Wasps at your property?

If you encounter the odd wasp in the house, its often nothing to worry about. However, if you are noticing wasps becoming more frequent, often following the same flight path, then that is a warning sign that there may be a nest nearby.


Wasps are conspicuous buzzing insects with yellow and black striped, wasp-waisted bodies, 10-15mm long. They have a sweet tooth at one end and a painful sting at the other.

The queen wasp is larger (20mm) and she hibernates overwinter, making a nest in the spring in which to lay her eggs. She feeds the grubs on insects until they develop into worker wasps, three to four week slater. Workers, all sterile females, forage for over a mile in search of food. One nest may produce 30,000 wasps in a year.

At their peak in August and September with the youngsters reared, the workers turn to the sweet food they prefer and become a nuisance wherever this is available. If annoyed or threatened, wasps will sting and the best remedy is to apply an anti-histamine.

REMEDY: Close or screen windows with a fly screen if wasps are a major problem. Individual wasps can be killed with a fly killer aerosol. The old fashioned jar, one third full of jam and water, covered by a punctured paper lid will trap and drown them.

If you find a wasps’ nest in a wall or bank, apply one of the range of domestic products available labelled for wasp nest control. Nests in roofs or sheds need to be thoroughly sprayed with insecticide. This can be hazardous and is best performed by professional technicians. Some BPCA pest control contractors will do this, as will local authority environmental health departments.

Commercial premises can be protected by insect screening of windows and the installation of electrical devices which attract, kill and catch the bodies.

Good to know…

Bees are often confused with wasps because they have a similar shape. However, wasps have distinct yellow/black bands around the abdomen whereas bees have a more non-descript light brown/brown-yellow colour. Bees tend to be 'hairy' to allow pollen to be gathered more easily whilst wasps tend to be bald and shiny in appearance. Also, only Bees swarm but Wasps don’t swarm. Bees are more likely to be active in the springtime and remain active throughout the summer and into the fall. Wasp’s season is normally April until about October time (dependant on weather conditions).

Graham Pest Control do not treat for bees. We would recommend contacting a local beekeeper in your area or please find attached a link to the Scottish beekeeper's association who should be able to assist with them  Bee Gone – may be able to assist with removing honeybees if a beekeeper can’t help. If they are bumble bees a beekeeper will not remove them but if you visit the following websites for Bumblebee Conservation Trust -  they can provide you with assistance.
