City of Stevens Point Continues Treating Ash Street Trees

Emerald ash borer was found in Stevens Point in 2016. On Mon., June 18, City Forestry personnel and Trugreen will begin treating 550 ash trees in the rights-of-way. Residents who have ash trees on their property should look into having the trees treated.

Trees smaller than about ten inches in diameter can be successfully treated with products bought at home and garden centers. Products such as Ortho Bug B Gone Year Long Tree and Shrub Insect Control, or Bayer Advanced Tree and Shrub Protection are examples of insecticides labeled to control EAB.

The active ingredient essential to controlling EAB is imidicloprid. it is important to  follow the product's directions. A demonstration video of using one of these products can be found at https://www.youtube.com/watch?v=wLEVxteP7OQ.

There are other insecticides that are effective in protecting larger ash trees, but they require special training and certification to apply. Residents who have an ash tree larger than ten inches in diameter should get an estimate from more than one certified arborist to have their ash tree treated.

Ash trees in Stevens Point left untreated will be infested to some degree within five years, and will begin to die off in large numbers within ten years.
