how to inject mosquito spray in sprinkler system

Injecting mosquito spray into a sprinkler system can be an effective way to distribute insecticide throughout your yard and keep mosquitoes at bay. Here’s a step-by-step guide on how to inject mosquito spray into a sprinkler system:

Materials You’ll Need:

  • Mosquito spray concentrate or insecticide suitable for use in a sprinkler system.
  • Appropriate injection system or kit designed for your specific sprinkler system.
  • Access to the sprinkler system control panel or valve.


  1. Choose the Right Insecticide:
    • Select a mosquito spray concentrate or insecticide that is labeled for use in sprinkler systems. Ensure it is safe for the environment and any plants in your yard.
  2. Install the Injection System:
    • Acquire and install an injection system or kit that is compatible with your sprinkler system. These systems typically include a chemical reservoir, injection pump, and tubing.
  3. Locate the Injection Point:
    • Identify the appropriate injection point in your sprinkler system where the insecticide will be introduced. This is typically a part of the main water line leading to the sprinkler heads.
  4. Prepare the Insecticide:
    • Mix the mosquito spray concentrate or insecticide according to the manufacturer’s instructions. Ensure the solution is well-mixed and ready for injection.
  5. Connect Tubing:
    • Connect the tubing from the injection system to the injection point on the sprinkler system. Follow the manufacturer’s instructions for proper installation and sealing to prevent leaks.
  6. Prime the System:
    • Prime the injection system by filling it with the prepared insecticide solution. This may involve opening valves or adjusting settings on the injection pump.
  7. Set Injection Rate:
    • Adjust the injection rate on the pump to the desired level. This determines how much insecticide is injected into the sprinkler system per unit of time. Follow the manufacturer’s guidelines for the correct injection rate.
  8. Activate the Sprinkler System:
    • Turn on the sprinkler system through the control panel or valve. The injected insecticide will mix with the water as it flows through the system.
  9. Monitor and Adjust:
    • Observe the mosquito spray being distributed through the sprinklers. Make any necessary adjustments to the injection rate to achieve the desired coverage and mosquito control.
  10. Schedule Regular Applications:
    • To maintain mosquito control, establish a regular schedule for injecting the mosquito spray into the sprinkler system. The frequency of applications may vary depending on the insecticide used and local mosquito activity.
  11. Safety Precautions:
    • When handling insecticides, always wear appropriate personal protective equipment (PPE), such as gloves and eye protection. Follow safety guidelines provided by the manufacturer.
  12. Keep Records:
    • Maintain records of when you apply the mosquito spray and the injection rate used for each application. This information can help you fine-tune your mosquito control efforts.

Injecting mosquito spray into your sprinkler system can be an effective way to treat a large area for mosquito control. However, it’s essential to use the appropriate equipment, follow safety precautions, and choose insecticides that are safe for your specific application. If you’re unsure about any aspect of the process, consider consulting with a professional pest control expert or your local agricultural extension office for guidance.
