Usually arrives inside something you bought — stored grain, pulses or spices — and spreads from that one packet across the store cupboard.
Stored-product beetles chew through paper and thin plastic, so an unopened bag is no guarantee. They favour forgotten corners — the back of a pantry, a sack of rice bought in bulk, spices kept for a season — and breed continuously in a warm kitchen.
They don't bite or spread disease, but infested food has to be thrown away, and in a restaurant or store the loss and the inspection consequences are far larger than the pest itself.
We trace the source packet first, since treating the room while the infested sack stays on the shelf solves nothing. Infested stock is removed, shelving and cracks get a residual treatment, and pheromone monitors confirm afterwards that nothing is still breeding.
Practical steps that make a repeat infestation far less likely after treatment.
Decant rice, flour and pulses into airtight containers as soon as you get home
Use older stock first and date anything bought in bulk
Check the back of the pantry monthly — infestations start in the packet nobody opens
Wipe shelf cracks and corners after any spill of dry goods
The things people ask us most before booking this treatment.
Usually they were already inside when you bought it, or they chewed in — stored-product beetles get through paper and thin plastic easily. An unopened bag is no guarantee, which is why decanting into airtight containers works so well.
Anything infested, yes — but not necessarily the whole cupboard. We identify which packets are affected and which are clear, then treat the shelving and cracks so the next packet doesn't go the same way.
Decant rice, flour and pulses into airtight containers as soon as you get home, use older stock first, and check the back of the pantry monthly. Infestations almost always start in the packet nobody opens.
