You have no experience with them.

"Unfortunately, research conducted at the University of Kentucky showed
that the traps attract many more beetles than are actually caught.
Consequently, susceptible plants along the flight path of the beetles
and in the vicinity of traps are likely to suffer much more damage than
if no traps are used at all."

"In most landscape situations, use of Japanese beetle traps probably
will do more harm than good. If you experiment with traps, be sure to
place them well away from gardens and landscape plants."

this was but one of many different studies where their findings were
the same.

In our study, which we chose not to publish due to reasons connected
with our funding, we determined how one out of every four Japanese beetles
attracted to the trap actually escaped the trap. *Those beetles attracted
to the trap who escaped the trap laid their eggs in the nearby lawns and
created serious lawn destruction resulting from grubs.

Not talking about japanese beetles and trapping them.
We're talking about flys.
