It is an immediate-kill product. There is a short residual effect that will kill all insects in the nest within 48 hours.

It kills wasps and hornets immediately.

Yes, with its fast- killing action. It is best to spray either early in the morning or late in the day, when most of the wasps and hornets are nestled in for the night. After 48 hours, it is safe to remove the nest, as wasps and hornets that were out of the nest at spraying time will not re-enter. They will move on.

The WASP OUT Wasp & Hornet Killer can be used on nests from up to 6 metres (20 ft) away - no ladder required and because of the distance, less chance of getting stung. WASP OUT Jet Foam Wasp & Hornet Killer is also used on nests but from a shorter distance of 2-3 metres (6-8 feet). The foam acts as a physical barrier, completely engulfing the nest and cuts off any wasps trying to escape. The long straw inserted into the nest allows for the foam to completely fill and saturate the nest.
