How long will Decathlon keep killing insects?
Since OHP Decathlon 20 WP contains Cyfluthrin, you should get residual control for at least 30 days for listed uses. The product label does allow you to retreat for active pest infestations as needed, but you should be cautious of possible phytotoxicity if the product is applied too heavily to sensitive plants.
