Pyrethrin insecticides have been used in agricultural and equine applications for a quarter century with no known harmful effects. Pyrethrin is used on dogs in products such as flea and tick dips.

Your purchase includes a 2-year warranty on the equipment and labor as long as you use Pyrethrin insecticide in your system. Our maintenance instructions will help extend the life of your nozzle tips in hard water areas. There are thousands of Pyrethrin customers who have enjoyed years of service from their systems with little or no need for replacement parts. We do stock a complete line of parts for any unexpected occurrences.

Let nature be your guide. We always start our systems with 2 sprays a day for about 35 seconds. If necessary we can adjust later. As different pests swarm or become active, you may increase or decrease the number of sprays you use. You should never need to exceed 6 times per 24 hour period. Some other insecticides require you to spray every hour or hour and a half. This will never happen with Pyrethrin. You use less insecticide, so you save money.

Our team handles all maintenance, including refills, system checks, and winterization, ensuring continuous and effective mosquito control. ​

The frequency of refilling your system will depend on the number of spray nozzles installed, the number of sprays per 24 hours, the severity of the insect problem and the length of each spray cycle. Lawns Unlimited, Ltd. will furnish each customer with a chart that will show you exactly how long a tank of chemical will last based on a particular spray cycle. The system shuts itself off when there is two or three inches of liquid left in the tank.
