Aphids are incredibly small hydroponic garden pests that are only 1/8 of an inch long. Aphids come in a huge variety of colors, including green, white, yellow, red, brown, and even black.

Aphids feed on plant sap, turning the leaves of your plant brown, wilting, and curling. New plant shoots may appear stunted or malformed. Their waste draws other pests, like ants, just like other suckers do. In order to safeguard their supply of sweet aphid waste, ants have been observed to “protect” aphid colonies.

Venomous spiders

The majority of the time, spiders pose no threat to a garden, but spider mites are not spiders. When you see their distinctive web, you frequently realize you have a spider mite problem. That web serves to shield the mite and its eggs rather than to capture prey.

The plant’s leaves become yellowed and eventually die as a result of mites feeding on them. They can harm the plant by creating a sticky web. If the infestations are limited to just one or two plants, it is simpler to remove the plants so that the mites don’t spread than it is to get rid of them using a product from the store.

Whiteflies are easy to spot when they are adults but more challenging to spot when they are young. On the underside of the plant’s leaves, they frequently hang out in groups.

In addition to sucking the sap from your plants, the whitefly’s droppings also attract disease and pests like ants, leaving your plants wilted and vulnerable to infection. Virus transmission from plant to plant has also been linked to whiteflies.


For a few reasons, thrips can be a challenging pest to find in hydroponic gardens. They are green, so they blend in well, and they hang out on the underside of plant leaves. Thrips are also fairly swift, and when they detect your presence, they will quickly jump or fly away.

Learn how to identify and eliminate thrips from your hydroponic garden!

Thrips often cause white or yellow spots on plants, which can give them the appearance of having a silvery sheen.
