How to Use

Home Defense is a ready-to-use product - no dilution or mixing is needed. Simply attach the sprayer and you're ready to go.

Shake the container well before use

Connect sprayer as instructed on the back label of the container

Apply a thorough spray holding the nozzle 20-25cm from surfaces being treated

Spray evenly and to near the point of runoff - 3L should cover around 60m2

Exterior home protection

Apply in a band 2-3 metres wide on to soil or other surfaces around and directly adjacent to the house. If the treated band is disturbed or is exposed to rain, the product will need to be re-applied to maintain the barrier

Spray under the eaves, around window frames, behind down pipes and guttering and around outbuilding close to the house. Areas exposed to rain should be re-treated to maintain protection.

Spray in and around the letterbox

For houses built above ground level, spray under the house around stumps, floor joists and the underside of floorboards


Ensure rooms being treated are well ventilated and remove any pets. Apply around the perimeter of each room paying attention to likely entry points.

Spray under cupboards, ovens and cooktops, under and behind refrigerators, etc - all potential hiding spots for insects and spiders.

Don't forget the roof cavity and around air vents, heating/cooling outlets and ducted vacuum points.

Wait until the spray has completely dried before allowing pets or children back into treated areas.

When to Use

Any time insect pests and spiders are present in and around the home.

Safety Information

Safety first: 

Read the instructions on the product packaging before use and take particular note of any warnings or cautions on the label


Technical Details

Home Defense contains 0.5g/L bifenthrin, a new technology insecticide that is not a scheduled poison and is of very low toxicity to humans, animals and birds

The chemical in Home Defense, bifenthrin, works in two ways: by killing when sprayed directly on to insects and spiders (contact killing) & by direct contact with the chemical when it is sprayed on to surfaces around the home that insects and spiders may travel across (residual effect)

Residual control on non-porous surfaces (timber, fibre cement, ceramic, glass, aluminium, painted surfaces) may last for up to 9 months provided the surface is not exposed to weather or other factors that may disturb it.

On porous surfaces (bricks and concrete, for example) residual effect will be significantly shorter.
