What makes fleas bite so hard?

Answer 1

This is a peculiar question. All flea bites have the same force and they are generally on animals not Humans though they can jump from pet to owner but they will not survive. Flea's like ticks and mosquitoes drink blood but only the females. Flea's need animal blood to survive mostly found on dogs, cats, and wild animals.  Mosquitoes need human blood but are not limited to just humans they prefer the sugar in our blood.  Ticks nasty little things,not only do they need blood but they like to burrow under the skin causing pain to the host and difficulty in removing them. In case you ever wondered what the purpose of these parasitic creatures is , it's to feed fish and other insect eaters, though i do think nature could have givin us something not so annoying to feed the insect eaters.

Answer 2

they want ur blood
