How to Prepare for Bed Bug Heat Treatment
Preparing properly for bed bug heat treatment helps your technician distribute and monitor heat effectively while protecting belongings that may be sensitive to elevated temperatures.
But preparation doesn't mean emptying your entire house, throwing belongings away or randomly bagging everything you own.
The objective is simple: give the treatment team good access, allow heated air to circulate and identify anything that should not be exposed to treatment temperatures.
Always follow the preparation instructions supplied specifically for your treatment. If MothKill has given you instructions that differ from general advice online, follow the instructions for your booked treatment.
🔥 Bed Bug Heat Treatment Preparation: Quick Checklist
- Clear excessive clutter from floors and around beds.
- Do not move potentially infested belongings into untreated rooms.
- Remove people and pets from the treatment area.
- Remove plants where instructed.
- Remove aerosols, pressurised containers and flammable materials.
- Remove medicines and heat-sensitive personal products where advised.
- Tell MothKill about delicate plastics, blinds, rails and laminated furniture.
- Keep access to beds, furniture and room edges clear.
- Tell us about electronics or specialist equipment you are concerned about.
- Do not throw away mattresses or furniture unless there is another reason to do so.
Why Preparation Matters Before Bed Bug Heat Treatment
Professional heat treatment works by creating sufficient thermal exposure throughout the treatment area.
Bed bug eggs, nymphs and adults can be killed by heat when sufficient temperatures reach them for sufficient exposure.
But different parts of a room do not necessarily heat at the same speed.
Furniture, belongings, airflow restrictions and the layout of the property can all affect how heat moves.
That's why professional treatment involves more than simply raising the room's air temperature.
MothKill uses professional heating equipment, industrial fans and multiple temperature sensors so that treatment isn't judged from a single air-temperature reading.
How MothKill Bed Bug Heat Treatment Works
For our professional heat treatments, the main indirect diesel heating equipment remains outside the property.
- Combustion gases remain outdoors.
- Clean heated air is ducted into the treatment area.
- Industrial fans help circulate the heated air.
- Multiple temperature sensors monitor different locations.
- Slower-heating areas can be identified during treatment.
People and pets do not remain in the actively heated treatment area.

1. Don't Move the Infestation Around the House
Keep Potentially Infested Belongings Within the Treatment Plan
One of the biggest preparation mistakes is moving belongings from an affected bedroom into another room that isn't being treated.
Avoid unnecessarily carrying:
- bedding;
- clothing;
- bags;
- boxes;
- soft furnishings;
- bedside items; or
- other potentially exposed belongings
from an affected room into an untreated part of the property.
If something needs to be removed because it is heat-sensitive, follow the instructions given by MothKill so it can be handled in a way that reduces the chance of moving bed bugs with it.
2. Clear Excessive Clutter
Give Heated Air and the Technician Room to Work
You don't need to turn the property into an empty shell, but excessive clutter can obstruct airflow and make inspection and treatment more difficult.
Before treatment:
- clear obvious clutter from floors;
- remove rubbish;
- make areas beneath beds accessible;
- clear excessive piles around furniture;
- make room edges reasonably accessible; and
- ensure there is safe access through the property.
⚠️ Don't Declutter by Moving Everything Elsewhere
Clearing a bedroom by transferring all of its belongings into another untreated bedroom can potentially move the infestation with them. Ask before relocating questionable items.
3. Clothing, Bedding and Laundry
Don't assume every garment in the property needs to be removed and washed before professional heat treatment.
Excessive bagging can actually make preparation more complicated if potentially infested items are moved around unnecessarily.
If MothKill asks you to launder particular items:
- follow the garment's care label;
- contain potentially infested items before transporting them through the property;
- keep successfully treated or cleaned items separate from untreated belongings; and
- do not return clean items to an untreated infested area unnecessarily.
Delicate materials may require professional dry cleaning or another suitable approach rather than inappropriate high-temperature washing.
Do I Need to Bag Everything?
No — not automatically.
Bagging every possession without a plan can create sealed masses that are difficult to treat and can also result in potentially infested belongings being moved into untreated areas.
Bag items when there is a specific reason to contain them, remove them or keep treated items separated.
Follow the instructions for your particular treatment rather than generic advice telling you to bag the entire contents of the property.
4. Prepare the Bed and Sleeping Area
Keep the Main Harbourage Areas Accessible
Beds and the furniture immediately around them are important areas during bed bug treatment.
Before MothKill arrives:
- remove unnecessary items from beneath the bed;
- clear clutter around bedside furniture;
- make the bed frame accessible;
- tell us about divans, ottoman beds or unusual bed construction; and
- do not dispose of the mattress simply because bed bugs have been found.
Only dismantle furniture if MothKill has specifically asked you to do so.
5. Furniture: What Needs Special Attention?
Most homes contain a mixture of materials, and different materials react differently to elevated temperatures.
Tell us about anything you think may be unusually heat-sensitive.
Solid Furniture
Many conventional furniture items can remain during treatment, subject to inspection and the treatment plan.
Laminated Furniture
Laminates and adhesives can respond differently to heat. Tell us about laminated wardrobes, bedside units, desks and similar furniture.
