Johnson’s 4fleas Room Fogger is a veterinary-strength, total-release aerosol treatment designed to eradicate flea infestations and other crawling insects within the home. It utilizes a dual-action formula containing adulticides (Permethrin and Tetramethrin) to kill adult pests on contact, alongside an Insect Growth Regulator (S-Methoprene) to halt the development of flea eggs and larvae. This breaks the flea life cycle and provides long-lasting household protection.

How It Works
When activated, the can automatically discharges its entire insecticidal contents as a fine mist. This aerosol mist saturates the room, penetrating deep into carpet fibres, cracks, crevices, and soft furnishings where flea pupae and larvae typically hide.
Step-by-Step Usage Instructions
- Preparation: Thoroughly vacuum the carpets to encourage flea pupae to emerge from their cocoons.
- Clear the Area: Remove all people and pets from the room. Cover fish tanks tightly and turn off their air pumps.
- Seal and Open: Close all exterior windows and doors, but open interior cupboards and wardrobe doors to let the mist penetrate. Extinguish any naked flames or pilot lights.
- Positioning: Place the fogger upright in the centre of the room on a slightly raised surface (like a chair or table). Lay down old newspapers underneath the can to protect the surface.
- Activation: Point the nozzle away from your face at arm’s length and press down hard on the plastic actuator until it locks into place.
- Evacuation: Immediately leave the room and close the door behind you. Leave the room sealed for 2 hours while the fogger completely discharges and settles.
- Ventilation: After 2 hours, re-enter the room, open all doors and windows, and let the space air out thoroughly for at least 30 minutes before allowing pets or people back inside. Wash hands thoroughly after handling
