Johnson's Guardian Home Flea Spray

Fleas share a house with a surprisingly wide cast of other insects, which is why a spray built for "household use only" tends to list more than fleas on the can — ants, cockroaches, bed bugs and mosquitos are all fair game for the same water-based formula.

This is a household-use-only spray, and Johnson's are explicit it is not for use on animals. It's a water-based advanced micro-emulsion insecticide that kills fleas along with flying and crawling insects including flies, mosquitos, cockroaches, ants and bed bugs. It controls fleas for up to 6 months and other crawling pests for up to 8 weeks, and it's designed as a crack-and-crevice or spot treatment, or as a direct spray onto surfaces insects walk or land on. It comes in a recyclable trigger-spray bottle, at 500ml.

• 500ml recyclable trigger-spray bottle
• Water-based advanced micro-emulsion insecticide
• Kills fleas plus flies, mosquitos, cockroaches, ants and bed bugs
• Controls fleas for up to 6 months
• Controls other crawling pests for up to 8 weeks
• Household use only — not for use on animals

On the two different timeframes. The 6-month figure is specifically for flea control, while other crawling pests are covered for up to 8 weeks — worth knowing if you're treating a mixed problem, since the flea protection will outlast the rest. It is not for use on animals under any circumstances.

Who it's for: owners dealing with fleas alongside other household insects — ants or cockroaches as well as fleas — who want one spray that covers both rather than buying separate products.
