We live in the woods and the neighbors have ponds.  We are pleased with the number of mosquitoes this bug zapper has killed. We purchased two 1/2 acre units so we could put them in different areas.  We put the Octenol in one and we don't see a difference in bugs killed. I guess the Lurex3 is the better one for the south.  May try it but so far pleased with zapper without attractant.
