A: Yes, grubs in lawns are a common occurrence in Florida, but this does not necessarily mean that one’s lawn is populated by grubs. You can confirm grub infestation by pulling on a patch of grass. If it is easily removed and if grubs are found in the soil below, then you have grubs.

Most of the grub worms found in Florida lawns are immature Scarab beetles. They are also immature May beetles (subfamily Melolonthini) which are often called June bugs. Other common grub worms are larvae from Japanese beetles (Popillia japonica Newman) and Green June beetles (Catinis nitida Linnaeus).
They are whitish in color with dark areas at the rear and a brownish head. The adults are beetles. The adults lay eggs in the soil. Grubs live in the soil and feed on roots of many different plants.
When your yard is under attack by grubs, grass will thin and turn brown. This leads to visible larger brown patch areas in your yard. It’s common to notice these odd-shaped brown patches in late summer or early fall. During this period, grubs amp up their eating, and the damaged and dead grass becomes more visible.
When the ground warms up in spring, they resume feeding and can cause damage from the time the grass turns green until they pupate in mid-May. Grub damage may appear in home lawns from mid-September to November or from March to early May.

If you suspect that white grubs may be munching away at your turfgrass you can check by cutting down about 2 inches into the turfgrass at the edge of an off-colored area. Cut around three sides of a 1-foot square piece of sod and then pull back the flap of sod you’ve cut free.
Grub worms damage your lawn by feeding on the roots, and eventually turn into adult beetles that eat the leaves of other prized plants in your garden. Many homeowners simply treat their lawn with a chemical grub control product, or grub killer, once or twice a year.
Grubs feed on the roots of grass plants, causing lawns to wilt and turn brown as a result of this feeding. Larva of sod webworms are actually caterpillars that feed on the leaf blades of grasses. The adult is a small, buff-colored moth that flies out of the lawn when disturbed and lands a short distance away.
Grubs aren’t toxic to eat and can, in fact, be eaten safely by people and animals, but only if they’re from sterilized soil. As the grub worms develop, they dig through the soil they live in, ingesting it as they go, says the University of Florida Entomology & Nematology.
Symptoms of an infestation include general thinning or yellowing of turf, which is very similar to other pest infestations like chinch bugs, for example, drought or nematodes. One way to determine a grub worm infestation is to step on the turf in the spring and see if it feels spongey or bouncy.
Grubs are burrowers, and can only be found below the dirt around the Acorn Tree. While hanging out near the tree, Grounded players can collect sap and acorn bits for crafting too. Grubs will sometimes hide below acorns, under roots, and in other dark areas.
The best time to apply grub control is between early spring and late summer when there’s increased grub worm activity in your lawn. For grub preventers, apply between June and July just before they hatch while for grub killers, apply the treatment from spring when you see signs of grass damage.
Because GrubEx targets the larval stage of many insects, the best time to apply it is when the beetles burrow into lawns to lay their eggs — in spring to early summer. When the eggs hatch, GrubEx kills the emerging larvae so they cannot develop into mature insects.
These include milky spore, neem oil, and nematodes — available at most garden centers.
