Bayer Coopex Residual Insecticide 25g Sachet

A long-lasting barrier against household pests, mixed up from a single sachet. Coopex is a water-dispersible powder that, once sprayed, keeps working on undisturbed surfaces for up to four months.

It controls a wide range of insect pests indoors and out, and it's cleared for use well beyond the home, in places like hotels, food processing areas and hospitals. The active is permethrin 25:75 at 250 grams per kilogram, a proven synthetic pyrethroid.

It's odourless and won't stain or mark the surfaces you treat, so you can use it around the house without the lingering smell. Mix it per the label and spray a coarse band where the pests track, along walls, skirting boards and into cracks and crevices.

The mixing rates are in the tabs below. Always read the label first, and ask us in store if you're unsure where to treat.
