Why Finding Broccoli Spider Mites is an Issue
- Size: Broccoli Spider Mites are extremely tiny, often less than 1mm in size, making them difficult to see with the naked eye.
- Habitat: They often live on the underside of leaves, which adds to the difficulty of spotting them. Also, as they prefer hot and dry conditions, they may not be obvious in cooler, more humid environments.
- Fast reproduction: Spider mites reproduce quickly, so even a small infestation can become a large problem in a short amount of time.
- Damage detection: The damage they cause can sometimes be mistaken for other issues. Spider mites feed by piercing plant cells to feed, which often causes a stippled or mottled appearance on the leaves. This type of damage can look similar to nutrient deficiencies or other pest damage, leading to incorrect diagnosis.
- Pesticide resistance: Broccoli Spider Mites can develop resistance to pesticides, especially if the same product is used repeatedly. This resistance can make it more difficult to control an infestation once it has started.
- Infestation spread: Spider mites can spread rapidly from plant to plant, especially when plants are close together as in a commercial broccoli field. This rapid spread can make it challenging to control an outbreak once it begins.

How to Identify Broccoli Spider Mites Problem
1. Visual Examination
Start with a visual examination of the plants. Look for changes in leaf color, particularly a stippled or mottled appearance, often yellow or white.
As Broccoli Spider Mites are very tiny, they might not be immediately noticeable, but the damage they cause is often visible. If you see discoloration, use a magnifying glass to inspect the leaves closely. You should look for tiny, moving specks and possibly fine webbing.
2. Shake Test
A common method for detecting spider mites is the shake test. Hold a piece of white paper under a leaf and then shake or tap the leaf. If there are spider mites, some will fall onto the paper and be visible as tiny, moving dots.
Spider mites get their name from their tendency to produce fine silk webbing, particularly when they’re present in large numbers. If you see webbing on your broccoli plants, it’s a strong sign of a spider mite infestation.
4. Predator Presence
The presence of certain insects like ladybugs, lacewing larvae, or minute pirate bugs can indicate a Broccoli Spider Mites infestation as these are natural predators of spider mites. These beneficial insects can help control mite populations, but their presence might also indicate an existing mite problem.

How to Solve Broccoli Spider Mites Problems
1. Introducing Predators
Introducing natural predators is a safe and effective way to control Broccoli Spider Mites. Predator mites, such as Phytoseiulus persimilis and Neoseiulus californicus, along with insects like lady beetles and lacewing larvae, can help manage an infestation.
These predators eat spider mites and can provide ongoing control.

2. Use of Miticides
Specific miticides can be used that target spider mites. However, it’s important to rotate products as spider mites can develop resistance to miticides if the same product is used repeatedly. Always follow the manufacturer’s instructions when using these products.
3. Water the Plant Right
Modify your watering practices. Spider mites thrive in hot, dry conditions, so overhead watering can help create an environment that’s less hospitable to them.
However, do this early in the day so that the leaves can dry out before night, to prevent conditions favorable for fungal diseases.

4. Proper Sanitation
Keep the area around your broccoli plants clean. Remove plant debris and keep weeds under control, as they can harbor spider mites.
If a plant is heavily infested, it might be best to remove and dispose of it to prevent the mites from spreading.
5. Diatomaceous Earth
Diatomaceous earth is a non-toxic powder made up of crushed fossilized algae (diatoms) that can be used to deter spider mites. The sharp edges of the powder cut and dehydrate Broccoli Spider Mites. It can be sprinkled around the base of the plants or mixed with water and sprayed on the leaves. However, be cautious as it can also affect beneficial insects.
6. Insecticidal Soap
This is a safer option that can be effective against Broccoli Spider Mites. They work by smothering the mites. However, these soaps have to come in contact with the mites to be effective, so thorough coverage, especially on the underside of leaves, is important.
