This year the Japanese beetle situation in my backyard here in SE PA is simply
dire - I have just disposed of the nine's bag, which probably gets the total
close to 12-15 pounds of bugs so far, and they keep coming! The usual amount is
perhaps 3-4 bags a season, and usually I don't dispose of them because they are
overflowing like this year, only because they start smelling awful. This year
I've also sprayed heavily, so the amount of bugs killed is staggering, yet they
It just so happened that I put the first two traps up maybe a week in advance of
actually seeing the first bug. This got me thinking that perhaps I have brought
this on myself by attracting the first bugs by the lure of the traps? And then
the consequent waves of bugs are just attracted by the previous ones? Has anyone
seen use of Japanese beetle traps to actually increase the amount of bugs?
I should add that I don't really have a place to put them 30 feet away from the
yard, like the description on the trap calls for, I have some oak trees about
10 feet or so from the property line, and that's the farthest I can put the
traps. Regardless, the leaves are destroyed in close proximity to the traps as
well as some 30-40 ft away.
So, what's the word on usefulness of the traps in the gardening community?
