Life cycle description from the EPA:
All mosquito species go through four distinct stages during their life cycle:
egg – hatches when exposed to water
larva – (plural: larvae) “wriggler” lives in water; molts several times; most species surface to breathe air
pupa – (plural: pupae) “tumbler” does not feed; stage just before emerging as adult
adult – flies short time after emerging and after its body parts have hardened.
The first three stages occur in water, but the adult is an active flying insect. Only the female mosquito bites and feeds on the blood of humans or other animals.
After she obtains a blood meal, the female mosquito lays the eggs directly on or near water, soil and at the base of some plants in places that may fill with water. The eggs can survive dry conditions for a few months.
The eggs hatch in water and a mosquito larva or “wriggler” emerges. The length of time to hatch depends on water temperature, food and type of mosquito.
The larva lives in the water, feeds and develops into the third stage of the life cycle called, a pupa or “tumbler.” The pupa also lives in the water but no longer feeds.
Finally, the mosquito emerges from the pupal case after two days to a week in the pupal stage.
The life cycle typically takes up two weeks, but depending on conditions, it can range from 4 days to as long as a month.
The adult mosquito emerges onto the water’s surface and flies away, ready to begin its life cycle.
[Please let us know if you try this non-toxic mosquito elimination method… and give thanks we don’t have the biting population New Orleans does!] By Susan Langenhennig, The Times-Picayune, May 27, 2014
If you’re waging war on mosquitoes, don’t waste your money on a bug zapper. They aren’t much of a solution. You’re more likely to catch moths than mosquitoes in the buzzing devices, and, as the New Orleans Mosquito, Termite and Rodent Control Board says, “bug zappers do more harm than good.”
If you want a DIY weapon for your fight against the bite, Dan Rojas of GreenPowerScience.com has an easy, inexpensive trap that’s both effective (it will kill thousands of mosquitoes in just 24 hours) and gratifying (you take the battle to the bugs without lifting a bottle of DEET).
In a video posted on Ebaumsworld.com, Rojas uses magnets to attach a mesh screen to the back of a standard-issue box fan, the kind you can find in any big-box home improvement store….

Scenes from our successful June 25 picnic on a beautiful afternoon in Hoopes Park, including excellent conversation and supportive remarks from our good ally Mayor Carolyn Comitta:
Little Faces Chidcare Summer Camp kids made a total of 5 colorful posters for Dontsprayme to illustrate our principal messages. See artists and posters below.
(Feel free to tailor your own message. Example below.)
We applaud the Chester County Health Department and US Environmental Protection Agency for their commitment to reducing pesticide risks:
“The Chester County Health Department is a member of the Environmental Protection Agency’s Pesticide Environmental Stewardship Program. This program requires participants to affirm that environmental stewardship is an integral part of their integrated pest management (IPM) practice, use current, comprehensive information regarding the life cycle of mosquitoes within their IPM program, educate the community on the benefits of IPM, and demonstrate a commitment to pesticide risk reduction activities.”
(Wording from the County’s 5/19/16 release under the heading “Make your home a Mosquito-FREE zone” at CHESTER COUNTY HEALTH DEPARTMENT).
from the Chester County Health Department Rules and Regulations:
502.5.1.1. No person shall maintain or permit to be maintained any pond, privy vault, cesspool, well, cistern, rain barrel, individual sewage system, community sewage system, or other receptacle or system containing water, unless such receptacle or system is constructed or maintained in a manner to prevent the breeding of mosquitoes, flies, or vectors of disease.
