Target garden pests with biological controls
Outdoor plants can be affected by pests above and below the soil. Some feed on roots, some damage leaves or stems, while others spend important stages of their life cycle in the soil.
Biological pest controls use selected beneficial organisms to target particular pests. Depending on the problem, the most suitable option may include nematodes or another targeted biological control.
Identification, timing and growing conditions can all affect which treatment is most suitable. Always check the individual Milbies product instructions before application.
