Hornet Nest Treatment Plan
How Do I Know I Have A Hornets Nest?
If you see hornets entering & leaving a hole in the ground, a wall, roof or any other part of a building between May & November then you probably have a hornets nest. As the numbers in a nest are not as great as wasp nests they are often not noticed until much later in the year, often when the days are shortening as hornets are attracted to artificial lights.
You may be getting ‘unexplained’ hornets inside a room which may indicate a nest nearby.
Do not be tempted to block the hole up, this will make them angry and aggressive but will not kill the nest, they will find another entrance & may even come inside the house.
Nests are a grey or brown structure made of a paper mache type material. Hornets are aggressive and will sting readily if they think the nest is in danger but generally they are less aggressive than wasps.
Why Should A Hornets Nest Be Treated?
If you don’t treat a hornets nest it will eventually die out but before this happens the nest will produce fertile Queens that will hibernate and start nests the following year. The lifecycle of hornets is very similar to wasps. They feed on the same foods and change habits with the seasons. In the Autumn they change their diet and as wasps can cause massive amount of damage to fruits in the Autumn.
Hornet Nest Treatment
We treat the nest or the entrance of the nest using an insecticide called ‘FICAM D* which contains the chemical Bendiocarb 1% w/w. This is a modern biodegradable insecticide that is not highly toxic to mammals, but is extremely so to the hymenopterous group of insects (Hornets, Wasps, Bees and Ants). The entrance to the nest or the nest itself will be treated using this insecticide.
What Do I Need To Do Afterwards?
After treatment the nest will remain in a hyperactive state for up to 3 hrs, but usually Hornet activity ceases much sooner. Keep people & pets away from the area until activity has ceased. Close windows & warn neighbours to keep away.
The 3 main points to remember are:
- A treated nest cannot ever be reused.
- A Hornet nest cannot move its location, once started it is there for the duration of its life (7-8 months), nor can Hornets move from one nest to another.
- All nests start in the Spring, never later than May but the expanding populations are not often noticed until much later in the year. The population expands from 1, when the nest starts up in the Spring, to around 700 in the Autumn but usually much less than this.
The nest itself is made of a substance similar to paper mache, which will not rot or smell, so it is quite safe and hygienic to leave where it is. If the nest is accessible and you do decide to remove it, wait for at least four weeks as this will ensure that no one will get stung by any larvae that have hatched out after the queen has died, occasionally scratching may be heard from the nest during this period but as long as outside activity has ceased, don’t worry as this will soon die out. If the nest is treated in the Autumn dying Hornets, Queens and Drones may still appear for up to 20 days after treatment. Never block the entrance to a nest unless you are quite sure the nest is dead e.g. Hornets are not flying in and out of the entrance.
Hornet Nest Removal
It seems to be common sense to remove the hornet nest after treatment but the removal of a hornet nest is not necessary. Firstly if a nest was removed as soon as the treatment was carried out then the hornets that were out foraging would return, find no nest & attempt to rebuild the hornets nest. When they return & find a treated nest they either get contaminated by the insecticide or exhaust themselves by flying around the nest in a state of panic. They only attempt to rebuild the nest if it isn’t there. Secondly a hornets nest can never be re used. So if you want to remove the hornets nest then we recommend you wait at least 4 weeks before doing so. In a lot of cases the hornet nest is not accessible. The nest may be in a cavity wall or a soffit that cannot be seen.
