A Guide to Food Insects

What are Food Insects?

Food insects are insects that can spoil and thrive from rotting or left-out food. They share a striking resemblance with other common insects and exhibit similar movements and flight patterns. These insects are typically found in grains, cereals, flour, dried fruits, nuts, spices, and other similar food products.

This similarity often leads to misidentifications, as they can be mistaken for ordinary insects. What sets them apart, however, is their ability to cause food spoilage, leading to rotting. This behaviour distinguishes them from other insects typically found in homes during warmer months.

What Causes Food Insects?

There are a variety of reasons these bugs can spread and thrive in a home or business. Here are some of the reasons:

Laying Eggs on Food

Insects such as beetles and moths lay their eggs on or near food items. When these eggs hatch, the larvae feed on the food, causing damage and contamination.

Poor Storage Practices

Improper storage of food products can attract insects. If food is not stored in airtight containers, it becomes susceptible to infestations. Insects can easily access open containers and lay eggs or feed on the food.

Moisture and Humidity

Insects thrive in environments with higher humidity levels. Storing food in damp or humid areas can encourage insect infestations. Moisture can also cause food products to become mouldy, attracting insects.

Grain Processing Facilities

Insects might infest food products during the processing and packaging stages. If the facilities are not properly maintained and cleaned, insects can find their way into the products.

Cross-Contamination

Insects can move from one infested food item to another. If you have an infested product in your pantry, it’s possible for the insects to spread to nearby foods.

Natural Attraction

Some insects are naturally attracted to certain types of food, especially grains, cereals, and dried fruits. They can find their way into your pantry if these items are not stored securely.

Long Storage Times

Food items that are stored for a long time are more likely to become infested. Insects have more opportunities to find and infest older products.

Lack of Regular Cleaning

Regularly cleaning your pantry and food storage areas can help prevent insect infestations. Crumbs and food particles left behind can attract insects.

If you suspect a food insect infestation, the first course of action is to check your food and dispose of anything that is past its use-by date. Then, thoroughly clean the area.

If you do have a problem with food going off incredibly quickly, it is vital that you bin those products and any food that is in that area. You should also seek professional advice because it may well be that other food in your home is already contaminated.

It is also important to call a technician because you cannot use over-the-counter sprays for insects because they involve food.

The presence of these bugs can pose significant health risks as they easily contaminate food, potentially leading to disease transmission.

For food-producing companies, contaminated products must be discarded, resulting in substantial waste and financial challenges.
