Bed bugs are among the most difficult pests to eliminate — and the area where homeowner preparation, professional technique, and realistic expectations matter most. A poorly executed bed bug treatment leaves surviving eggs that hatch into a new generation within weeks. A well-executed treatment, whether heat or chemical, requires thorough preparation by the homeowner and typically multiple visits by the professional. Understanding what you’re committing to before the treatment begins is essential.

“Bed bugs are the pest where homeowner preparation makes or breaks the outcome. The treatment itself — whether heat or chemical — can be excellent. But if the homeowner doesn’t prepare properly, the professional is treating a room full of clutter that’s harbouring untreated bugs. Preparation is not optional. Ask the company exactly what you need to do before they arrive, in writing, and make sure you understand it before you book.”

Questions About the Inspection

Will you perform a thorough inspection before proposing treatment?

A bed bug inspection should cover:

  • Mattress seams, tags, and tufts
  • Box spring fabric and frame (a common harborage site)
  • Bed frame joints and slat ends
  • Nightstand drawers, backs, and undersides
  • Picture frames and wall hangings near the bed
  • Electrical outlets and switch plates near the bed
  • Upholstered furniture (seams, cushion creases, undersides)

Ask whether the inspection includes all of these areas and whether the inspector uses any detection tools (CO2 monitors, flashlights) to identify hiding sites.

Can you confirm this is bed bugs and not another pest?

Bed bugs are often confused with other insects — carpet beetles, bat bugs, or even fleas. The treatment for each is different. Ask the company to confirm with certainty that what you have is bed bugs — ideally by showing you a live or dead specimen — before proposing any treatment.

Questions About Treatment Method

What treatment method are you proposing — heat, chemical, or a combination?

Heat treatment:
Raises the entire room or unit temperature to 50°C+ and maintains it long enough to kill all life stages including eggs. A single treatment, when properly executed, can achieve very high kill rates. No chemical residue. Requires thorough preparation (removing heat-sensitive items). Not effective in spaces with significant thermal “cold spots” (electronics, thick wood furniture) unless carefully managed.

Chemical treatment:
Multiple pesticide applications (typically 2–3 visits at 2-week intervals). The delay between treatments is necessary because chemical treatments don’t reliably kill eggs — the second and third visits address newly hatched nymphs. More preparation flexibility than heat, but requires living with a managed infestation for 4–6 weeks.

Combination:
Some companies offer heat + chemical as a belt-and-suspenders approach. Tends to be the most reliable for severe infestations.

Ask which method is being proposed, why it’s appropriate for your situation (severity of infestation, unit type, presence of heat-sensitive items), and what the evidence of effectiveness is.

What a good answer looks like: A specific method recommendation with a rationale tied to your specific infestation, not a generic package.

How many visits are required, and at what intervals?

For chemical treatment: typically 2–3 visits at 2-week intervals. Ask specifically:

  • What happens at each visit?
  • What products are applied at each visit?
  • How will success be confirmed between visits?

For heat treatment: typically one treatment, sometimes followed by a chemical spot treatment.

Questions About Preparation

Exactly what preparation is required before treatment?

Bed bug treatment preparation can be extensive. Ask for written preparation instructions before booking. Typical requirements include:

For heat treatment:
– Removing all heat-sensitive items (aerosols, candles, wine, chocolate, vinyl records, some medications)
– Removing pets, plants, and fish tanks
– Moving furniture away from walls to allow air circulation
– NOT putting items in plastic bags (bags trap cold air)
– Leaving all clothing and linens in place for treatment

For chemical treatment:
– Washing all bedding, clothing, and linens in hot water and drying on high heat (kills bugs and eggs)
– Vacuuming mattress, box spring, and upholstered furniture thoroughly
– Placing vacuumed debris in sealed bags and disposing outside immediately
– Clearing clutter from treated areas
– Moving furniture away from walls

Ask the company to provide their preparation checklist in writing.

What a good answer looks like: A written preparation guide provided at booking, not on the day of treatment.

What should I do with clothing and personal items?

Ask specifically where clothing, shoes, and personal items should go during and after treatment, and whether they need to be treated themselves.

Questions About Expectations

What is a realistic expectation for complete elimination?

Set realistic expectations before treatment begins:

  • Chemical treatment: 4–8 weeks to confirmed elimination, with multiple visits
  • Heat treatment: 1 treatment for well-prepared spaces, with possible follow-up spot treatment

Ask the company to describe what “success” looks like and when you can reasonably expect to confirm the infestation is eliminated.

What is the guarantee?

Ask specifically: if live bed bugs are found after the final treatment visit within the guarantee period, is re-treatment included at no charge?

What a good answer looks like: A written guarantee with a specific duration (typically 30–90 days after the final treatment), covering re-treatment if live bugs are confirmed.

What should I do if I see bed bugs between treatment visits?

For chemical treatment programs, seeing some bugs between visits is expected and doesn’t necessarily mean the treatment isn’t working. Ask what you should do if you see activity between visits — contact the company, monitor and document, or apply any supplemental measures yourself.
