What are suggested control methods for wasps?
A. Knockdown insecticidal aerosol spray i.e. ‘Flying Insect Killer’ can be used to treat occasional wasps that become a problem when they appear indoors. Only a product suitable for use indoors should be used. Wasps nests that are not causing a problem can be left alone. You can dispose of any old nests at the end of the following year. You may encounter queens that have chosen to hibernate in the nest for the winter period if you move it too soon. Old nests will not cause any damage if left in place. For nests at ground level an insecticidal dust can be applied around the entrance of the nest. Nests that are built in lofts or under eaves are more difficult to treat yourself and are best treated from the outside. If the nest is treated from inside the loft you may not be able to get at the nest entrance to treat it effectively and if you disturb the nest during treatment you may encounter a swarm of angry wasps trying to protect their nest.
