At Wessex Refrigeration Hire, we're seeing more and more clients — from homeowners to heritage trusts — turn to commercial freezers to solve their pest problems. This method is not only highly effective but also completely non-toxic, protecting your valuable items without the use of harsh chemicals.
This guide will walk you through everything you need to know about using a commercial freezer to eradicate clothes moths, carpet beetles, and bed bugs for good.
Why Use a Commercial Freezer for Pest Control?
Before we dive into the "how," let's explore the "why." Using freezing as a pest control method offers several compelling advantages over traditional chemical sprays and fumigation.
Extreme cold is lethal to pests at every stage of their life cycle — from eggs and larvae to adults. A sustained deep freeze ensures no survivors.
Treat delicate textiles, children's toys, and bedroom furniture without introducing harmful chemicals into your home environment.
Unlike chemical treatments that can stain or damage delicate fabrics like wool, silk, and leather, freezing is exceptionally gentle.
For multiple infested items — sofas, rugs, an entire wardrobe — renting a walk-in freezer is often more affordable than repeated chemical treatments.
Understanding the Enemy: Moths, Beetles & Bed Bugs
To defeat these pests, you need to know what you're up against. While they all cause damage, their habits differ slightly.
Clothes Moths
It's not the adult moths that cause damage, but their larvae — tiny grubs that feast on natural fibres containing keratin: wool, silk, fur, feathers, and leather.
Tineola bisselliellaCarpet Beetles
Larvae known as "woolly bears" consume natural fibres, lint, hair, dead insects, and some stored food. Often found along skirting boards and inside upholstered furniture.
Anthrenus verbasciBed Bugs
Feed on the blood of humans and pets. Notoriously difficult to kill — they hide in mattresses, bed frames, sofas, and soft furnishings and spread quickly.

The process for treating these three pests is very similar. The key to success is meticulous preparation and ensuring a sustained, deep freeze.
Inspection & Isolation
Carefully inspect all susceptible items. For moths and beetles, look for tiny holes, webbing, shed larval skins, or larvae themselves. For bed bugs, check mattress seams and furniture crevices for small reddish-brown stains or tiny black spots.
As you identify infested items, immediately place them into heavy-duty plastic bags and seal them tightly. This prevents pests from escaping and spreading while you prepare.
Prepare Your Items for Freezing
Thoroughly vacuum all items before bagging them — use a crevice tool to get deep into seams and folds. This removes many adult insects and larvae, making the freezing process even more effective.
The Freezing Process
This is where a commercial freezer makes all the difference. A domestic freezer often lacks the space and power to reach the necessary temperatures for large or multiple items.
Thawing & Post-Treatment
Remove the bags from the freezer and let them thaw slowly at room temperature for at least 24 hours before opening.
Once fully thawed, remove the items and inspect them one last time — give them another vacuum for good measure.
Prevention is the Best Cure
You've won the battle — now win the war. To prevent a future infestation:
- Clean regularly — vacuum carpets, rugs, and upholstery frequently, paying close attention to corners and edges.
- Store properly — keep out-of-season clothing in airtight garment bags or plastic containers.
- Use natural repellents — place cedar blocks or lavender sachets in your wardrobes and drawers.
- Monitor for activity — regularly inspect your belongings for new signs of pest activity. Catching it early is far easier than dealing with a full-blown infestation.
