There are 2 main types of wasps in the UK, solitary and social, however it is the social wasp that tends to cluster in the summertime.
A typical nest population is around 5 to 10 thousand. These nests can be found in various locations, such as, attics, walls, roof spaces and eaves of houses, as well as in trees, hedges and underground. The nests are built from items such as paper, cardboard and scrapings of wood which is mixed with their saliva to form cellulose.
Nests are only used once and they will be abandoned once the spring/summer cycle is complete and can be safely removed by knocking the nest down using a broom handle, however, for those that need to remove a nest before this time, here are a few tips on how to do so.
- Protective clothing. Cover your body and face as much as possible. Wear long sleeves, long trousers and eye protection is a must.
- Pesticides. If you are using chemicals, read the instructions properly as some pesticides are harmful to humans, pets and wildlife if used incorrectly. Use a good quality insecticide that is fit for the purpose; using the wrong insecticide will mean you end up facing several thousands of angry wasps and not destroying the nest at all.
- First Aid. Make sure you have the correct first aid for any wasp stings as these are painful and can be very severe and dangerous to some people, unlike the bee, they can sting multiple times and WILL attack you if you get too close.
Destroying the wasp nest
- The eaves of the house are the most common place for wasp nests and they do cause problems. It is easier and better to treat the nest from inside the roof space itself. This is not easy and the wasps will fly towards light, so where possible keep the lights off. Using a torch to locate the nest (remember not to shine this directly onto the nest) and providing the nest isn’t too far down the eaves, use a powder insecticide. If this is a bit too tricky, do not risk being stung and contact a pest control company to do this for you.
- Nests in air bricks are also common and are easy to destroy. The nest itself may be 6 feet inside the cavity. Use a powdered insecticide and spray the area a few times for it to take full affect. The powder around the air brick entrance holes will mean that the wasps will carry the poison into the nest. The best time to spray the area is during the day, but many people prefer to spray at night as there are fewer wasps around. Make sure you spray all the holes as the wasps are clever enough to use the holes that don’t have the insecticide spray in them.
- Nests in roof voids or high up places are best left to the pest control expert as the difficulty in access means that specialist equipment is needed, including a full protective wasp suit.
- A wasp nest in a bush or shrub requires you to stand about 15 feet from the nest with a powder insecticide. Using a good quality powder insecticide, make sure you give the nest a ‘good dusting’ especially around the exit path of the wasps.
- Wasp nests on the ground are easier to deal with; simply ‘puff’ the powder insecticide into the tunnel and leave. No special equipment is needed.
If you are at all unsure, it is best to avoid injury and use a professional pest control company.
