Why don't we feel the pain at the time a mosquito is biting us?

Question

we feel the pain after biting.why so?

Answer 1

Often it depends on the species of mosquito doing the biting. There are species that are adapted for feeding on large mammals, and carefully target their bites, accompanied with mild anesthetics so that we don't even notice the bite as it occurs.

Other species are less careful, and their bite is quite painful. Some of them are adapted for feeding on other hosts, and when they bite a human it's more or less a mistake. These individual mosquitoes often get squished, but there's usually lots more out there where that one came from.

Some of them have a quite painful bite, but rely on getting lots of biting quickly, and drawing their blood meal very quickly. We can only swat so many of the little so-and-sos, and as long as some of them survive to take blood away, the species prospers. The salt-marsh mosquito (Stegomyia albopicta) has a notoriously painful bite.

The pain and itching after the bite is usually the body's reaction to the anti-coagulant the mosquito injected while feeding to get the blood flowing quickly. Some people react more to the substance than others.

Answer 2

Some people dont feel it because mosquitos are sneaky and....

Excerpt from Wikipedia... As opposed to a syringe's typically smooth needle, the mosquito proboscis is highly serrated, which leaves a minimal number of points of contact with the skin being pierced — this reduces nerve stimulation to the point where the "bite" is not felt at all, which is generally the case

However I almost always feel when they bite unless I am really occupied doing something else. Most of the time I feel it right away it feels like a picky itch when they first start to bite you. Sometimes you feel it sometimes you don't, until later when it gets itchy..LOL

Answer 3

Mosquito injects a analgesic/ anaesthetic compound first before sucking the blood, this analgesic compound also works like a asprin by diluting the blood. Also the compound has anti clotting chemicals.

If a person is injected with local anaesthetic and operated, he will start feeling the pain as anaesthetic compoud starts to fade. Same thing happens here too.

One information for you MAN IS A obtuse ANIMAL WHO HAS NO BRAIN ON HIS OWN, HE TAKES EVERYTHING FROM NATURE!

Answer 4

A mosquito actually has pain killers when it sucks your blood so you dont even know it is biting you. afterwards after the pain killer dies off, you start to feel the pain and the itch.

Answer 5

weird and wonderful because it sounds the reason you sense the alleviation has to do with how sensations are transmitted from nerve endings on your techniques. It seems that transmission isn't by potential of electric value, it truly is a chemical chain reaction from one nerve cellular to the subsequent. for this reason your discomfort reflexes are quite sluggish. electrical energy travels on the brink of velocity of light. Chemical chain reactions are plenty slower. back to the alleviation question. the non-provide up firing of all the nerves contained in the chemical reaction certainly exhausts the nerve cells, requiring a protracted era to recharge. once you scratch, you're firing those nerve cells and overloading the circuit. the alleviation comes because of the fact the recharge era interprets right into a sensation of no discomfort. as quickly as the nerves recharge, the itch sensation returns.

Answer 6

Same reason you don't feel an injection, the needle is so fine and sharp you don't feel it, any pain you feel is actually the drug as it enters your system. The mosquito ever so nicely leaves behind the itchies.

Answer 7

mosquito can lead to deadly disease like dengue from which Delhi and other parts of India are suffering. when the acid of mosquito reach our nerves and vessels the we feel pain but,
it is to late.

Answer 8

A mosquito injects a "numbing" agent into your body when it "bites" you. This agent wears off fairly quickly. When it wears off you start to feel the "itch".

Answer 9

i'm not exactly sure, but i think the pain, itching & swelling happens due to ur bodys immune reaction in response to the bite which takes awhile to develop & not because of the bite it's self

Answer 10

I feel it at the time as a pinch. it's not til a few minutes later that the allergic reaction starts and the itch begins.
