatment Works
A chemical treatment applies a professional residual insecticide to every harborage location bed bugs use: baseboards, the seams and tufts of one mattress or couch, every dresser drawer (emptied), side-table drawers, headboard joints, and the carpet-to-baseboard line. The chemical kills bed bugs on contact and continues to kill bugs that move through treated surfaces for several weeks. Because bed bug eggs resist most chemicals, a second treatment 7 to 14 days later catches the newly hatched generation before it reproduces. BTR's second treatment is priced at half the first.
How Heat Treatment Works
A heat treatment uses industrial-grade heaters to raise the temperature of the entire treatment area to 120 to 135 degrees Fahrenheit and hold it there for several hours. Sustained heat at that range kills every life stage of bed bugs, including eggs, in a single session. Heat penetrates wall voids, mattresses, and furniture without applying chemicals. The home must be fully cleared of heat-sensitive items beforehand — candles, electronics rated below 130°F, certain pets, plants, vinyl records, some art — and pets and people remain out for the full session, typically 6 to 10 hours.
Side-by-Side Comparison
| Trait | Chemical Treatment | Heat Treatment |
|---|---|---|
| Process | Residual insecticide applied to harborages | Whole-home heat raised to 120–135°F for hours |
| Visits | 2 (initial + half-price follow-up at 7–14 days) | Often 1 session; sometimes a follow-up inspection |
| Kills eggs | Follow-up catches hatchlings; eggs themselves resistant to many chemicals | Yes, in the same session |
| Time out of home | 4–6 hours for chemical to dry | 6–10 hours during the heat session |
| Prep work required | Empty drawers, wash linens hot, pull beds from walls | Same drawer / linen prep + remove heat-sensitive items (candles, vinyl, certain electronics, plants, pets) |
| Belongings at risk | Minimal — surfaces wiped or items washed after | Heat-sensitive items must be removed (some art, electronics, candles, plants) |
| Chemical residual | Yes — continues working for several weeks | No — once the heat ends, the protection ends |
| Re-infestation risk | Lower in the weeks after — residual catches new bugs | Same as before treatment after heat ends — only what is present during the heat is killed |
| BTR price | $399 starting (under 4,000 sq ft + 1 bed/couch) + $99/extra bed + half-price 2nd | Not currently offered by BTR — available from specialty heat-treatment providers in Metro Detroit |
What BTR Uses and Why
BTR uses chemical (conventional) treatment. The reasoning:
- The residual catches re-infestation. Bed bugs are brought in — in luggage, in second-hand furniture, through shared walls. Chemical residual continues protecting for several weeks after application, which catches early-stage re-infestation that heat treatment alone misses.
- The half-price second treatment catches the egg-hatch cycle. The structural cost saving is built into the price, which makes the math favorable: $399 + ~$199.50 = ~$598.50 for a one-bed-or-couch home under 4,000 sq ft.
- No heat-sensitive belongings to remove. Homes with art, vinyl, certain electronics, candles, or temperature-sensitive items avoid the heat-prep cost.
- Lower upfront cost. Heat treatment from specialty providers typically runs $1,500–$4,000 for a typical Michigan home; BTR's chemical protocol starts at $399 base.
Heat treatment is the right call in some narrow situations — chemical-sensitive households, very heavy infestations where every life stage needs single-session kill, or multi-unit buildings with extensive cross-unit movement. For those situations, BTR refers to a specialty heat-treatment provider rather than offering an inferior version of a service we do not specialize in.
Prep Work Either Way
Both methods require homeowner prep:
- Empty every dresser drawer and side-table drawer. Bed bugs harbor in drawer seams and folded clothing.
- Wash all bedding, throw blankets, pillows, and clothing from the affected room in hot water and dry on high heat for 30+ minutes. High heat kills every life stage.
- Pull every bed 6 inches from the wall. The technician needs access to all sides.
- Vacuum the floor, baseboards, and any upholstered furniture before treatment. Empty the vacuum into a sealed bag immediately after, into outdoor trash.
- Remove pets, plants, and heat-sensitive items (the last specifically for heat treatment).
- Plan the 4–6 hour vacate (chemical) or 6–10 hour vacate (heat).
Cost & Decision Summary
For most Metro Detroit homes, BTR's chemical treatment is the practical choice: the price-and-protocol combination delivers a high success rate at $399 plus a half-price follow-up. Heat treatment is a specialty option for narrow situations where chemical residual is not acceptable or where heavy infestations make single-session whole-home heat the better fit.

Frequently Asked Questions
Which works better for bed bugs — heat or chemical?
Both work when applied correctly. Heat kills every life stage in one session but leaves no residual protection afterward. Chemical kills on contact plus continues to kill bugs that move through treated surfaces for several weeks, and a half-price second treatment catches the egg-hatch cycle. For most Michigan homes, the chemical-plus-follow-up protocol is more cost-effective; heat is a specialty fit for narrow situations.
Does heat treatment work in one visit?
Heat treatment usually requires one session of sustained 120–135°F for several hours. A follow-up inspection 1–2 weeks later is common to confirm. Because heat leaves no residual, any bed bugs introduced after the session can re-establish unless prevention (encasements, inspection on travel return, etc.) is in place.
How much does bed bug heat treatment cost in Michigan?
Specialty heat-treatment providers in Metro Detroit typically charge $1,500 to $4,000 per session for a typical home, depending on square footage and severity. BTR does not offer heat treatment — the conventional chemical protocol at $399 starting plus half-price second treatment is dramatically lower cost and works for most homes.
Is chemical treatment safe for pets and children?
Yes, with the prep done. BTR uses professional products applied as directed; everyone (including pets) vacates the home for 4–6 hours during application and drying. After the chemical has dried, the home is safe to re-enter. Bed bug chemicals are applied to harborages (baseboards, drawer interiors) not living surfaces.
Do I have to throw out my mattress?
Usually no. The base BTR bed bug treatment includes one bed or one couch. Encasement covers (bed-bug-proof mattress and box spring covers) put on after treatment trap any surviving bugs in the mattress so they die over time and prevent new ones from harboring. A heavily infested mattress is sometimes worth replacing; most are treatable.
What about a chemical-sensitive household?
Households with chemical sensitivities, infants, or specific medical conditions sometimes prefer heat treatment. In those cases BTR refers to a specialty heat-treatment provider rather than applying a chemical product. The choice is the homeowner's, and the trade-off is the higher heat-treatment cost vs the residual protection chemical provides.
Can heat and chemical be combined?
Yes, in severe infestations a heat treatment followed by chemical residual application is sometimes used — the heat takes down the active population in one session and the chemical residual protects against re-infestation. The combined cost is high (heat-treatment base + chemical base), but it is the most aggressive option available for heavy multi-room infestations.
Bed Bug Issue?
