The best way to fend off mosquitoes is to apply a repellent with 15-50 percent DEET, 20 percent picaridin or 30 percent oil of lemon eucalyptus. Repellents with lower percentages are not as effective.
Mosquitoes are incredibly well adapted for living on Earth in extreme conditions. They exist at 8,000 feet in the Himalayas and below sea level in the California desert. The eggs of mosquitoes can survive months to decades in desert, frozen tundra and even on dried flowers.
When it rains, the eggs hatch immediately, releasing mosquito larvae. Water reduces the amount of oxygen available to the eggs, which triggers hatching. Mosquitoes’ normal diet is nectar and aphid excrement. Blood is ingested only to fulfill reproductive needs. Mosquitoes become sexually mature at 2 days old and mate in swarms at dusk or dawn.
