The home flea killer from Zero In will monitor and control fleas in your home over a 10 m radius. Poison free, odourless and safe to use around children and pets, it attracts fleas via a 7 W heat lamp. Fleas are lured onto a sticky disc which they are then trapped in. Quick and easy to set up, it comes with three sticky discs (trap refills are available - product code: ZER019) and can be used continuously for 24-hour protection. Change the sticky discs every 2-4 weeks as a fresh pad is more effective. For best results, place the flea killer unit on the floor near to where your pets spend a lot of time.
