Grain Weevils in Kitchen Cupboards in Warsaw — How to Find and Remove Them
Small brown beetles in your groats or flour are a sign it's worth checking the whole cupboard — a guide for Warsaw residents.
Why are grain weevils a problem in the kitchen?
Small brown beetles in your groats or flour are a sign it's worth thoroughly checking the contents of your kitchen cupboard.
Contaminate food products
They feed in groats, flour, cereal flakes and other loose products.
Hard to notice in time
Their small size makes it easy to miss the first signs of infestation.
Spread quickly between products
From one infested package they can colonise an entire cupboard.
Can trigger allergic reactions
Larvae and shed skins can be an allergen for sensitive people.

- Small, brown beetles visible in groats, flour or cereal flakes
- Small holes or clumps in loose product packaging

Grain weevil or food moth? How to tell them apart
These two pests are often confused, since they feed on the same products:
| Grain weevil | Food moth | |
|---|---|---|
| Appearance | Small, brown beetle, about 2–4 mm | A small moth with an 8–10 mm wingspan |
| Damaging life stage | Both larvae and adult beetles feed | Only the larvae cause damage |
| Marks on products | Small holes and clumps in grains | Thread-like webbing and clumps in flour |
| How it moves around | Walks, rarely flies | Flies, visible in the air in the evening |
