Tips for Your Property From Still Waters Grounds Maintenance

When is the best time to treat for Grubs?
White grubs comprise several different species of beetles but generally are controlled the same way. The damage is caused by the larval stage of the insect's life when it chews on the root structure of grass plants just below the surface. This larval stage is present twice throughout the growing season. First, the insect over winters deep in the soil and works its way to the surface as temperatures rise in the Spring. They begin feeding at this point for several weeks before pupating into the adult beetle stage.  Most beetles will continue to do some damage to ornamental plants during this time.  After several weeks in the adult form, the insects mate and lay eggs just beneath the soil surface. After a short period, the new larvae emerge and begin feeding once again (mid-late August). This is the time when the insects are at their most immature and vulnerable point. Although the available control products vary in their mode of action, this is generally the most effective time to control a white grub population.
