Pantry & stored product pest control

What you're dealing with
Indian meal moths, sawtoothed grain beetles, flour beetles and drugstore beetles arrive inside packaged goods from the supply chain — they are almost never a reflection of housekeeping.
Larvae chew through paper, cardboard and thin plastic, so intact packaging is not proof a product is clean. A single overlooked bag of flour or birdseed sustains an entire infestation.
Confirm itSigns to look for
- Small moths flying in a lazy, zig-zag path in the kitchen
- Silken webbing in dry goods, particularly at the surface of grain products
- Small beetles in cupboards, drawers or on shelving
- Larvae crawling up walls and along the ceiling line away from the source
How we treat it
- 01Systematic inspection of every dry good, including pet food, birdseed, spices and decorative grain items
- 02Removal and disposal of infested product
- 03Cleaning and vacuuming of shelving, cracks and shelf-bracket holes
- 04Crack-and-crevice treatment of harbourage, never of food-contact surfaces
- 05Pheromone monitoring where confirmation over time is needed
How to prepare
- Empty affected cupboards completely before we arrive
- Check pet food, birdseed and decorative items — these are the usual overlooked sources
- Keep any infested product bagged so we can identify the species
What to expect
- Visit oneInspection, then treatment of every harbourage area we find. You get a written record of what was applied and where.
- The days afterResolved as soon as the source is removed. Monitoring confirms nothing was missed.
- Follow-upOn request — we return whenever the situation calls for it.
Why we treat it this way
Why we find and discard the source rather than spray the pantry
The infestation lives inside a package. No surface application reaches larvae inside a bag of flour, and no one wants insecticide near food anyway. Finding the infested item and removing it is the treatment; everything else is supporting work.
Why every package gets checked, not just the obvious one
Larvae move between packages and chew through paper, cardboard and thin plastic. The bag you found is frequently not the only one, and a single missed package restarts the whole thing in a month.
Why the empty shelf gets treated, not the food
Once the pantry is cleared, cracks, shelf edges and corner joints get treated — that is where larvae wander to pupate. Product goes on structure, never on food or food-contact surfaces.
What makes it worse
These are the things we most often arrive to find already done. None of them are unreasonable instincts — they just backfire for reasons that are not obvious.
Throwing out the obvious package and considering it done
The most common reason this recurs. Moths seen flying weeks later are almost always from a second package that was never checked.
Spraying inside the pantry
Ineffective against larvae inside packaging and inappropriate around food. It also creates a residue problem in a space where you prepare meals.
Assuming it came from a dirty kitchen
It almost always arrived in a sealed product from the store, or in birdseed or dry pet food kept in the house. This is a supply-chain issue, not a housekeeping one.
What's different here
Birdseed and dry pet food stored in garages, porches and basements are the most common Winnipeg entry route, and they are often overlooked entirely because people do not think of them as pantry items. Bulk buying and long storage — sensible in a city with a serious winter — extends the window in which a slow infestation can develop unnoticed.
