Parkway Trees

Homeowner attention needed
Last year, Japanese beetles ravaged many of our trees including parkway trees. Residents are reminded that they are responsible for all trees within their lot including the parkway. The HOA's landscaper recommends that all homeowners spray effected trees.

Chemical Control - Insecticide Spraying
Adult beetles can be controlled by spraying susceptible plants with insecticides. Over-the-counter pesticides generally need to be made 20 days before anticipated Japanese beetle activity. During the heavy adult activity periods, sprays may be needed every 5 to 10 days.

Cultural Control - Hand Picking
By noticing when the first adults arrive on a property, you can pick off and destroy these scouts that attract additional pests. The adults are less active in the early morning or late evening. They can be destroyed by dropping into a container of soapy water.

Cultural Control - Plant Non Attractive Plants
The adult beetles do not like to feed on arborvitae, ash, boxwood, dogwood (flowering), euonymus, false cypresses, firs, hemlock, hydrangeas, junipers, magnolias, maple (red or silver only), mulberry, oaks (red and white only), pines, sweet pea, or yews. Consult your landscape professional or John White at the Village of Streamwood for advise on what to plant.

Cultural Control - Trapping
Several traps using a floral lure are available. These traps are not recommended for general use unless special conditions can be met. The traps have been demonstrated to be effective in reducing damage and populations only when landscapes are isolated from other Japanese beetle breeding areas or when mass trapping (everyone in the neighborhood) is used. In most urban areas, traps tend to attract more beetles into the area than would normally be present. In this situation, adult feeding and resultant grub populations are not reduced.