MDF / Flat-Pack Furniture
MDF and laminated flat-pack furniture can be vulnerable to heat-related delamination or distortion, particularly where adhesives or thin surface finishes are involved.
Plastic Furniture & Fittings
Some plastics soften or distort at elevated temperatures and should be assessed before treatment.
6. Plastic Blinds, Rails and Fittings
⚠️ Please Tell Us About Plastic Blinds and Clothes Rails
Thin plastic components can be more vulnerable to heat than people expect.
This can include plastic blinds, blind components, lightweight clothes rails, hangers, curtain fittings and other plastic fixtures. Depending on the material and treatment plan, they may need to be removed or otherwise managed before heating.
If you're unsure what something is made from, point it out before treatment starts.
7. UPVC and Other Heat-Sensitive Plastics
UPVC and other plastics should not simply be assumed to tolerate treatment temperatures without risk.
Potential heat effects can include:
- softening;
- distortion;
- warping; and
- movement of fitted components.
MothKill will take the property and its materials into account when planning treatment, but customers should highlight anything unusual or particularly valuable before treatment begins.
8. Remove Aerosols and Pressurised Containers
Pressurised containers should not be left in the heated treatment area.
Examples include:
- deodorant aerosols;
- hairspray;
- air freshener aerosols;
- spray paint;
- pressurised cleaning products; and
- other pressurised cans.
These should be identified and removed according to the preparation instructions.
9. Remove Flammable and Volatile Materials
Tell MothKill about and remove items such as:
- petrol or fuel containers;
- solvents;
- some cleaning chemicals;
- lighter fuel;
- other flammable liquids; and
- anything specifically marked as requiring protection from heat.
If you're uncertain, ask rather than guessing.
10. Candles, Wax and Meltable Items
Remove items that may soften or melt when exposed to elevated temperatures.
These can include:
- candles;
- wax ornaments;
- wax-based products;
- some cosmetics;
- chocolate; and
- other easily meltable materials.
11. Medicines and Medical Items
Medicines and specialist medical products can have manufacturer-specified storage temperatures.
Take required medication with you and remove medicines from the heated treatment area unless MothKill has specifically confirmed otherwise.
This includes prescription medicines and temperature-sensitive medical products.
12. Electronics
Electronics are one of the most common things customers worry about.
There is no sensible universal rule saying that every television, computer or electronic device must either stay or go.
The correct decision depends on the equipment and its specified storage limits.
Before treatment:
- tell us about expensive or specialist electronic equipment;
- switch off equipment where instructed;
- do not cover electronics in piles of clothes or blankets;
- remove specialist equipment if advised; and
- take essential work equipment with you if you will need it during the treatment.
13. Batteries and Battery-Powered Equipment
Tell MothKill about devices containing batteries, particularly specialist or high-value equipment.
Battery storage and operating limits vary by manufacturer and battery type.
Where there is any doubt, the manufacturer's temperature specifications should be considered rather than assuming the item is suitable for treatment.
14. Plants
Houseplants can be damaged by elevated treatment temperatures.
Where instructed, remove them from the heated treatment area before treatment starts.
Be careful when moving pots, baskets or containers from an infested room, as bed bugs can shelter in objects rather than living on the plant itself.
15. Pets
Pets must not remain in the actively heated treatment area.
This includes:
- dogs;
- cats;
- birds;
- rabbits;
- hamsters and other small mammals;
- reptiles; and
- other pets.
Fish tanks and specialist animal enclosures need particular consideration. Tell MothKill about them before treatment day so suitable arrangements can be discussed.
16. People Must Leave the Heated Treatment Area
Customers, children, visitors and other occupants cannot remain in rooms while they are being actively heated.
Plan ahead for:
- where you will go;
- medicines you need;
- work equipment;
- keys;
- children's essentials; and
- anything else you will need during the treatment period.
MothKill will advise you when treated areas can be re-entered.
17. Valuable and Irreplaceable Items
Tell us about anything that is particularly valuable, fragile, antique, unusual or irreplaceable.
Examples include:
- antique furniture;
- valuable artwork;
- musical instruments;
- photographic collections;
- collectables;
- delicate plastics;
- specialist equipment; and
- items with unknown heat tolerance.
It is much easier to assess an item before treatment than deal with avoidable damage afterwards.

What NOT to Do Before Bed Bug Heat Treatment
❌ Don't Move Everything
Moving potentially infested belongings into untreated rooms can make control more difficult.
❌ Don't Throw the Bed Away
A mattress does not automatically need replacing because bed bugs have been found.
❌ Don't Spray Random Products
Don't apply unplanned insecticides, foggers or other products immediately before treatment without discussing them with your technician.
❌ Don't Hide Everything in Bags
Sealing large amounts of untreated belongings without a treatment plan can create additional problems.
❌ Don't Leave Heat-Sensitive Items
Plastic fittings, aerosols, waxes, medicines and specialist equipment need appropriate consideration.
❌ Don't Guess
If you're uncertain about an item, ask MothKill before removing it or leaving it in place.
Do You Need to Pull Furniture Away From the Walls?
