Beware summer bloodsuckers
WITH the sun out and temperatures soaring to more than 30C in parts of Wales, it’s no surprise that people are taking the opportunity to spend a few hours working on their tans in the garden or enjoying a day out at the beach.
But the problem with that, for some, might be the possibility of getting bitten by some form of insect.
Bees, wasps, midges – we’re seeing plenty of those around at the moment and they can make it tricky just to sit outside, never mind dining al fresco or having a barbecue.
And one insect you don’t want to get bitten by is the horsefly.
The Northumberland Wildlife Trust says you’ll find horseflies between May and September, which means we’re right at the peak of horsefly season.
What are horseflies and where do you find them?
Horseflies, also commonly known as clegs, have razor-sharp jaws and can inflict a very painful bite.
They are large, dark-coloured flies measuring 1-2.5cm. As their name suggests, they like to feed off horses, so you’ll find clusters of them near stables and grazing fields. Cows are another favourite source of blood for horseflies, although any large mammal will do – including humans and dogs.
You’ll also find horseflies around pools, woodlands, meadows and grassy fields. Anywhere it’s nice to spend a sunny day, really.
Why do they bite?
The female flies need to feed off blood so they can produce eggs. Their jagged teeth slice open skin, while the flies also release an anticoagulant to stop the blood from clotting while they eat.
The male flies feed off nectar.
How do I know If I’ve been bitten by a horsefly?
According to NHS Choices, a bite from a horsefly can be very painful and the bitten area of skin will usually be red and raised.
You may also experience:
■ A larger red, raised rash (called hives or urticaria);
■ Dizziness;
■ Weakness;
■ Wheezing;
■ Part of your body becoming puffy and swollen.
Horsefly bites can take a while to heal and can become infected. This is because, unlike midge bites, they cut into the skin rather than pierce it, which can cause the wound to become infected.
What should I do if I get bitten?
Keep the wound clean with antiseptic soap and warm water to avoid it becoming infected. Other than that, you won’t usually have to do anything.
However, if you do show symptoms of an infection, such as such as pus or increasing pain, redness and swelling, then contact your GP.
In rare cases, some people suffer allergic reactions. Symptoms include dizziness, wheezing, difficulty breathing, a blotchy skin rash and severe swelling that may be visible on your lips or tongue. If this happens to you, seek immediate medical help.
And avoid scratching the bite. It won’t stop the itching and can increase the likelihood of an infection.
