Wasps usually make nests in air vents, lofts, roofs, under guttering in the eaves and under flat roofs. If you see wasps going in and out of a particular hole on a regular basis it is likely you have a wasps nest. As a general rule, you should not attempt to treat wasp’s nests by yourself as it is likely to be difficult and potentially dangerous. On no account should you remove a nest from the roof space, this should be carried out by a professional pest controller. If you have a problem with a wasps nest you should contact 24 Hour Pest Control.
