There are some other things you can do to reduce your exposure to insects this spring and summer: Stay calm in the presence of bees, wasps and hornets and move away slowly – do not wave your arms to ward them off. Insects tend to be more active at sunrise and sunset, so you could cover your skin with sleeves and trousers during these periods. Cover food and drink outdoors (especially sweet food) and be extra careful around rubbish, compost, plants and stagnant water. Try not to camp close to water and this is a haven for horse flies and mosquitos. Use thin netting or door beads to deter insects or close doors and windows.
