Understanding the Enemy: Japanese Beetle Life Cycle and Behavior
Before waging war, it’s crucial to understand your opponent. Japanese beetles have a one-year life cycle, with the majority of their lives spent underground as grubs.
- Eggs: Adult females lay their eggs in the soil in late summer.
- Grubs: The eggs hatch into white grubs that feed on grass roots throughout fall and spring.
- Pupae: In late spring, the grubs pupate and transform into adults.
- Adults: Adult beetles emerge in early summer and begin feeding and mating, continuing the cycle.
Understanding this life cycle allows you to target your control methods effectively at different stages of their development.
Effective Methods to Control Japanese Beetles
Here’s how to get rid of Japanese beetles in Colorado using a multi-pronged approach:
1. Handpicking: Simple yet Effective
Handpicking might seem tedious, but it’s a surprisingly effective way to eliminate small infestations. Early morning is the best time for this, as beetles are less active.
- Technique: Knock beetles into a bucket of soapy water, where they’ll drown.
- Consistency: Repeat this daily during peak season for optimal results.
2. Physical Barriers: Protecting Vulnerable Plants
For prized plants, consider physical barriers:
- Row Covers: Lightweight fabric barriers allow air and light while preventing beetles from reaching your plants.
- Netting: Use fine netting around plants, especially for fruit trees and berry bushes.

3. Biological Controls: Enlisting Natural Enemies
Introduce beneficial insects and microorganisms to your garden:
- Nematodes: These microscopic organisms attack and kill Japanese beetle grubs in the soil.
- Milky Spore: This naturally occurring bacterium infects and kills Japanese beetle grubs, providing long-term control.
4. Insecticides: A Last Resort
While insecticides should be a last resort, they can be effective in severe infestations.
- Contact Insecticides: Kill beetles on contact but require thorough coverage and repeat applications.
- Systemic Insecticides: Absorbed by plants, making them toxic to beetles that feed on them.
Important Note: Always choose insecticides that are labeled for use against Japanese beetles and follow the instructions carefully. Consider their impact on beneficial insects and the environment.
Long-Term Prevention: Winning the Battle Before It Begins
Preventing future infestations requires a proactive approach:
- Healthy Lawn Care: Maintain a healthy lawn through proper watering, mowing, and fertilization to make it less attractive to grubs.
- Fall Cleanup: Remove fallen leaves and plant debris, as these provide hiding places for overwintering adults.
- Traps: Strategically place Japanese beetle traps away from susceptible plants to lure and trap adults.
