I invented something, too. All my neighbors adopted it.

Instead of the bags, which fill up in an hour, I just put a bucket of
soapy water under the attractor. As soon as the idiot beetles hit or
try to land on the attractor, they fall straight down into the bucket.

Then I toss the whole mess out into the field.

Those bags of dead beetles are the most horrible stench I've ever
smelled in my life....1000 times worse than diapers.
