Bees and wasps

Bees, wasps and ants are all insects from the order Hymenoptera. Those of this order which cause mortality or morbidity include the honey bee (Apis mellifera), the European Wasp (Vespula germanica), native wasps (Polistessp.) and ants from the genus Myrmecia. Most often their sting causes a painful local reaction with little systemic effect. However in sensitized individuals these stings can cause severe local and/or generalized allergic reactions, including anaphylaxis.

Note Dose-dependent toxicity can sometimes be significant with multiple bee and European wasp stings. Haemolysis, rhabdomyolysis and metabolic derangement may precede clinical deterioration.

Prevention of bee and wasp stings (adapted from "Living with European wasps", Victorian Department of Natural Resources and the Environment):

• Beware of clovered lawns as bees are usually attracted to this pollen.
• Try to avoid wearing perfumes, cosmetics and bright clothes, particularly on sunny days when bees and wasps are most active.
• As a precaution, shoes should be worn around gardens and lawns, particularly when watering.
• Do not disturb wasp nests or bee hives unless fully protected, and never approach them during daylight hours, as this is when they are most active.
• Beverages, particularly sugary ones, attract bees and wasps - use glasses or straws rather than drinking from cans or bottles whilst outdoors.
• Before consuming food outdoors check for wasps. Wasps like to hide inside and underneath food - particularly meat, fish and confectionery.
• Do not swat at or annoy wasps that are hovering around food - wasps are attracted to moving targets.
• Warn children of the dangers of wasps and bees - particularly about the dangers of approaching nests.
• Have wasp nests destroyed if found.

The order Hymenoptera is a large insect order which contains two suborders: Apocrita (ants, bees and wasps) and Symphyta (sawflies). Each suborder comprises of numerous families and species.
