The best weapon is your hand. Keep train your hand-clapping and mosquitoes' sound detection of your ear.

Oh - hey neighbor!

I mean, "Hey dere, neighbor!"

With all the rain we've had, I'm surprised the mosquitoes aren't a plague by now. So far, it's just gnats.

According to Wikipedia, a mosquito can hold up to three times its own weight in blood, and they weigh up to 2.5 milligrams. Ergo, a mosquito could drink up to 7.5 milligrams of blood, assuming it does not have any blood in its system already.

Blood has a mass of 1060 kg/m^3. This means 7.5 milligrams of blood is about 0.007ml.

A healthy person can lose about 15% of their blood without any ill effects, which corresponds to about 750 milliliters. This amount of blood loss would require at least 106,000 mosquitoes.

You can still lose more blood than that and survive if you get medical attention quickly enough, as much as 40% or 2 liters. This means about 283,000 mosqutioes would be necessary.

All of this is assuming no blood gets replenished during the process. For every milliliter that gets replenished, you'd need at least another 141 mosquitoes to reach that level of blood loss.

You also have to factor in that only female mosquitoes bite, and that it's unlikely that none of them have any blood in their system, so you'd have to at least double those numbers before there is even a risk of problems from simple blood loss. Whether or not that is a realistic number of mosquitos in a swarm, I have no idea.

My grandfather swore by the marmite defense. Eat a shedload of marmite.

I live on almost the same latitude as you with just as much lake front but alas I have the mines thus the bats thus the solution.

And here is a nice sign for you. :D

Thanks. I appreciate the time that you put into that.

Are they in a cave under your house... Bruce?

Electric racket.

Avoid using it near your collection of fine art.

You'd expire from the toxins in the bite before you died from blood loss. I remember when I was a kid, one of the other kids on a camping trip got extremely sick from being bitten a huge number of times by flies and mosquitoes.

Here we go! XD
One of my favorite bits of all time and a perfect addition to this thread.

I wanna ask, "No kidding? That really works?" But then a big part of me remembers all of the bites on my legs over the years and instead asks, "No kidding? That really works?"
