Moth Heat Treatment UK

Why heat treatment is the best moth solution in the UK

Moths are one of the most stubborn household pests in the UK. Clothes moths and carpet moths hide deep inside wool, cashmere, silk, upholstery and even behind skirting boards, where sprays and powders rarely reach. Worse, eggs and larvae are often protected inside fabric fibres, so chemical treatments usually need multiple visits — and the infestation keeps returning.

Heat treatment works differently. By raising the temperature of the affected rooms to 60–65°C and holding it there, every life stage of the moth is destroyed simultaneously. Eggs, larvae and adult moths cannot survive, so the infestation ends in a single day.

The benefits of chemical-free moth heat treatment

• No residue on fabrics. Nothing is sprayed onto clothing, carpets or upholstery, so there is no chemical smell or stain risk.
• Reaches hidden moths. Heat penetrates deep into wardrobes, drawers, mattresses, rugs and behind fixtures where sprays cannot reach.
• Safe for sensitive households. No pesticides means no risk for children, pets, allergy sufferers or anyone with asthma.
• Single visit. Most moth problems are resolved in one day rather than weeks of repeated chemical visits.
• Protects delicate textiles. Wool, cashmere, silk carpets and antique fabrics are treated without physical damage or chemical exposure.

The five stages of a moth heat treatment visit

1. Inspection and survey

We identify the species, locate larvae and damaged textiles, and mark out harbourage areas such as wardrobes, under beds, rugs and upholstered furniture.

2. Preparation guidance

We advise on any heat-sensitive items to remove — aerosols, candles, oil paintings, certain plastics and houseplants. For the best possible results, we ask that as much clothing as possible is hung on clothes rails in the largest room so our technicians can circulate the heat evenly around each garment. This allows warm air to flow freely through sleeves, collars and folds where moth larvae and eggs often hide. Clothing left in drawers or tightly packed wardrobes will not receive the same level of heat penetration, so allocating the biggest room for hanging rails makes a significant difference to the success of the treatment.

3. Deployment

Industrial heaters and high-volume fans are positioned to distribute heat evenly. Door gaps are sealed and wireless temperature sensors are placed in the coolest spots.

4. Ramp and dwell

Air temperature rises to 60–65°C and is held once the coldest sensor reaches target. We monitor continuously with thermal imaging and probes to ensure no cold pockets remain.

5. Cool-down and handover

Equipment is removed and the room cools to a safe temperature. You receive a treatment report and guidance on preventing future moth problems.

What types of moths we treat

Our heat treatment service covers the most common moth pests found in UK homes and businesses, including:

• Clothes moths — damaging wool, silk, fur, feathers and stored textiles.
• Carpet moths — feeding on wool carpets, rugs and underlay.
• Case-bearing clothes moths — leaving small silk cases on fabrics and skirting boards.
• Stored-product moths — infesting pantries, food storage and commercial kitchens.