Don't follow an arbitrary measurement from an online checklist unless MothKill has asked you to.
The important requirement is that the treatment team has suitable access and can manage airflow around important areas.
We may reposition furniture ourselves as part of the treatment process.
Clear excessive clutter and make the room accessible rather than attempting to redesign the room before we arrive.
Do You Need to Empty Wardrobes and Drawers?
This depends on the treatment plan and the contents.
Do not automatically move everything from an affected wardrobe into another room.
If items need removing, laundering or separating, follow the instructions provided for your treatment.
Doors and drawers may need to be opened or repositioned during treatment to improve airflow and access.
Do You Need to Remove Smoke Alarms?
Do not dismantle, disable or remove fire-safety equipment unless specifically instructed by the treatment team and it is appropriate to do so.
MothKill will manage treatment considerations involving alarms or sensors as necessary.
Do You Need to Pre-Heat the House?
No general pre-heating rule should be followed unless MothKill specifically asks you to do something before arrival.
Our heating equipment and treatment process are planned around the property and treatment requirements.
What Happens on Treatment Day?
Final Check
The treatment area and preparation are checked before heating begins.
Equipment Setup
Heating equipment, ducting, industrial fans and temperature monitoring equipment are positioned.
Controlled Heating
Clean heated air is introduced and circulated through the treatment area.
Temperature Monitoring
Multiple sensors allow temperatures in different locations to be monitored as the treatment progresses.
Thermal Exposure
The treatment is managed to achieve sufficient thermal exposure in the areas being treated.
Completion and Aftercare
MothKill will advise when you can return and explain any monitoring or follow-up required.
What Happens After Bed Bug Heat Treatment?

Depending on the treatment plan, this may include:
- continued monitoring;
- inspection after an appropriate interval;
- checking for physical evidence of continuing activity;
- powder or other follow-up measures where appropriate; and
- additional treatment if required.
Don't judge success from bites alone. Skin reactions can be delayed and vary considerably between people.

Does Good Preparation Guarantee Bed Bug Eradication?
No responsible preparation guide should promise that.
Good preparation helps:
- give the technician access;
- improve airflow;
- reduce avoidable obstructions;
- protect heat-sensitive belongings; and
- support effective temperature management.
Successful treatment also depends on factors such as the extent of the infestation, property layout, treatment coverage, thermal exposure and whether bed bugs are subsequently reintroduced.
⚠️ The Most Important Rule
Follow the preparation instructions supplied for your actual treatment.
Internet checklists are general guidance. Your technician knows the equipment being used, the areas being treated and the treatment plan for your property.
Bed Bug Heat Treatment Preparation FAQs
Do I need to bag all my clothes before heat treatment?
No, not automatically. Follow the instructions for your treatment. Unnecessary bagging and moving of belongings can make preparation more complicated and may move potentially infested items into untreated areas.
Do I need to wash all my clothes?
Not necessarily. MothKill will advise what needs laundering or otherwise managing. Always follow garment care instructions.
Should I throw my mattress away?
No. A mattress does not normally need to be discarded simply because bed bugs are present. Mattresses and bed frames are important parts of the treatment area.
Can I leave laminated furniture in the room?
Tell MothKill about laminated or MDF furniture before treatment. Adhesives and surface finishes can be vulnerable to elevated temperatures, so individual items may need consideration.
What about plastic blinds?
Plastic blinds and their components can potentially soften or distort during heat treatment. Point them out before treatment so they can be assessed.
Can plastic clothes rails stay?
Tell us about lightweight plastic clothes rails and similar fittings. Depending on the material, removal may be appropriate.
Can electronics stay during heat treatment?
Some electronic equipment may be suitable to remain while other specialist or heat-sensitive equipment may need removing. Discuss expensive or unusual electronics with MothKill beforehand.
Can pets stay in another room?
Pets cannot remain in an actively heated treatment area. Whether another part of the property is suitable depends on the treatment plan, so arrange this with MothKill beforehand.
Can I stay at home during treatment?
You cannot remain in rooms while they are being actively heat treated. MothKill will explain the arrangements for your particular property and when treated areas can be re-entered.
Do I need to move furniture away from the walls?
Don't follow a fixed distance unless MothKill has specifically asked you to. Clear excessive clutter and provide good access. Furniture can be repositioned as necessary during treatment.
Does heat treatment kill bed bug eggs?
Yes. Bed bug eggs can be killed when sufficient thermal exposure reaches them. This is why temperature distribution, exposure time, airflow and monitoring are important.
Is one heat treatment always enough?
No treatment should be described as automatically successful in every property. Treatment outcome depends on factors including coverage, thermal exposure, the extent of infestation and the possibility of later reintroduction.
Good Preparation Helps Us Treat the Property Properly
You don't need to turn your home upside down before MothKill arrives.
The goal is controlled preparation — not emptying the property.
Keep potentially infested belongings within the treatment plan, clear excessive clutter, identify heat-sensitive items and make sure people and pets are safely away from the heated area.
If you're unsure about something, ask before treatment day. We'd much rather answer a preparation question than have you unnecessarily remove an item or leave something heat-sensitive behind.
