How Do Mosquitoes Reproduce? Mosquitoes reproduce sexually, and do so after the female mosquito has gorged yourself with blood so that she may utilize its protein rich content in order to produce eggs.
The more blood the female mosquito drinks, the more eggs she can lay. Scientists have found that for every milligram of human blood, she can lay an average of about 40 eggs. A milligram of blood is tiny, smaller than a grain of sand, so even one good bite can give a mosquito enough nourishment to lay hundreds of eggs at once. The eggs are so small, though, that a single raft of 200 to 300 eggs is only 1/4 inch long. Mosquitoes usually lay the eggs at night and the rafts are so inconspicuous, you may never notice them.
