Best answer posted!
the sap beetle, a.k.a. picnic beetle, beer beetle, S.O.B beetle...
will attack and eat ANY over ripe or damaged fruit, even your sweetcorn.
Strawberries become bags of beetles, as do tomatoes...
Using ANYTHING to kill/prevent them, will kill the ones hit with the spray, and then their families will come to back them up.
This beetle is attracted to over ripe fruit, bread, vinegar, yeast, and they love your beer, just crack one open here in Minnesota, and it won't be long till you have them.
We are processing a bucket of Kraut at present, and we have the beetles on the screen door, wanting a taste.
This beetle is the carrier (vector) of the "Oak wilt disease" killing off much of the red oaks everywhere...
The method that Cynthia mentioned, id the Best, Set traps around your property...
Fill them with rotted fruit, beer, or water and yeast...they will come
and it will give you the pleasure of seeing a homemade device work...really well, I can dump 100-200 a day out of these traps...
I made a third compost heap way off in the corner of the property, and they LOVE it!
I use gallon milk jugs with a hole about 4 inches square cut in two sides, and about a cup of solution in the jug..
For those of you wanting to "Hybridize" the trap, add some sevin to the liquid IN THE JUG...and don't use sevin ON your crops!
