Tri-State area extension agents had some tips for controlling Japanese beetles:
- Don't use traps. Although some people swear by them, extension agents say the traps actually lure more beetles to your yard. The traps catch the males, but leave the females free to lay eggs in your yard, setting the stage for a problem the following year.
- Cover small trees or shrubs, especially young ones, with cheescloth or some other type of netting.
- Spray or dust with pesticides such as Orthene, Sevin and Methoxychlor. Make sure you follow the directions on the label. The pesticides shouldn't be used on blooms or some ornamentals. Spraying on a hot day could burn the leaves.
- If you don't like to use chemicals, use an organic pesticide like Rotenone. One drawback: it must be applied about every other day.
