Fumigation involves using an approved fumigant tablet (such as aluminium phosphide for rabbits) that disperses toxic gas. This method is implemented after a baiting and ripping program, which has reduced large rabbit numbers.

To undertake a program, use a smoker machine to identify all entrance holes of a warren system, mark entrances with flagging tape and then systematically apply rabbit aluminium phosphide tablets with moist newspaper to each hole. Then close/seal every entrance with a hand shovel and soil. Ensure each entrance is sealed and soil compacted.

Always wear Personal Protection Equipment and follow product labels for storage and handling.

All year though more effective when soils are moist and rabbit numbers are low.
Check the day after treatment and again one week later. Re-treat any open entrances and periodically check for new activity.

Fumigation is a cost-effective method for low entrance numbers It is easily transportable and is a fast solution if entrances re-open. However, the warren remains intact underground and rabbits can easily recolonise. Fumigation is difficult in rocky areas and around tree roots where it may be hard to seal entrances.

This method is labour intensive. It is a useful follow-up treatment for isolated warrens with low entrance numbers. It does not destroy the warren structure, making the treated site vulnerable to re-colonisation. Warrens can be potentially used by native animals such as snakes and wombats. It is important to inspect the hole before fumigating is used to avoid harm to off-target species.

Aluminium phosphide is a scheduled 7 poison and is a danger to other species and can harm the person laying the bait. An Agricultural Chemical User Permit (ACOP) is required to purchase fumigation tablets and can only be used by a ACUP holder or under direct supervision of an ACUP holder.

Cultural Heritage Awareness

Landholders must be careful to avoid further damage to the environment (including waterways) and Aboriginal cultural heritage sites when using machinery.
