For best results fumigate in the late afternoon and leave the treated area for a minimum period of 2 hours.
1. Consider how many fumers you need for the room to be treated (consult 'Rate of application'). Heavy infestations may require more than one application.
2. Clear people and animals including fish from the room before use.
3. Place canister(s) spaced out on the floor surface on a heat resistant surface e.g. a plate on top of a sheet of aluminium foil 50cm x 50cm.
4. Make the area to be fumigated as smoke tight as possible by closing all windows etc.
5. Open canister(s) and light the fuse on the canister furthest from your exit point first, then light the next fumer and move towards your exit point. Close the door on exit, it is not necessary to seal the door with tape.
6. Leave for at least 2 hours but preferably overnight and then ventilate the room thoroughly.
7. For severe infestations fumigate 3 times at 5-to-7-day intervals.
