There's a good reason why lady beetles, aka ladybugs, are prevalent this time of year: aphids.
Ladybugs, from the family Coccinellidae, are actually beetles with voracious appetites for those soft-bodied insects that suck plant juices.
Wherever there are aphids, you'll usually see ladybugs. It may take awhile for the ladybugs to find them, but find them they will.
