Fast Knockdown Insect Control Powders

“Fast knockdown” powders are designed to deliver quick control when insects come into direct contact with the powder. They’re best used when you’ve found active insects or a clear hotspot, and you want faster results than a long-term monitoring approach.

It depends on your goal:

• For fast knockdown: apply a light dusting exactly where you’re seeing activity (e.g. along a trail, around an active crack/gap, or where insects are emerging).
• For hidden activity: dust into cracks, crevices and voids where insects travel and hide — skirting gaps, under sinks (around pipework), behind kickboards, and around entry points.

Avoid over-applying: a thin, barely visible layer is usually more effective than piles (insects are more likely to walk through it).

Sometimes—but not always. “Fast knockdown” refers to quick results on contact, while longer-term control depends on whether the powder is designed to stay active as a residual treatment. If activity keeps returning, consider combining:

• Fast knockdown for what you can see now, plus
• A residual treatment for pathways/harbourages, and (where suitable) an IGR to help break the life cycle.
