Spray what you can reach. Smoke what you can’t.
A proper coop clean-out has two halves. The spray-down covers everything you can touch: surfaces, perches, nesting boxes, feeders, drinkers and water lines. But disease doesn’t only live where the cloth goes — it sits in the cracks between boards, behind the nesting boxes, up in the roof space. That’s the smoke’s job: it fills the whole airspace and settles on every surface as it cools, finishing what the spray started. Commercial poultry sheds run exactly this sequence at every clean-out; this kit is the same two steps, sized for a backyard.
What’s included:
- 1× Virkon S Disinfectant 50g — mixes into the spray for the wipe-down stage, as the label directs
- 1× Freezone Big Smoke OPP Disinfectant 30g — treats an enclosed space up to 30m³
The two-step clean-out
- Step 1 — clean and spray. Bedding out, surfaces scrubbed, then the Virkon S spray over surfaces, feeders, drinkers and water lines.
- Step 2 — fumigate. Bedding and equipment back in place, then the Big Smoke tin finishes the job — treating the air, the fresh litter and every surface at once, 24–48 hours before the birds return.
Step by step, both halves: cleaning the coop and disinfecting it once it’s clean.
Plan it around one night — whatever your flock size
The maker’s directions are 24–48 hours between lighting the tin and the birds going back in — so the full reset is a job you plan: do the clean and spray during the day, then the flock sleeps somewhere else that night. A handful of chooks: a pet carrier or a dog crate in the garage (chickens move easily after dark). A dozen or twenty: a secure run with a temporary roost for the night. A chicken tractor or mobile chicken coop with a big flock: do one house at a time — move the birds into the next unit for the night, smoke the empty one, then bring it back into use the following evening.
Whatever the size, decide where the birds will sleep before you light the tin — and with H5 about, that’s a plan worth working out well ahead of time, not on the day. Light in the evening, open the coop the next morning, air it through the day; they’re back on the roost the following evening.
When to run the full reset
- The annual deep clean — most keepers pick the end of winter, before spring laying
- After illness has been through the flock
- Before new birds arrive, or after taking on a second-hand coop
Using it safely
- The smoke treats an empty coop — birds, pets and people out from lighting until it’s been aired well
- Gloves for both products; don’t breathe the smoke — light it and leave
- Sit the tin on a brick, paver or tile — never on bedding or timber, and never inside a bucket or pail
- Keep the tin away from ponds, fish tanks and waterways — the active is toxic to aquatic life
- Store both in original packaging, out of reach of children
Always read both labels and follow the directions for use. Australia-only delivery.
Goes with
- Big Smoke OPP 30g single — a second tin for the feed shed
