Please be sure to read the product label of any insecticide you choose to use to get information on the personal protective safety gear you will need. In most situations, it is recommended that you wear long pants, a long sleeved shirt, closed toe shoes with socks, chemical resistant gloves, and goggles. In areas where ventilation is poor, a manufacturer may recommend you wear a mask or a respirator. We have put together two different safety kits that will make selecting the correct safety gear easier for you.
If you have done a thorough inspection and determined you have enough crane fly larvae for control measures, and your lawn is suffering from crane fly damage, control is likely necessary. Natural predators and insecticides are good options for getting rid of crane fly larva.
Encourage Natural Predators
If you have a moderate population of these pests in your turf, encouraging birds to your lawn, especially in winter and spring, can drastically cut down on populations.
An insecticide application will kill the crane fly larvae in your turf. There are several products available labeled to control European crane fly larvae, in liquid or granular formulas, that can be applied to your turf.
Products containing imidacloprid and pyrethroids are popular ingredients. Make sure to follow all directions and read cautions and warnings carefully.
Optimal control will be achieved when applied in late summer or early fall, soon after eggs hatch. You can also apply these products in the spring, once temperatures begin to rise.
Always read the label for proper application timings and rates.
