Thousands of spider species exist, but only a few can bite through human skin. However, if you are bitten by a spider, you may notice small puncture marks that can be red, swollen and painful.
The most serious bites can turn a dark red, blue, or black, dry out, and form a sore. This sore often heals after a few weeks, but can last for months

Spider bites can cause a small, red, raised bump on the skin, which may itch or burn.
Different bug bites can leave a bruise. These include:
When a mosquito bites a person, it injects its saliva into the person’s blood. Your body recognises the substances in the saliva as foreign and launches an immune response to fight the foreign substance.
A substance called histamine is released by the body as part of this immune response and this causes the bite to itch.
You can treat an insect bite or sting at home by:
Avoid using vinegar, bicarbonate of soda, and other home remedies you may have heard about. Many of these remedies are not recognised treatments and are unlikely to help with insect bites.
If you have been bitten by a mosquito, regularly applying a cold compress (such as a flannel or cloth cooled with cold water) or ice pack to the bite may help to relieve any swelling.
Speak to your pharmacist about antihistamine tablets and other non-prescription medicines that may help to improve swelling.
