Mosquito Information

Basic Facts
Home Range
Asian Tiger Mosquitoes are limited to a flight range of about 300 feet from their breeding ground while most other species have a home range of 1 to 3 miles from their breeding ground.

Life Span
Male mosquitoes live for 10 to 20 days, but most adult females can live up to 100 days.

Development
Mosquitoes only take 4 to 7 days to develop from an egg to adulthood. This means that breeding grounds only need to be present for a week for mosquito eggs to hatch.

Prevention & Protection
Insect Repellant
DEET (N,N-diethyl-3-methylbenzamide) concentrations in products can range from 5% to 100%. According to the CDC (Centers for Disease Control), "Products with <10% active ingredient may offer only limited protection, often 1 - 2 hours...Studies suggest that concentrations of DEET above approximately 50% do not offer marked increase in protection time against mosquitoes; DEET efficacy tends to plateau at a concentration of approximately 50%."
