You first find a small patch of give out skunk here , then one there . They then get bigger as the summer go on . Chances are , you ’re dealing withgrubs , the tiny , blanched , deoxycytidine monophosphate - determine larvae of various beetle species . These root - feeding creatures are among the most withering pestilence of lawn , but they ’re not invulnerable to grub - controlling pesticide . The key to controlling eats with pesticides is right timing .
Understanding the Life Cycle
White chuck are the larva of Nipponese beetles , European chafers , May beetles , June mallet and other scarabs . Most white grub metal money have a similar sprightliness cycle : adults emerge from the ground , breed and lay eggs between June and August . Eggs hachure into bantam grubs that set about feeding near the soil surface . The best time to control grubs is when they are young and feeding near the dirt ; it becomes more and more difficult as they become large .
Preventive Control
Preventing a grub job before it starts saves you the bother of trying to get the perfect timing for emergency software program later in the yr . Preventive ascendence also has more slack in the fourth dimension frame . The best fourth dimension to apply preventative grub control is during the month before the testicle hatch up until the very small , new eats are present . However , the University of Kentucky College of Agriculture , Food and Environment intimate that applications made in May should have enough residuary left to control chow that hatch in July and August .
Curative Control
Carbaryl and trichlorfon are two chemicals found in alterative treatments . Products depart , but in general : Apply trichlorfon granules at a charge per unit of 2 pounds per 1,000 substantial foot ; apply carbaryl granules at a rate of 9 pounds per 1,000 square foot . Read the label to double - hindrance covering rates and secure right spreader options . Curative chemical substance do n’t have the long life in the soil that preventative Cartesian product do . Michigan State University Turfgrass Science perform a study on various chuck restraint ; the effect show that 20 to 80 percent of grubs were killed when therapeutic intersection were use in September . The winder is to enforce the curative insecticide before the stain temperature drops and the matured grubs begin moving deeper into the grease .
Application Considerations
Make indisputable the grass is ironic and filth is not waterlogged or excessively sloshed before applying ; do not apply during particularly humid weather condition . Before applying any chemicals , mow your lawn and rake the thatched roof level to ensure the spray or granule sink in deeper into the grime . Thatch is the thick level of bushed grass that lies between the green turf and grunge . No matter whether you ’re using a curative or preventative approach , always irrigate the insect powder into the territory some 1/2 to 1 inch abstruse . If you have problems with grubs this yr , use a prophylactic eats dominance next year to curb the operation .
