Mosquito prevention measures

PREVENT SOURCE BREEDING (most effective) – Dump stagnant water from gutters, old tires, pots and small containers.  Cover rain barrels and change bird bath water daily.  Contrary to popular belief, creeks and green swimming pools are not likely harborage areas for mosquitoes.  Mosquitoes prefer small containers out of the sun and wind.  A 3” potted plant tray can produce hundreds of larvae.

AVOID MOSQUITOES AT FEEDING TIME (effective) – Try not to be outside late in the evening (dusk) when female mosquitoes are searching for a blood meal.  The majority of attacks occur at this time.  If you must go out, wear repellant containing DEET and long sleeves and pants.  Make sure screens and exterior doors are closed and in good repair.

PESTICIDE TREATMENT AND SPRAYING (least effective) – Put out citronella candles; spray adultacide (mosquito spraying) and larvacide (kill larvae before they hatch).  Spraying is not as effective as most think, because the applied pesticide must come in direct contact with adult mosquitoes to effectively kill them.  Since applications are from the road, most mosquitoes in the back yard are not affected.  Preventing mosquitoes from breeding is a much more effective method of control than trying to fight hundreds of thousands of them after they reach adulthood.
