Please be careful adders may bite. Adders are normally shy retiring creatures that will usually run away and avoid conflict. However particularly early in the morning during the summer they will come out into the open and bask and may be sluggish and a bit tetchy. They will only bite if handled, trodden on or otherwise molested. They are slightly venomous and people who have been bitten normally describe it as a painful bee sting. On very rare occasions the bite can be fatal so if you are bitten prompt medical attention is a sensible approach. Adders are rare; please treat them with care.
