Misting System Questions

Questions About Mosquito Misting Systems

Here are 10 very important questions to ask a salesman before you buy any pesticide misting system.
Using only certified or licensed pesticide applicators is highly recommended for installation of mosquito misting systems, whether this is required in your state or not.

Don’t be fooled by sales people who claim that their chemicals are 100% safe, “organic” or “all natural.”  If a chemical kills insects, it is an insecticide, whether or not it is “natural.”  The most commonly used ingredient in most systems is the botanical insecticide pyrethrum, also called “pyrethrins.”  Though relatively safe to most people, some people find pyrethrins irritating.  For a few people, pyrethrins may trigger a cough or irritation that can provoke an asthma attack.  Even “natural” insecticides will kill butterflies and other beneficial insects in your garden, especially if sprayed during the day.

You should be given a product label and MSD sheet. Read it and keep a copy where you can find it easily.   Labels contain essential safety and use information about the insecticide.  Don’t permit a company to use any product that states on the label that the product is “Not for use in outdoor residential misting systems.”
Mister nozzles should be directed away from sensitive places such as pools, fish ponds, natural streams and other sensitive sites.  Timers should be set to avoid applications when people are nearby.
Mister system nozzles should be installed at or below a six-foot height to minimize drift.
Since most mosquitoes are most active at dawn, dusk and during the night, systems that come on during these times will be most effective.  Also, nighttime operation should minimize chances that pesticides will contact people, pets or beneficial insects.
All pesticide tanks should be secured with a lock. Information about how the pesticide should be added, and diluted, and any additional necessary safety precautions, should also be clearly posted on the unit.
Maintenance is a hidden cost of mister systems that is easy to overlook. Plan for nozzle and line inspections, pump maintenance, refilling of insecticide tanks and timer adjustments at least annually.
You should be assured to hear that an installer follows NPMA/ASPCRO [N.P.M.A. and ASP crow] recommendations. These recommendations were designed by responsible companies and state regulators with your family’s safety in mind.
