One of the things gardeners fear the most is their plants succumbing to a pest infestation. Although hydroponic systems are usually set up inside, they aren’t immune to the threat of pests that regular outdoor gardens face.


Having to deal with hydroponic plant pests is par for the course. Fortunately, there are measures you can put in place to protect your hydroponic system. The first step is to be aware of the signs of pests by carefully monitoring your hydroponic system at all times.


  • How to identify common pests

Identifying plant pests is the first step in taking control and ensuring that the problem does not escalate. Here’s what to look out for.


  • Spider mites

These are the most common pests, and they can do serious harm to your plants. To diagnose a spider mite infestation, look for any spider-like webbing or test for spider mite blood, which is easily done by wiping the underside of leaves with a tissue. The tissue will appear to have lots of little black specks if spider mites are present.


  • Thrips

Thrips are not as easy to spot as spider mites, but the damage they leave behind is easy to see. Examine the leaves of your plants for small, metallic-looking, black spots. Another visual clue will be leaves turning brown and drying up. Thrips not only feed on leaves but tend to consume flowers too, which can seriously affect your harvest.


  • Fungus gnats

Fungus gnats are a common indoor plant pest that thrive on moisture and humidity. These little bugs can be seen flying around your house or sitting on the soil of your hydroponic plants.


  • White fly

These small moth like creatures feed on the leaf, stem and bud sap of plants and vegetables. You are likely to discover these pests when you water your plants as they will start flying around. Your plant’s leaves will start to curl up and wilt and they can also spread disease to other nearby plants.


  • Aphids

Aphids are found mostly around the stems of plants. They suck the sap from leaves, and in so doing, extracts essential amino acids required for plant growth. Warning signs of an aphid infestation include prematurely yellowing leaves, distorted shoots and a black sooty mould fungus.
