11g ready-to-use insecticidal smoke generator containing 13.25% w/w permethrin for controlling flying and crawling insects throughout enclosed spaces.

Fortefog P Midi Fumer is a ready-to-use insecticidal smoke generator designed for treating larger enclosed areas where conventional spraying may be difficult or impractical. Once ignited, it releases insecticidal smoke throughout the treatment space, helping the active ingredient reach cracks, corners and other difficult-to-access areas.

The 11g Midi Fumer contains 13.25% w/w permethrin and controls a broad range of flying and crawling insects, including houseflies, cluster flies, fruit flies, mosquitoes, wasps, moths, fleas, bedbugs, ants and cockroaches.

With coverage of up to 400m³ for flying insects, the Midi provides considerably greater treatment capacity than the smaller 3.5g Mini, making it a practical choice for medium-sized enclosed treatment areas.

Why choose Fortefog P Midi Fumer?

  • No dilution required – supplied ready to use with no mixing or spraying equipment required.

How to use Fortefog P Midi Fumer

Before treatment, calculate the number of fumers required according to the volume of the enclosed space and the target pest. Close windows and doors and prepare the treatment area in accordance with the product label.

Remove people and animals from the treatment area and follow the precautions stated on the product label for fish, food, plants and other sensitive items. Position the fumer securely on a suitable heat-resistant surface before ignition.

Remove the lid and ignite the blue touch paper. If several fumers are required, position them before starting and ignite the unit furthest from the exit first, working back towards the door. Leave the treatment area immediately after ignition.

Keep the area closed for the treatment period specified on the current product label. After treatment, ventilate the space thoroughly before re-entry. Heavy infestations may require repeat treatment in accordance with the label directions.

Always read and follow the product label before use. Use biocides safely.
