Two-Spotted Spider Mite Infestation

Spider mites thrive in warm, dry conditions common for Capsicum annuum. They pierce plant cells to feed on sap, leaving behind fine silk webbing and causing stippling (tiny white dots) on the leaf surface.

Very Common

How to confirm: Hold a white piece of paper under a pepper leaf and tap it to see if tiny crawling specks fall onto the paper.

Tetranychus urticae (European Red Mite)

This specific mite species is highly prevalent in pepper greenhouses. As populations explode, the webbing becomes more dense, eventually covering entire clusters of leaves and causing them to yellow and drop.

Very Common

How to confirm: Examine the undersides of the leaves for tiny reddish or orange dots which indicate a heavy mite population.

2 Prune and dispose of heavily infested or yellowing leaves to prevent the webbing from spreading to healthy clusters.

3 Increase humidity around the plant and ensure good airflow, as spider mites thrive in hot, dry conditions.

High Humidity/Low Airflow leading to Secondary Mites

While not a direct cause, stagnant air around pepper foliage can create microclimates that allow mite webbing to persist and accumulate. This often accompanies other physiological stresses like powdery mildew.

Common

How to confirm: Check for stagnant air pockets around the base of the plant and observe if the webbing is accompanied by white fungal spots.

2 Improve air circulation around the foliage by using a small fan or spacing plants further apart to prevent stagnant microclimates.

3 Monitor soil moisture levels to ensure the plant is not under additional physiological stress from overwatering.
