Fortefog Fumers are permethrin-based insecticide foggers.
 
Often pests will hide in nooks and crannies around the room, especially when there are large numbers on the plants. The smoke from these “candles” will seek them out wherever they hide. Turn off extractor fans, cover the carbon filter,tape over all gaps in flooring, doors and chimneys. Place the fumer on a heat-resistant base and light the fuse. Leave for several hours or overnight before entering the room again.
