Types of Bugs Commonly Found in Houseplant Soil

Bug Type Description Prevention
Fungus Gnats Tiny, fly-like pests. Allow the soil to dry between waterings.
Spider Mites Minuscule, spider-like arachnids. Increase humidity to deter mites.
Mealybugs White, cottony pests that suck the life out of plants. Prune affected parts and isolate plants.

The most common culprits include:

  • Fungus gnats: Tiny, fly-like pests.
  • Spider mites: Minuscule, spider-like arachnids.

Understanding the life cycle of these pests is crucial in combating them. For instance, fungus gnats have a life span of about four weeks, with females laying up to 300 eggs in the soil. These eggs then hatch into larvae, which feed on plant roots, causing significant damage.

Spider mites, on the other hand, reproduce rapidly in hot, dry conditions. In just a week, they can go from egg to adult, causing havoc all the way.

Signs That Your Houseplants Are Infested

Some tell-tale signs include:

  • Yellowing or browning of leaves.
  • Webbing on the plant, especially underneath the leaves.
  • Visible pests on the soil or plant.
