Dust applications against cockroaches

Casey Prewitt, Sales Manager, Professional Pest Management, Neogen

Cockroach services have changed quite a bit over the years, and one area that seems to be overlooked by many is that of dust applications. Perhaps it was the stigma of customers incorrectly overapplying dust in every nook and cranny of their homes. Or perhaps changes in the current products offered on the market affected the popularity of dusts. Either way, when applied according to the label, dust formulations are a great component of an integrated pest management program because they can provide lower cost applications, with low to no odor. When undisturbed in cracks and wall voids, these applications can provide a long residual life. Dusts also offer an ideal opportunity to reach cockroaches in deep harborage; the insects can encounter the treatment long after it has been carried out.

For best results, apply dust lightly to take advantage of air flow carrying the product throughout the voids. Making sure the dust applicator is no more than half-full will allow air movement to transport dust particles into further recesses.

One last tip: Always have a damp cloth at the ready, to eliminate any excess dust that may appear outside of the void.
