Insect bites and stings can be common, particularly in spring and summer, and usually cause only minor irritation. In rare cases, people can have a serious allergic reaction to a bite or sting that requires immediate medical treatment - if this is the case then a leader will refer directly to the Emergency & Serious Incident Procedure. If there is prior knowledge to suggest that a child will have an allergic reaction if bitten, then Saplings must be informed before any activities take place on site. Children with EpiPens ideally will have one that can stay at Saplings. Teachers carry all medications that may be needed on trail in their first aid backpacks.
