Friend or Foe?

Keep your friends close and your enemies closer.

Just make sure you know who is friend or foe!

This praying mantis won't eat your plants, but dozens of other insects will. And not all of them will be so obvious.

Except for caterpillars and grasshoppers, most insects that feed on cannabis are much smaller than a praying mantis. Insects with piercing-sucking mouthparts are much more common, such as aphids, whitefly, thrips, and spider mites. 

Always carry a hand loupe and schedule time for scouting. Train new employees which insects to look for, and set up a monitoring program that involves sticky traps. 

Yellow sticky traps work better for spider mites, while thrips are more attracted to the color blue. 

Use both in your growing area and keep track of who you're catching, how often, and how many. This information will help you to make timely adjustments to your IPM program.
