Wasp / Hornets Nest Treatment

 

Wasp stings - protecting you and your family

Take care when dealing with wasps and hornets (a larger member of the wasp family). Hornet and wasp stings are potent and can attack in large numbers if disturbed. Being stung by a common or social wasp (also known as a yellow jacket) is a painful experience and can be life threatening to those who are allergic to wasp stings and may suffer anaphylactic shock. It is possible to reduce the risk of being stung by taking sensible precautions and ensuring that a wasp or hornets nest is properly treated or removed.

If you have been stung by a hornet or wasp, please refer to our guide to treating insect stings. This also has advice about how to avoid being stung when outdoors.

Identifying Wasps

The bright yellow and black striping of wasps is a warning pattern that has been mimicked by many insects to take advantage of the deterrent effect of appearing wasp like. These harmless mimics include hover-flies, day moths (such as the Ash Borer) and beetles that visit flowers to feed on pollen and nectar. The insects most often encountered in Uganda are the Common or Social Wasp. Only female wasps have the long distinctive stinger, which they can use repeatedly (unlike bees).

Wasp Nest

Take great care when dealing with wasps as they have a potent sting and can attack in large numbers if disturbed or threatened. A wasp or hornet trapped indoors can be dealt with using a wasp and fly killer spray.

If you are experiencing high numbers of wasps or hornets in your home or garden it is likely that there is a wasp or hornets nest nearby. When queen wasps come out of hibernation they search for sheltered places with easy access to the outdoors to build their nests, often in domestic housing, making use of attics, wall cavities, roof spaces or under the attics of buildings. A single nest may contain thousands of insects which can attack if disturbed or provoked. If the location of a wasp nest is likely to put people at risk, then it should be treated immediately.

Wasp nests are made from chewed wood pulp and saliva, giving them distinctive papery walls. A queen will start to build in the spring, beginning with a nest about the size of a walnut but as the first batch of workers hatch to take over nest building, the size of the nest increases rapidly. By summer, a mature wasp nest can contain between 4,000 - 6,000 individual insects and typically can be 30cm in width. Other sites can include lofts, garden sheds, trees, thick hedges, bird boxes, garages and out-buildings.

The risk from wasp stings are particularly high towards the end of summer. It is therefore preferable to treat a wasp nest earlier in the year before wasps become more aggressive.

How to Get Rid of Wasps and a Wasp / Hornets Nest

To locate the wasp nest, watch the flight path of returning wasps. If the nest is the near the home, keep nearby windows closed. If you suspect the  nest is in the loft, take great care in opening and entering the loft space.

Do not attempt DIY wasp nest removal if:

  • You suspect you are sensitive to wasp stings,
  • If the wasp nest is indoors or is difficult to access.
  • Never attempt to treat a nest when on a ladder or from a raised height.

Whilst DIY products may be effective against smaller problems, we would recommend you seek professional treatment for large wasp problems.

Wasp swarms are dangerous - if in doubt, seek professional help to get rid of wasps. Rentokil does not offer a nationwide service to get rid of wasps, but your local Yellow Pages will be able to provide you with details of an operator who specialises in wasp control and removal.
