General Facts

Why do I have flour beetles?

Flour beetles survive Canadian winters in warm granaries, farms, mills, warehouses, supermarkets, and homes, where they can find the ground grain they need to survive.

They only eat finely milled starches like flour and meal, and do not feed on whole kernels. In homes, flour beetles thrive in crevices inside pantries and cabinets, where food spills infiltrate.

As well, female flour beetles like to lay about 450 sticky, white eggs directly onto a food source, on which the larvae can feast when they hatch.

How worried should I be about flour beetles?

During a flour beetle infestation, any product they have invaded is contaminated, with dead beetles, cast off skins, fecal pellets, and liquid waste, and should be discarded.

A flour beetle infestation can also give off a sharp, unpleasant odour. Not only that, live flour beetles cause moisture to build inside stored items, which can lead to mold growth, and severely infested milled grain can also appear pink, due to the sheer number of insects within.

Since the average flour beetle lives for a year, your pest problem may not be so easy to eradicate. For peace of mind, you need a professional pest control service.

How can I prevent flour beetles invading?

Inspect cereals, flour, cake mixes, and noodles, Store all milled grain and starches in airtight containers, Inspect pantries regularly for pest activity, Always clean up spilled flour and food products, Check hidden areas around appliances, Regularly vacuum pantries and cabinets, Check cracks and crevices for beetles
