Major Garden Pest Insects

These insects are potentially major economic pests in gardens and yards. Monitor their numbers and your plant health. An increase in occurrence merits management for a healthy garden or yard. Before using chemical treatments, try some basic IPM strategies first. Discover where they come from, how to physically modify the environment, how to change your landscaping strategies, and, finally, limit chemical treatments to the area of concern. In major outbreaks, effective pest management may require community or neighborhood cooperation.
