Default Question about beetles and grubs

I've seen you hawking that gizmo before.

Here are the facts on bag a bug's.

http://comp.uark.edu/~dtjohnso/japbeetle.html

Japanese beetle traps are sold under the claim that they attract and
remove enough beetles to meaningfully reduce the nearby population and
protect surrounding plants. They do catch a lot of beetles, so they do in
fact reduce the local population, but the magnitude of that reduction is
usually small. If you do use traps in an effort to control this insect,
use several (not just 2 or 3), and place them a little ways away from the
plants you hope to protect most -- more beetles come to the area of the
trap than are actually caught and killed, so damage to susceptible plants
near or adjacent to traps can be great. The notes that Danitol and Sevin
work best against these beetles. Imidan, malathion and Marlate
(methoxychlor) are moderately effective.

Try Sevin next time.
