Kitsilano — Eastern grey squirrel family with three kits, humane exclusion timed around weaning

A Kitsilano homeowner with April attic noises had an Eastern grey squirrel mother nursing three kits. BC Wildlife Act requires humane timing; we held exclusion until kits weaned naturally (four weeks), then one-way-door sealed permanently.

Section 1

The situation

Homeowner called reporting scratching and chittering sounds from the upstairs ceiling at sunrise. She had been told by another company that they could trap and remove immediately for a flat fee. She was uncomfortable with the ethics of trapping and called us for a second opinion. Initial diagnostic call indicated likely Eastern grey squirrel (Sciurus carolinensis), which is non-native to BC but still covered under the BC Wildlife Act for humane treatment considerations, particularly for dependent young.

Section 2

The assessment

On-site inspection confirmed an active squirrel entry at a gable vent on the west elevation with visible chewed edges and greasy rub marks. Attic access confirmed a nesting area with insulation pulled aside and a visible mother plus three kits approximately 2-3 weeks old. Kits at this age are not weaned and cannot survive independently. Excluding the mother at this stage would have left three kits to die in the attic — a welfare outcome we do not create.

Section 3

The intervention

Four-week hold protocol. Week 0: sealed all other potential entry points around the building envelope with hardware cloth, leaving only the active gable vent open, so no other wildlife entered and the mother had a single known exit. Bi-weekly site inspection to confirm mother was still actively carrying food and kits were progressing. Week 4: kits observed outside the nest in the backyard tree, confirming weaning. Installed one-way door at the gable vent. Monitored for 7 days to confirm all family members had exited. Sealed the gable vent permanently with hardware cloth and new matching exterior trim. Total duration start to finish: 5 weeks.

Section 4

The outcome

Zero orphaned kits. Zero squirrels re-entered the attic at 90-day and 180-day follow-up. The homeowner received written documentation of the humane protocol used. We also recommended tree-trim work to reduce roof access, which the homeowner scheduled for the following spring. The project took longer than a trap-and-remove would have taken, but it was the right outcome and it held permanently.

Section 5

Why trap-and-remove was the wrong option

Trap-and-remove during nursing season causes orphaned kits that die in the wall cavity, which triggers a carcass decomposition problem worse than the original squirrel issue — plus the ethical cost of killing three kits. BC AnimalKind accreditation standards, which we operate to, explicitly require humane timing around dependent young. For the homeowner, the four-week wait was a minor inconvenience; for the three kits, it was the difference between a healthy life in the backyard cedars and death in a wall cavity.

Customer outcome

Another company told me they'd just trap and remove for a flat fee. The Wild Pest told me there were babies and we needed to wait. That was the right answer. I paid a bit more and took a bit longer, but I didn't kill three baby squirrels to solve my attic problem.
