Mosquito Control

The City of Granbury will provide periodic spraying for mosquitoes as deemed necessary, depending upon insect population and weather conditions. Trained City staff use chemical fogging to help control the mosquito population. Spraying is not done in rain or mist. 

Spraying will begin in early June, and continue through September. Spraying is done only when the temperature is above 65 degrees and winds are between one and ten miles per hour.  City staff tries to schedule spraying between 8:30 p.m. and 12:30 a.m., when fewer people and pets are outdoors. 

For mosquito spraying, the City is divided into five sections. One section is sprayed in an evening.   Mosquito Spraying Map

What should I do during the spraying? You do not need to do anything. If you want to take extra precautions, you can refer to these suggestions: 

• Remain indoors with children and pets and cover any ornamental fish ponds, beehives or organic gardens. Stay indoors at least an hour after spraying has concluded.

• Close windows and doors, and turn off window-unit air conditioners or set to recirculate indoor air only.

• Do not let children play near or behind truck-mounted applicators when spraying is taking place.

• Drive cautiously around the spray vehicle and pass it with care.

• Avoid eye or skin contact with the spray if you are outside, and wash any exposed skin with soap and water if you come in contact with the spray.

What Residents Can Do

Mosquito spraying will not eliminate mosquitoes completely. The City asks that residents take action to help prevent mosquito infestation as well. Residents should empty and replace outside water sources for pets daily to prevent ingestion of sprayed chemicals. Other areas of outdoor standing water should be eliminated, when possible, to remove favorable mosquito breeding conditions. These include planters, buckets, tires, children’s swimming pools, gutters, etc. Chemical “donuts” are available at hardware and home improvement stores for residents to purchase to place in detention basins and abandoned pools.

Mosquitos are most active at dusk and dawn. Residents can protect themselves from mosquito bites by applying an insect repellant containing DEET and by wearing protective clothing.
