Do you worry about pest infestations in your food processing facility? You may have good reason to be concerned. That’s because a wide variety of pests can be attracted to the nutrient, shelter and moisture sources that a food manufacturing environment provides. Pests can cause disruption, productivity decline and even profit loss due to contaminated products and possible structural and equipment damage.

Signs of Pest Infestations in Your Food Processing Facility

It’s good to be aware of potential pest issues so you can nip infestations in the bud. Many types of pests, especially stored product pests, can infest the product before you even receive it. Most often found in the egg or larvae stages, these infestations are very difficult to detect until they have developed. Common stored product pests include moths, weevils and many other types of beetles. They can attack a variety of different types of food items such as whole grains, wheat, corn, barley, rice, beans and nuts.  Stored product pests often have widespread infestations with more than one source, so pinpointing and treating them can be challenging.

Many other pests, like cockroaches, are nocturnal and prefer to avoid human contact, so you may not know they are there until infestations are out of control. Knowing some of the signs that pests may be present in your facility can help you take quick action before populations increase or product damage occurs.
