Emerald Ash Borer Update
The emerald ash borer (EAB) has been found in Champaign County at Prairie Pine Campgrounds in Rantoul and in Grundy County at the Three Rivers Rest Area on I-80 in Morris.

Magnolia Scale
Magnolia scale is heavy this year in northern and central Illinois. It is susceptible to control from now into spring.

Whitefly adults are very common on many outdoor different plants. At this time of year, they are unlikely to cause serious damage to temperate plants.

White Grubs and May Beetles
White grubs are still susceptible to treatment until the soil temperature in the turf root zone drops below 60 degrees F. That is the temperature at which Japanese beetle grubs descend deeper into the soil for the winter.
