Why do they bite? What causes our skin to react to it?Is there a chemical they inject in us?

Either as a defense (ants & spiders) or because they're hungry (mosquitos).
Depends on the insect ants=formic acid, spiders=neurotoxins, necrotizing factors, etc....Usually the bump you see is a result of histamines being released at the site of the bite. It's the histamines and other chemicals in your skin that are responsible for the swelling, redness, and warm sensation. It's a natural response to any kind of invasion whether it's poison from a bite or an infection.

Some bite as a instinctive response to threat. Some bite because they are using you as an available source of protein.

Ants usually bite in response to perceived threats and that response in mediated/initiated by pheromones released in mass. Many ants sting and the venom injected is formic acid.
