Here are some natural home remedies that could come in handy during such situations:
Wash the bite area thoroughly with soap and water.
Rub the affected area with the inside of a banana peel. It is said to provide amazing results in reducing irritation and swelling.
Apply raw honey immediately after being stung by an insect, as this helps in keeping away any pain.
Apply Tea tree oil, as the antiseptic compounds present in it, make it a powerful disinfectant.
Cut an onion and rub it on the sting, as this helps remove poison, if any.
Mix a tsp of lavender essential oil with a tablespoon of vegetable oil, and directly apply on the injury. Lavender helps reduce swelling and stops itching.
Mix a tbsp. of Echinacea root tincture with one tablespoon of distilled water and 1/8 tsp. of lavender essential oil. Add the liquid slowly to a tbsp. of bentonite clay while stirring continuously. The resulting paste can be applied to the injured area. This herbal poultice can be stored in an air-tight container. In case it gets dried out, add water, until it is moist enough to stick to the skin.
A tea made out of fresh or dried lavender flowers can be used as a skin wash to relieve itching caused due to flea bites.
In cases of bites by venomous insects, or a wasp or hornet sting, Basil can be applied, as it speedily draws poison.
Another herbal remedy recommended by most herbalists is a combination of tea tree oil, peppermint and lavender. These help in neutralizing toxicity. They can help stop itching almost immediately and can reduce skin inflammation. This mixture can be added to honey or baking soda, and apply a drop or two onto the insect bite.
