Adders
At this time of year, we thought it would be useful to provide some information on Adders which have been seen in Foxhill historically. It is also particularly important for those who walk dogs in the area as they may be bitten to.
Adder snakes are venomous but generally not highly dangerous to healthy adults; bites are painful and can cause swelling, but fatalities are extremely rare.
Risk and Behaviour
Adders are shy, non-aggressive snakes that usually bite only when provoked, stepped on, or handled. They prefer to flee or hide rather than confront humans, making bites uncommon. In the UK, around 50–100 human bites are reported annually, with an additional 100 bites to dogs, and fatalities are exceptionally rare, with only 55 deaths recorded over the past three centuries. Most bites occur between April and September, peaking in July and August.
Venom and Symptoms
Adder venom is primarily hemotoxic, affecting blood and tissue. Immediate symptoms include sharp pain at the bite site, swelling, bruising, and sometimes redness. Systemic effects can develop within hours, such as nausea, vomiting, dizziness, and occasionally a metallic taste in the mouth. Severe complications, though rare, may include tissue necrosis, hypovolemic shock, or anaphylaxis. Children, the elderly, and individuals with pre-existing health conditions are at higher risk of serious effects
Medical Treatment
All adder bites should be treated as a medical emergency. Prompt hospital care is essential to monitor symptoms and prevent complications. Treatment may involve symptom management, immobilization of the affected limb, and in severe cases, administration of antivenom. Even with treatment, severe bites can result in long-term tissue damage or scarring.
Safety Tips
- Avoid handling or approaching adders.
- Watch your step in areas where adders are known to live.
- Wear protective footwear when walking in tall grass or heathland.
- If bitten, remain calm, immobilize the limb, and seek immediate medical attention.
In summary, while adder bites can be painful and occasionally serious, they are rarely fatal, and with prompt medical care, most people recover fully. Awareness and caution significantly reduce the risk of being bitten.
