Most white grubs complete their development in one year. The adult stages of white grubs are
At the adult stage, grub worms turn into beetles that emerge from the soil. The type of beetle species varies based on the type of grub worm present. You may begin to notice beetle damage as they eat the leaves of your grass and other plants in your garden.
Once the ground has thawed and the larvae finish their feeding schedule, they transform into pupae and remain in the soil for several weeks. It's during these last few weeks that the grub grows quickly and transforms into a beetle.
Grubs awaken after winter and immediately begin feeding on tender grassroots when ground temperatures begin to warm. Generally, they turn into pupae in late spring, which then morphs into adult beetles. By summer, these adults emerge from the ground to feast on flowers, trees, and other lawn and garden vegetation.
What Exactly are Grub Worms? As mentioned earlier, grub worms are the immature stage of June Beetles. These pests commonly emerge between March through May and leave their eggs in your lovely lawn. As the white grubs begin to look for nutrients, they'll feed off of the roots of your lawn from June through August.
Grubs are often considered the most reviled lawn pests in the region because their presence can go undetected until significant damage is already done. They live in soil and feed on the tender roots of your grass.
Although many people find June bugs unsettling, they play an important role in helping nutrients cycle through ecosystems. By chowing down on grass roots, June bugs concentrate nutrients into juicy (larva) and crunchy (adult) calorie-rich packages that are consumed by a variety of other organisms.
Spray with a borax mixture.
Some homeowners get rid of grubs by spraying infested areas with a tablespoonful of borax, a common household cleaner, mixed with a quart of warm water. Be careful; borax can damage sensitive plants and your grass if you spray too much or too often.
Skunks and raccoons are not the only creatures that will feed on grubs. Crows will search for them as well.
After all Grubs have been freed and Grubfather is lying in the centre of the room, he can be hit with the Nail. This deals no damage and only makes Grubfather laugh. Down-striking with the Nail causes the Knight to launch extra high.
Grubs are soft-bodied larvae of various beetle species.
These c-shaped insects live underground and survive by eating the roots of grasses and other plants. Their life expectancy is roughly one year, with four unique life stages we'll investigate in detail because they are crucial to defeating grubs.
To kill grubs in the spring or fall, use carbaryl or trichlorfon. Always wear rubber gloves and rubber boots when applying insecticides to turfgrass. Make sure to irrigate the lawn with at least 0.5 inches of water* and allow the grass to dry before allowing anyone or pets into the treated area.
Grubs can be found within your lawn during the late summer months after the beetles have laid their eggs around July. Female beetles lay their eggs about one or two inches deep in the soil. They will spend two to three weeks laying eggs and will each produce as many as 60 eggs in this time.
What are the Signs of Grub Damage? Grub lawn damage looks like big, irregular dead patches of turf. These are areas where the grubs have detached your grassroots, which prevents your lawn from receiving water and nutrients. In turn, these sections of grass die.
Luckily, your lawn can recover! Schedule an overseeding service to help thicken your turf after a grub infestation. By spreading grass seeds across your lawn, your lawn will be filled with new, green grass that will fill in any bare or patchy areas that were caused by grub damage.
The new generation of root-munching pests begins feasting immediately after hatching. Peak feeding occurs in early fall. Typically, the pests operate a few inches below the soil surface, but burrow deeper (up to 8 inches in northernmost areas) before winter arrives.
Here's what grubs are looking for: Moderate temperatures. Grub populations tend to increase during a mild summer into fall. Moist soil.
Chipmunks will create a 2-inch-wide hole, usually mounded about 1 inch. Moles create tunnels, but these are always covered by conical mounds. Pocket gophers also make tunnels, but these mounds are large bean-, fan-, or dune-shaped and have a plugged hole. Both moles and gophers live in tightly sealed burrow systems.
Squirrels are very good about eating a variety of different foods throughout the year. They will eat nuts, berries, seeds, bark, lizards, eggs from other animals' nests, pet food, and leftovers in our trash cans! In addition to this, they also enjoy grubs and worms that can be found underground.
Applying grub control in late spring or early summer, typically between April and June, will help to disrupt the lifecycle. This is when grubs are in their earliest developmental stages, and the treatment will be most effective.
The key to controlling grubs is to kill grubs before they hatch and begin to cause damage to your lawn. In spring or early summer, apply a preventative grub control product, such as Scotts® GrubEx®1 to your lawn, following label directions. This is especially important if you've had problems with grubs in the past.
You can spray biological or botanical pest controls to kill June bugs. The common sprays that are used to destroy these bugs are Bacillus Thuringiensis (BT), Imidacloprid, Diatomaceous Earth (DE), and Chlorantraniliprole.
While these bugs don't sting or bite, they also don't carry viruses like mosquitoes do, so there is no threat to being around one. While they could make your lawn look patchy, they are more annoying than anything if you don't have a garden to worry about.
June bugs are harmless to humans and do not sting or bite. Despite having two sets of wings, they are clumsy flyers and tend to fly into things, including people, as they are moving around in the evenings looking for food and other June bugs.
