Japanese Beetle Control
Professional japanese beetle control services in Denver & the Front Range
Japanese beetles are among the most destructive garden pests in Colorado. Adults skeletonize leaves and flowers while their grubs destroy lawns from below. Our seasonal treatment programs attack both life stages for comprehensive protection.
The Japanese Beetle Life Cycle
Understanding the beetle's life cycle is key to effective control. Grubs feed on grass roots from fall through spring. Adults emerge in late June through August, feeding voraciously on over 300 plant species. They lay eggs back in lawns, continuing the cycle. Effective control targets both stages.
Grub Prevention & Treatment
The most effective long-term strategy is preventive grub treatment applied in late spring or early summer before eggs hatch. This breaks the life cycle and reduces next year's adult population. For active grub infestations, we use curative treatments that work within days.
Adult Beetle Management
For active adult beetle infestations, we apply targeted foliar treatments to protect your valuable plants. We avoid beetle traps, which research shows actually attract more beetles to your property than they catch. Instead, we focus on direct treatment of affected plants and areas.

Frequently Asked Questions
When is the best time to treat for Japanese beetles?
Preventive grub treatment is best applied in May-June before eggs hatch. Adult beetle treatment is done in July-August when beetles are active. We recommend a seasonal program that covers both stages.
Should I use Japanese beetle traps?
We don't recommend beetle traps. Research by the USDA shows they attract 5-10 times more beetles than they capture, actually increasing damage to nearby plants.
Will grub treatment harm my lawn?
No. Our grub treatments are applied at rates that target grubs specifically and are safe for your lawn, pets, and the environment when applied as directed.
How many treatments will I need?
Most properties benefit from 2-3 treatments per season: a preventive grub treatment in late spring, and 1-2 adult beetle treatments in summer as needed.
