Doff Flea Killer Powder 240g

Doff Flea Killer Powder 240g is a ready-to-use indoor insecticide powder that kills fleas, their larvae, and a wide range of other crawling insects in the home. The shaker-bottle format makes light work of treating carpets, soft furnishings, skirting boards and other harbourage points, and one 240g pack is enough to treat multiple rooms in a typical UK house.

This is a versatile crawling-insect powder, not just a flea treatment. The same 240g tub also controls carpet beetles, ants, cockroaches, earwigs, woodlice and other crawling insects in domestic premises, so it's a useful all-rounder to keep in the cupboard against a range of common household pests.

Where to Use

Sprinkle the powder lightly over the infected surface and into the harbourage areas where insects hide and breed. Pay particular attention to:

• Carpets, rugs and carpet edges (especially along skirting boards)
• Soft furnishings, pet bedding and the areas beneath furniture
• Cracks, crevices and gaps behind kitchen units and skirting boards
• Loft spaces, cellars and other dry, undisturbed areas
• Pet sleeping areas (do not apply directly to pets — see safety notes below)

How to Use

• Identify the problem: confirm activity in the affected room — fleas, ants, carpet beetles and the other pests listed all leave visible droppings, shed skins or live insects.
• Prepare the area: remove pets, children and pet food/water bowls. Cover fish tanks.
• Apply: shake the powder thinly and evenly over the surface, focusing on edges, cracks and harbourage points. A light dust is sufficient — do not pile it up.
• Leave in place: allow the powder to remain undisturbed for as long as practical (ideally 24–48 hours) so insects pick it up as they move through it.
• Vacuum: once activity has stopped, vacuum thoroughly to remove the powder. Dispose of the vacuum bag outside in a sealed bag.
• Re-treat: for severe flea infestations, repeat after 7–10 days to catch any newly hatched insects.

Frequently Asked Questions

Is this powder safe to use around children and pets?
The powder should be applied when children and pets are out of the room, and the area should be ventilated before they return. The child-resistant cap helps prevent accidental opening, but always store in a cool, dry place out of reach of children and pets. Do not apply directly to animals.

How long does Doff Flea Killer Powder take to work?
Most crawling insects are killed on contact with the powder, with a noticeable reduction in activity within 24–48 hours. For heavy flea infestations, a second application 7–10 days after the first is recommended to deal with any insects that have hatched from eggs since the initial treatment.

Can I use this powder on carpets, sofas and pet bedding?
Yes — it is designed for use on carpets, rugs, soft furnishings and along the edges of rooms where insects travel and harbour. Avoid applying directly to pets or to areas they may lick. Vacuum the powder up thoroughly after treatment.

Does it have a strong smell?
No. Doff Flea Killer Powder is a low-odour powder formulation, so it is well suited to living rooms, bedrooms and other indoor spaces where a strong chemical smell would be unwelcome.

Is it safe to use near fish tanks or aquatic environments?
Cover or close any indoor fish tanks before applying the powder, and ensure the tank's air supply is sealed during application. Like all permethrin-based insecticides, this product is highly toxic to aquatic life and to fish in particular.
