Japanese beetles (Popillia japonica) have become a major pest in Eastern North America and other places. The Japanese beetle trap is routinely recommended for garden use and is easily available commercially, but does it work?
One of the problems with this trap is that it does “seem” to work – it catches lots of beetles. But does it bring all the neighborhood beetles to your yard? Will a Japanese beetle trap reduce the damage this pest does to your roses and other tasty plants?
The answer to these questions is a bit more complex than you might think.
