Prevent these common Denver lawns pests

From pesky beetles to aggressive billbugs, insects in your Denver lawn or garden can be a major nuisance. Although we all try our best to keep pests at bay, these invasive critters can devastate even the most well-manicured and maintained lawns. Because of this, our team has a few tips on how to spot and prevent an infestation by some of Denver’s most common lawn-destroying culprits.

Scarab Beetles

Commonly known as June bugs, these pesky beetles are often oval-shaped and come in shades of brown, black, and maroon. Because they are attracted to rainy weather, June bugs are typically most active in the months of May and June. While these hairy beetles can be a pain once fully mature, they are most devastating to your lawn during the larvae stage. The flat, white larvae devour foliage and flowers, which can result in patches of dead grass or damaged plants. If you suspect your lawn is falling victim to this ground-dwelling insect, there are natural ways to eradicate it. One of the easiest things you can do is use a natural insecticide, like neem oil or Bacillus Thuringiensis (or Bt). These organic products can help eliminate the larvae without harming the useful bugs in your yard.

White Grubs

White grubs, or lawn grubs, are tiny, c-shaped creatures that are often white in color. These grubs, with soft bodies and legs around their head, feast on the roots of turfgrass. Although they typically live on the top few inches of soil, they can be hard to spot. If you notice small irregular patches of brown, dry, or wilted lawn- you may have the beginnings of an infestation. Another sign of a white grub infestation is if you notice other pesky critters (like crows, raccoons, and skunks) attracted to or digging around these areas. One of the best ways to control and treat this is to attack before the grub eggs hatch. This is often done with an insecticide, although we always recommend you consult a professional, like the team at Growing Green, before trying to treat the area yourself.


Much like White Grubs, Billbugs feed on the root of your grass. These tiny creatures with hard shells burrow down to grass stems and roots and are especially common during drought periods. Because mature billbugs and their larvae can devastate yards, it is extremely important to stop this insect as soon as possible. Regular watering and fertilizing are great ways to prevent and control billbug infestations. However, if these methods do not work, we highly recommend you contact a lawn professional before the problem gets worse.
