Johnsons 4fleas room fogger– Complete Dual Action Household Treatment (Twin Pack)
Stop flea infestations in their tracks with the Johnsons 4fleas room fogger Twin Pack. Engineered for fast, complete room coverage, this dual-action household flea fogger eliminates adult fleas, ticks, and other crawling insects while breaking the flea life cycle to prevent re-infestation for up to 7 months.
Formulated with powerful active ingredients including Permethrin, Tetramethrin, and the Insect Growth Regulator (IGR) S-Methoprene, the automated room fogger penetrates deep into carpets, soft furnishings, and pet bedding where fleas hide and lay eggs. The easy-to-use, lock-down actuator discharges the entire aerosol content automatically, leaving no lingering odour or residue.
Each twin pack contains two 100ml cans, providing complete coverage for up to 70m² (35m² per fogger).

-
Placement: Place the fogger on an elevated surface (e.g., a chair or table) protected with newspaper beneath the can.

Activation: Keeping at arm’s length, point the top away from your face and press down firmly on the actuator until it locks into place.

Treatment: The fogger will automatically discharge completely. Immediately leave the room and keep all doors and windows closed for 2 hours.

Ventilation: After 2 hours, open all doors and windows to thoroughly air the treated area for at least 30 minutes before re-entry.
Tip: For heavy infestations or covered areas under low furniture where fog cannot reach, combine with Johnson’s Household Flea Spray for spot treatments.
