Stored Product insects

Expert control of weevils, moths and beetles in stored agricultural commodities

Stored-product insects (SPI) can cause significant problems for businesses involved in food storage, processing, manufacturing, and distribution. Pests such as beetles, weevils, moths, and their larvae can infest products including grains, cereals, flour, dried fruit, nuts, spices, and other stored foods. Infestations can lead to contamination, product loss, reduced quality, and financial costs, as well as potentially damaging a business’s reputation. Pest Ex provides professional monitoring and control solutions to identify activity early, protect stored products, and help prevent infestations from becoming established.

Signs You Have a SPI infestation

Live insects or larvae found in food, packaging, cupboards, or storage areas.

Webbing or silk trails appearing across cereals, flour, grains, dried fruit, or other stored foods.

Damaged or contaminated packaging, including holes, dust, droppings, or shed insect skins.

Unusual odours or changes to food, such as clumping, discolouration, or products becoming unsuitable for use.

Why SPIs Can Be Damaging

Contaminate food stocks with larvae, droppings, shed skins, webbing, and other debris.

Cause significant product loss, with infested food often having to be discarded.

Spread between products and storage areas, allowing infestations to become widespread if not detected early.

Damage business reputation and compliance, particularly for food manufacturers, retailers, warehouses, and hospitality businesses.

 Trustindex verifies that the original source of the review is Google. Very impressed.  Bird proofed our home within a few days of first contact, even in terrible weather conditions.  Excellent customer service - returned our calls, did a quote promptly, responded when they said they would, turned up on time, and most importantly I've not heard any birds in eaves since.  Thank you

How we deal with
SPI infestations

Pest Ex takes a thorough, targeted approach to stored-product insect (SPI) infestations, beginning with an inspection to identify the pest species, source of the infestation, affected products, and areas where insects may be harbouring. We assess storage conditions and potential routes of spread before recommending the most appropriate treatment, helping to minimise product contamination and disruption to your business.
Our professional pest control measures are designed to eliminate active infestations and reduce the risk of recurrence. We also provide practical advice on stock rotation, hygiene, storage, and preventative monitoring, helping businesses identify future activity at an early stage and maintain effective long-term control.
