SPI heat treatment
Stored Product Insects (SPIs) are a major risk to the UK food industry, contaminating products, damaging stock, and threatening compliance with food safety standards. Infestations in flour mills, warehouses, bakeries, and food factories can spread quickly, leading to costly losses and reputational harm.
At ThermoPest, we specialise in professional SPI pest control for food production businesses in London and nationwide. Using advanced heat treatment technology, supported by monitoring and ongoing pest management contracts, we deliver safe and effective control without the need for chemical fumigation.
See our Stored Product Insects information page for details on the most common pests affecting food businesses.
Why heat
Heat treatment is one of the most effective methods of controlling SPIs in food production environments. Unlike chemical fumigation or spraying, heat leaves no toxic residues, making it ideal for use around food storage and processing.

Our programme
At ThermoPest, we don’t just carry out one-off treatments — we provide integrated pest management (IPM) solutions for food manufacturers and storage facilities.
Step 1: Site Survey & Risk Assessment
We inspect your facility to identify the type of stored product insect, the scale of the problem, and high-risk areas.
Step 2: Heat Treatment
Our professional heaters raise the temperature of the environment to lethal levels for insects at all life stages.
Step 3: Monitoring & Prevention
We install and maintain SPI monitoring systems such as traps and detection points to track insect activity and identify risks early.
Step 4: Ongoing Contracts
For businesses under constant pest pressure, we offer regular pest control contracts (monthly, bi-monthly, or quarterly visits).
