Are Wasps Dangerous? Understanding Stings and Nest Disturbance in St Mary Hoo
A nest in the ground gives no warning until someone treads on it or runs a machine over it, so knowing the signs outdoors is a good protection.
The nest you cannot see
Most people picture a wasp nest as a grey paper ball hanging in a tree, but many are underground. A wasp may take over a hole left by a small animal, a gap under a path or a crack beside a fence post, and build below the surface. The only sign is a small round entrance, sometimes no wider than a coin, hidden in grass or leaf litter.
That is why ground nests are some of the more hazardous ones for people outdoors. Someone walking through rough grass, a child chasing a ball or a dog running ahead of its owner can step on or beside an entrance before noticing a thing. The first indication is often wasps pouring up from the ground and stinging legs and ankles, which are the nearest targets.
Nests begin from late April depending on the weather, so a hole that is only a few wasps wide in spring can become a large colony by late summer. The entrance often stays small even when the nest below is very big, which is why the size of the hole tells you little.
How to recognise an entrance
You do not need to find the hole to know it is there. Look for patterns:
- Wasps flying low to the ground and disappearing into the same spot repeatedly.
- A small bare patch or hole in a lawn, bank, verge or path edge, with some loose soil around it.
- A steady stream in and out, particularly on warm, still afternoons.
- A faint buzzing that seems to come from beneath you.
On the Hoo Peninsula and in any open or rural setting, the same caution applies when walking off the path. In St Mary Hoo and nearby, rough ground, field edges and the sides of tracks are places where animals dig and wasps may follow. Keep to clear routes when you can, and watch the ground a few metres ahead.
If you are walking with others, agree a simple plan. The person at the front watches the ground, and anyone who sees wasps going into the soil calls out and the group turns away, without pausing to look.
If you have trodden on or near a nest
Get away at once. Do not stop to find out how many wasps there are, do not swat, and do not try to look back at the hole. Move briskly but steadily away from the spot, ideally in a straight line, and carry on for several metres, then check yourself for wasps on clothing and in hair. If you have children or a dog with you, call them away and carry the smallest.
Once you are clear, deal with stings in the usual way. Wash, cool and watch. Call 999 if there is swelling of the face, lips or throat, a wheeze or trouble breathing, dizziness or a widespread rash. A large number of stings needs medical attention even if there are no allergy signs.
Remove any wasps clinging to clothes by brushing them off with a firm sweep away from your body once you are clear of the nest, not before. If one is on your face, move slowly and step out of the area before you try to deal with it.
Dogs and children on the ground
Dogs often find the nest first because they follow scent. A dog that sniffs a hole and gets stung may run back to its owner with wasps following. If your dog cries out and bolts, walk away from the area and keep the dog close. Seek veterinary advice if it was stung on the face or mouth.
Children are low to the ground, so they are in reach of the wasps' first response. Teach them that holes in the ground with insects flying in and out are not for exploring. Avoid letting them play in uncut grass or on banks where you have seen activity, and keep them in clear, mown areas until it has been dealt with.
Horses and other animals that graze or are ridden through rough ground can also be affected. If you look after animals, walk the paddock edges in warm weather, and move stock away from an entrance if you find one.
What not to do about a ground nest
There are a number of old tips about pouring things down holes or covering them over. Do not try any of them. Wasps will come out of an entrance that you block, and they may find other ways up to the surface that you cannot see. Disturbing the soil, digging or driving machinery nearby can also spark an attack.
Mark the location with a stick or cane from a distance, ideally in the evening or early morning when fewer wasps are flying, and leave it alone. If a gate, path or play area is nearby, keep people out of the zone.
Do not try to burn out a nest or pour boiling water on it. Both are likely to injure you and leave the colony angry. Leave it to someone trained and insured.
