Area-wide
control of mosquitoes is generally the concern of professional services,
including those obtained by mosquito abatement districts. Personal
protection is usually the consumer's area of control.
Community Control
Breeding Site Management - Water management to
prevent mosquito breeding is essential for effective control. Eggs
cannot hatch without water. Locate standing water and eliminate. Drain
or fill stagnant water pools, puddles, ditches or swampy areas. Fill
tree holes with sand or mortar. Remove tires, buckets, tin cans, jars,
toys and other receptacles so they will not collect rainwater or other
moisture. Mosquitoes can breed in as little as a cup of water. Change
water in birdbaths and wading pools once or twice a week. Clean out roof
gutters. Check the water in flowerpots and other plant containers for
mosquito larvae.
Larval Control (Larviciding) - Attacking the
mosquito problem through larval control is a logical approach to
reducing public health concerns and annoyance. The larval stage is the
only time in the insect's life cycle when it is truly confined and
concentrated. Larvae may be killed off when standing water is treated
with larvacides in the form of briquettes, granules, liquid concentrates
or other controlled released systems.
Adult Mosquito Control (Adulticiding) - Adult
control programs are necessary in areas of disease epidemics such as
encephalitis as may occur in localities with a high density of
mosquitoes, Cutbacks in funding for local mosquito abatement districts
are of concern, especially when weather conditions have encouraged
greater mosquito populations. These methods include: thermalfogging,
effective as a space spray treatment when applied in late evening, at
night or early morning when winds are calmest; ultralow volume
application, with special nozzle adaptations that break up undiluted,
specially formulated insecticides into microscopic droplets; mist
spraying of very fine mist of insecticide in water by blowing machines;
and residual spraying as a barrier zone to tall grasses, weeds and
shrubs, with effectiveness of several days.
