Wasp nest removal.

Should a wasp nest be removed after treatment?

If a wasp nest is treated using Ficam D, after the wasps have died, the dust remains in the nest but has quite a long shelf life which will sit there waiting for its next victim. Very often after a nest has been treated, other wasps from nearby nests will attempt to raid the treated nest as it is now un-defended. As these “scavenging” wasps enter the nest, they too get the dust on them and die, so now the treated nest is actually killing wasps from another nest.
Also if the nest is left in place, in the spring when queen wasps which are emerging from their winter hibernation start exploring potential nesting sites and encounter the treated nest, there is a good chance that they will investigate the treated nest and succumb to the dust, and therefore will die before ever having the chance to build a new nest.
We advise that wasp nest removal should only take place when the nest is posing a problem or is in the way. The vast majority of wasp nests can be treated and left where they are.

How long does it take to remove a wasp nest?

If your wasp nest needs to be removed for whatever reason, if possible it is better to have the wasp nest treated then after all the foraging wasps have returned to the nest and succumbed to the insecticide, wasp nest removal can be undertaken. The removal of the wasp nest will not be on the same day as treatment and sometimes pest controllers will charge an extra fee for returning and removing a nest. If a nest is treated with a quick knock down treatment (wasp nest foam treatment) and removed straight away, the wasps that are out foraging when the nest is treated will not have been killed and will return to the location of the nest. It has been known for wasps to start rebuilding a nest from scratch after the original nest was treated and removed using quick treatment methods.
If you think you need to have your nest removed, discuss this with your local wasp controller to find out the best solution.

If a wasp nest has been treated with Ficam D and you want to remove the nest, we advise that you leave the nest for at least 24 hours before attempting to remove the nest from its location. This is to ensure your safety and to prevent you coming into contact with any live wasps that may still not have been treated as some foraging wasps do not make it back to the nest each day and occasionally one or two wasps will arrive the day after treatment. It is inevitable that some foraging wasps will spend nights locked in sheds or houses after a day’s hunting for food.
