Olson Tree Care
While the adult life cycle of the Japanese Beetle is over at the end of the growing season, it is always a good time to look ahead.
Arborist knowledge of favored trees is required to choose the correct Tree Service.
Some of the most common trees to suffer dieback from the Japanese Beetle in Des Moines, Iowa are the River birch (Betula nigra), Paper birch (Betula papyrifera), Linden or American basswood (Tilia americana). While many other trees are favored, these tend to have higher populations that may require pest management by Olson Tree Care.
What should you do?
- Some Tree Services believe that treating the soil, attempting to reduce the grub life of the Japanese Beetle, is the way to go. The Arborist at Olson Tree Care in Des Moines, Iowa has found this effort is futile. The population does not stay specific to the tree it emerges near. They migrate well to new locations meaning that reducing populations in the soil only reduces the number in whole for an area, not a tree specifically.
- Spraying would be another futile endeavor. Arborist Treatments have very little residual effect and limited population control.
- The best Tree Service Olson Tree Care has seen on high value and high risk trees is trunk injection with AceJet. Acejet is a quick acting knockdown insecticide with a short residual. When done by an Arborist in a timely manner, the tree will have a good 30 days of protection from the short life cycle of the adult Japanese Beetle.
