What does the City do to control the mosquito population?
The Health Department follows a comprehensive plan to prevent the spread of the West Nile virus, as recommended by federal, state and local public health and environmental agencies and experts.
- Continuous monitoring of mosquito test pool results.
- Using larvicide along creeks and in stagnant bodies of water to prevent mosquito eggs from developing into adults.
- Abating or eliminating stagnant water
- Public education efforts.
Mosquitoes need water in order to breed and grow into adults. Eliminating any standing water can help control the population. Here are some tips:
- Repair leaky plumbing such as dripping faucets and sprinklers. Don't over water a lawn, as this can cause pockets of stagnant water to develop, particularly in low lying or poorly drained areas of the yard.
- Don't allow birdbaths, swimming pools, pet watering dishes, flowerpots and saucers or other vessels to hold water and become stagnant. Wading pools, buckets in the sand box or a child's wagon can hold enough water for a mosquito to lay her eggs, so store these properly.
- Keep your lawn mowed and tall grass and weeds trimmed.
- Fill in hollows in trees with sand or mortar.
- Keep your gutters cleaned out to allow rainwater to drain properly.
The City of Richardson responds to complaints of stagnant swimming pools. The stagnant water in abandoned, unmaintained swimming pools typically contain algae/nutrients that female mosquitos value when choosing a site to lay eggs.
Health Department staff treat stagnant swimming pools with larvicide to prevent mosquito eggs from developing into adults. The extended release larvicide used is effective for up to 150 days and does not affect other species of wildlife. These treated locations are identified with a sign posted nearby, most likely on the fence around the swimming pool.
The Health Department conducts inspections of public and semi-public swimming pools and spas. An application must be submitted by properties with public or semi-public pool(s) every May (renewals are sent out to existing properties May 1).
Outdoor pools are inspected regularly throughout the swimming season. Indoor pools are inspected periodically year round. Inspections focus on all aspects of pools/spa operations including maintenance, construction, water clarity, chemical balance, fencing, filtration, safety equipment and warning signs.
Improperly maintained swimming pools (public OR private) can be reported to the Health Department by calling 972-744-4080 during regular business hours.
