Heavy rainfall mixed with a rise in temperatures in spring allow insects such as mosquitoes, midges and gnats to flourish.
The UK is home to more than 30 types of native mosquito species, some of which bite and cause a nuisance.
The most common indoor species of mosquito is called the 'culex pipiens'. It doesn't bite, but it looks very similar to other species that do bite.
What's the difference between mosquitoes and midges?
Midges are sometimes confused with mosquitoes. Midges are related to mosquitoes and also appear in massive numbers on buildings.
Mosquitoes tend to bite and feed on blood, which most midges don't do. However, there are some midges that do bite.
The main difference between a mosquito and a midge is that mosquitoes have scales on their bodies and wings.
Are mosquito bites dangerous?
Mosquito bites often cause small red lumps on your skin. These are usually very itchy.
Mosquitoes don't cause major harm in the UK. However, in some parts of the world, they can spread serious diseases such as malaria.
Fully formed female mosquitoes feed on the blood of birds and mammals, including humans, to feed their developing eggs.
Male mosquitoes live on plant nectar and fruit juice.
How can I prevent Mosquitoes from biting me?
To prevent mosquitoes from biting you:
- Cover exposed skin. If you're outside when insects are particularly active, such as at sunrise or sunset, cover your skin by wearing long sleeves and trousers.
- Wear shoes when outdoors.
- Apply insect repellent to exposed skin. Repellents that contain 50 per cent DEET (diethyltoluamide) are the most effective.
How to control or treat Mosquitoes
You can spot mosquito eggs in standing water such as ponds, garden pots or sometimes even pet water bowls.
The black eggs are laid in batches that look like small, black pumpkin seeds floating at the edge of the water.
You can remove unwanted eggs by draining the water. You can prevent eggs by making sure any water butts have lids.
