Certain beneficial insects prey on nasty bugs that chew ornamental and edible garden plants.
The garden helpers you will want to attract:
Big eyed bug
Lady Beetles (ladybugs)
Syrphid flies (Hover flies)
Soldier bugs (Stink bugs)
Wasps (Ichenumonid, Braconid)
Set up birdbaths or shallow dishes of water here and there in the garden. Place sticks and rocks in the water so that insects have a place to perch while they drink. Change the water every two or three days so mosquitoes won’t breed.
To attract and maintain colonies of beneficial insects, minimize or avoid the use of chemicals in the garden.
