Dane County will be quarantined after Emerald Ash Borer (EAB) was confirmed on the north side of Madison near Warner Park.

The quarantine prohibits some wood products from being moved out of the county to areas that are not infested.

Here's what homeowners should do about their own privately owned trees:

1. Visit these websites for detailed information:



2. Keep a close watch on ash trees for signs of possible EAB infestation: thinning canopy, D-shaped holes in the bark, new branches sprouting low on the truck, cracked bark and woodpeckers pulling at the bark to get to insect larvae beneath it.

3. Call a Certified Arborist for expert advice.

4. If you are considering preventative treatment, the city of Madison encourages you to use the injection method rather than the soil drench method in order to protect our lakes and ground water.
