Live season · October is not too late

One mouse in September is a kitchen in January if the gap stays open. We inspect, treat what is there, and close the 6 mm joints Calgary freeze-thaw opens.

The hole

## You should not have to Google droppings at midnight.

Mice move with the first cold nights, often late August into September. They use the garage weatherseal, the pipe sleeve, the deck ledger, and every joint that already takes water.

Most homeowners spray the wrong thing and leave the hole open. Framework inspects, treats what is actually there, and helps you seal the gaps so the problem does not move back in with the frost.

A house should be quiet, sealed, and yours again.

## 6 mm, freeze-thaw, and first frost

A mouse needs a 6 mm gap. Calgary freeze-thaw opens that gap at the garage seal, the pipe sleeve, and the rim joist. First hard frost is usually mid-September. Proof the house before that night, not after the ceiling starts ticking.

The plan

## You show us what you saw. We name it, treat it, and close the gap.

1. 01
  ### Show us what you saw
  Call, text a photo, or book. Tell us the pest, the evidence, kids or pets, and how fast you need us.
2. 02
  ### We inspect and name it
  Identify the pest, map the entry, and separate a retail fix from a service job. No guessed treatment.
3. 03
  ### Treat, close gaps, follow up
  Least-risk labelled treatment, an exclusion list, and a warranty window. Aftercare in writing.

If we go

## The cutting board stays clean.

Gaps on a list, then closed. Hardware that survives Chinooks. Aftercare in writing. You sleep. Guests come over.

Questions

## Mouse-proofing, plainly.

### When should I mouse-proof a house?

August into September, before the first stretch of cold nights. October is not too late. January is still worth doing. One mouse in September is a kitchen in January if the gap stays open.

### Can you just put bait stations in the garage?

We can reduce a population that is already inside. If the 6 mm joint stays open, you have bought a subscription. Mouse-proofing is the joint, then the population.

### Is mouse-proofing a one-off?

The first visit is inspect, treat, close. Most houses then sit on a seasonal program so freeze-thaw does not reopen the same joint. Written spec. You can leave. The file stays yours.
