Beetles are eating my sycamores, service berry, roses, and other plants. What can I do to protect my plants?

Hello Larry,

To properly answer this question, we'd have to know what species of bug is eating your plants. The plant species that you have listed are quite diverse and don't share a tremendous number of pests. I'd be happy to help you identify insects on your plants if you have any clear pictures.

Hi,

This is what I found on the roses. They are the same on the Sycamores.

Hey Larry,

These are Japanese beetles, which do eat a ton of different things! Below is some text that I took from our Japanese beetle publication

"Many insecticides are labeled for use against adult Japanese beetles. Examples include pyrethroid products such as cyfluthrin (Tempo, Bayer Advanced Lawn & Garden Multi-Insect Killer), bifenthrin (TalstarOne, Onyx), deltamethrin (Deltagard), lambda cyhalothrin (Scimitar, Spectracide Triazicide), esfenvalerate (Ortho Bug-B-Gon Garden & Landscape Insect Killer) and permethrin (Spectracide Bug Stop Multi-Purpose Insect Control Concentrate and other brands). Carbaryl (Sevin and other brand names) too is effective. The pyrethroid products generally provide 2-3 weeks protection of plant foliage while carbaryl affords 1-2 weeks protection. For those seeking a botanical alternative, Neem products such as Azatrol or Neem-Away (Gardens Alive), or Pyola (pyrethrins in canola oil) provide about 3-4 days deterrence of Japanese beetle feeding. Insecticidal soap, extracts of garlic, hot pepper, or orange peels, and companion planting, however, are generally ineffective."

Hopefully this helps!
