Japanese beetles (Popillia japonica) are a significant pest for gardeners and homeowners. Recognized by their metallic green bodies and copper-brown wing covers, these invasive insects can wreak havoc on a wide variety of plants. Here’s a comprehensive guide on how to prevent and battle Japanese beetles in your garden and yard this year.
Identifying Japanese Beetle Damage
Japanese beetles are notorious for skeletonizing leaves, leaving only the veins intact. They are especially fond of roses, grape vines, and lindens but can attack over 300 plant species.
Prevention Strategies
Plant Selection and Maintenance
If Japanese Beetles are a problem in your area, there are some plants that are less attractive to them. Some resistant varieties include boxwoods, dogwoods, and oaks for trees.
Physical Barriers
You can use row covers on susceptible plants during peak beetle activity (June to August). This prevents beetles from accessing and damaging the plants.
Also regularly inspect plants and handpick beetles, dropping them into soapy water to kill them as you find them.

Chemical Controls
Insecticidal Soaps and Oils – Neem oil and insecticidal soaps can deter beetles without harming beneficial insects.
Chemical Insecticides – Use insecticides like carbaryl or pyrethroids for severe infestations. Follow the label instructions carefully! Often times they need to be mixed with water before you disperse it. Our associates at Applewood Nursery & Landscape Supply can help you find exactly what you’re looking for.
Remember to regularly inspect plants for beetle activity and damage and be sure to determine acceptable levels of beetle presence and damage before resorting to control measures. It is best to use a combination of cultural, biological, and chemical controls to manage current and future beetle populations.
