Raid Flea Fogger — 3-Can Pack Indoor Fogger, Kills Fleas & Hatching Eggs, Up to 4 Months Residual

Raid Flea Fogger Plus Killer is an indoor whole-room fogger that kills adult fleas and hatching eggs and provides residual control for up to four months.

When fleas invade carpeting, baseboards and pet areas, treating only the animal or visible bugs often isn’t enough. These water-based foggers release a fine mist designed to reach cracks, fabrics and hidden corners to interrupt flea life cycles at the source. The three-can pack lets you treat multiple rooms or reapply when needed during peak flea season; follow label directions and safety steps for best results.

How long does protection last after using this fogger?

After a single treatment, the active ingredients leave a residual effect that can help suppress flea activity for up to four months under typical household conditions. Residual efficacy depends on foot traffic, vacuuming, and how often surfaces are washed. For sustained control in high-traffic or heavily infested rooms, plan follow-up treatments and combine with pet flea prevention.

• Labelling indicates up to four months' residual activity
• High-traffic areas may need more frequent reapplication
• Complement with veterinarian-recommended pet flea products
• Cleaning or shampooing carpets reduces residual life

What size room will one fogger treat and how do I prepare the space?

A single can treats an unobstructed room up to 24' x 20' with an 8' ceiling (about 3,840 cubic feet). Clear food, dishes and sensitive items, cover electronics and delicate surfaces, and remove pets and plants before use. Extinguish open flames and turn off fans; follow the label’s instructions for timing and ventilation to ensure safe re-entry.

• Treats up to 24' x 20' x 8' per can
• Do not use in rooms smaller than 5' x 5'
• Remove people, pets and cover exposed items
• Allow 2 hours fogging time, then ventilate 2 hours

Will the fogger also stop flea eggs from hatching?

This fogger targets both adult fleas and hatching eggs, aiming to break the flea life cycle within treated areas. The formulation is designed to reach larvae and eggs in hidden locations where spot treatments can miss. Complete lifecycle control often requires treating all infested rooms and combining environmental control with on-pet products.

• Contains agents active against eggs and newly hatched fleas
• Reaches cracks, upholstery and carpet fibers where eggs hide
• Works best when all rooms with pets are treated
• Follow label instructions for safe use and re-entry

How should I re-enter and reintroduce pets after treatment?

After initiating the fogger, remain out of the treated area for the two-hour fogging period, then ventilate the room for an additional two hours before anyone returns. Clean or replace pet bedding only after the ventilation period and once surfaces are dry. Pets should be on an appropriate veterinary flea prevention regimen before returning to the treated space.

• Stay out during fogging and initial 2-hour ventilation
• Air out rooms for at least two hours before re-entry
• Do not let pets onto treated carpets until fully aired
• Treat pets with vet-approved flea control before returning

Who is this product for? Raid Flea Fogger Plus Killer is intended for homeowners and renters dealing with indoor flea infestations who need whole-room coverage and longer-lasting control on floors, fabrics and hidden cracks. It’s especially useful for multi-room treatment plans during flea season, for people who already use pet-directed flea prevention, and for anyone wanting a water-based fogger that treats both adult fleas and hatching eggs. Always read and follow label directions, safety precautions, and local regulations before use.
