Mosquito pesticides: How to Monitor Spraying Plans in Your City


How to Monitor Spraying Plans in Your City

Compiled by Amy Moonlady Martin, a service of Moonlady News: cultural consciousness for North Texas. Get to know us by signing up for the MWF email digest at

Ground fogging and aerial spray plans for North Texas are constantly shifting. Notifications are almost always at the last minute. Cities and counties can ground fog from trucks at any time and the latest contract with Dynamic Aviation Group allows for periodic aerial spraying in Dallas County without a mosquito emergency being declared.
Moonlady made this page with resources for you to monitor if pesticides are planned for your area. This document can always be located on our Home page or the Community, Home & Garden or Nature sections. If any information is missing, incorrect or a link has gone bad, please Contact Us.
In North Texas, county governments are the main peddlers of mosquito pesticides. Other counties usually take their lead from Dallas County. Sigh. The smaller the city, the more likely they are to default to the county opinion.

What’s in this Compilation:


Dallas County – Main Resources

  • Main Webpage
  • Mosquito Hotline: 214-819-2115
  • To request that your home not be sprayed due to personal health problems with pesticides, in Dallas call 311. They don’t care about your fish or bees, so say that it’s your health at stake. They get concerned if you report respiratory distress, metallic taste in mouth, or vision problems.
Find out what Dallas County areas are to be mosquito fogged or aerial sprayed. – SPRAY MAP – The main mosquito page suggests that residents bookmark it and check regularly. In other other words, they seem to have no plans to send out notifications.

City Mosquito Sites

Bookmark those that apply to you and visit often to check on ground fogging and aerial spraying plans. These sites often give toxic-chemical advice for preventing mosquitoes, so beware, and information about the effectiveness and safety of pesticides on mosquitoes is frequently not very honest. Best green info at Addison and best general info is at Fort Worth. Best prevention practices include Richardson.
Many cities have e-alert systems that are only available to residents. From any of the city pages listed below, click the home page to see if your city does (sign up is usually on the front page). Phone numbers provided go to a mosquito hotline, the department in charge, or the main city line.

Note from Bohemian Utopia I wanted to give the City of Richardson some kudos for the manner in which they have been managing the West Nile testing and treatments so far. Though they did spray our neighborhood earlier in the year – take a look at the interactive map and look at their treatments documented. “Larvacide added to pool on xxx drive”. “fish added to pool on xxx street”., etc etc, etc. They do offer an avenue for complaints about standing water, and appear to be very active on treating said issues
