Horsefly Bites
Horsefly Bites
Horsefly bites are rising fast in the UK as a heatwave sparks an invasion of the painful biting insects. Soaring temperatures are bringing an influx of the bugs similar to those found in Mediterranean countries.
The flies are known for targeting horses but can often be found around ponds, pools, woodlands, grass, livestock and humans. Horseflies like warm weather and normally appear in June and July so they tends to bite on warm, sunny days, especially your head and upper body. Insect repellents will help keep the horseflies at bay and it’s a good idea to protect yourself if you’re going into rural areas.
Light coloured clothing will also make you less of a target for the flies, which are attracted to dark, moving objects. The flies don’t normally head into dark areas – so you will be better protected in the shade.
In general these bites will clear up within a few hours or days and can be safely treated at home. However, although the horsefly doesn’t spread disease, its bite cuts the skin rather than piercing it and as a result it can cause extreme pain, leaving large swollen sores full of pus on the skin and develop into large, red, itchy, swollen bumps within minutes. Victims may also experience dizziness, weakness and wheezing.
