The Q&A Archives: garden pests

Question: pests are eating the leaves of my roses and periennials. what is the best way to deter them and save my plants?

Answer: You didn't describe the pests so I am not certain what is bothering your plants. However, it is time for the metallic colored Japanese beetles to appear for the year and they will eat foliage as well as damage flowers on a wide variety of plants. Sometimes they can be repelled using a spray containing neem, but they are difficult to control as they fly very long distances. Carbaryl (the ingredient in Sevin) will kill the beetles it contacts, but has no residual action so its usefulness is a bit limited. It is important to get a firm identification of the pest before you try to treat for it. Your local county extension may be aware of local infestations and can help you identify the insects. Based on that knowledge, they can recommend the best control measures.
