Emerald Ash Borer

Q. I have ash trees on my property that are doing poorly and haven't been healthy for the last few years. Do I have Emerald Ash Borer?

Controlling Japanese beetles

Q:  How do I control Japanese beetles?

A:  The best way to control Japanese beetles is to knock them into a jar of soapy water. Allow them to sit overnight in the water and discard them. Severe infestations can be chemically treated. Please contact Plant Information Service for the most current recommendations. Japanese beetle traps are not recommended, as they will attract beetles from the surrounding area to your garden.

Controlling ants

Q: Ants are all over my trumpet vine and garden in general. Is there an environmentally safe way to remove them?

A: Wet weather is likely the cause of an unusual pattern of behavior in the ants around your home. Frequently saturated soil drives ants up and out of their colonies. They are attracted to the trumpet vine because it produces abundant nectar. The ants will cause no harm to your plants. A garden hose can be used to spray them off the plants.

Insect leaf damage


Q. I’ve noticed many leaves of my plants look chewed. What is causing this and is there anything I can spray to help my plants? 

 A. At this time of year, many different types of insects and their larvae frequently feed on the leaves of plants. Without seeing the culprit, it is not possible to determine which insect is causing the damage to your plants. Inspect your plants thoroughly in order to positively identify the insect causing the damage.
