Never heard of the Red wine thing, however the most safest and natural Cockroach Trap....
A Cockroach trap consisting of a jar, Ground Coffee, and water, placed against a wall. The homemade trap is made from any glass jar containing used coffee grounds and water. Placing the mouth of the jar next to the wall, the roaches are able to crawl up the wall and into the jar, to drown, or at least never escape since they are unable to climb the glass walls. Apparently, only cockroaches are attracted to it. its easy, safe and organic.
For free-standing jars, wrap the outside of the jar with packing tape or similar to give the roaches something to grip onto to climb the jar.
Hope it works out well...
