1. Unusual Spots or Discoloration on Leaves: Ever noticed freckle-like spots or a change in leaf color? This could mean that your plant is being feasted on by pests such as aphids, leaf miners, or scale insects.
2. Distorted or Misshapen Leaves: Ever seen a leaf that looks like it’s been through the wringer? If the leaves are curling, wilting, or just looking a bit off, this could mean that sap-sucking pests like spider mites and aphids are dining on your plant’s nutrients, causing the leaves to deform.
3. Damaged or Eaten Foliage: If the leaves, stems, or fruits of your plants look like they’ve been used as a snack, this could be a sign that pests have moved in. Larger pests like caterpillars, slugs, snails, or beetles are often to blame.
4. Wilting or Yellowing Plants: If your plant’s leaves suddenly start to wilt or turn yellow, pests could be at the root of the problem. Critters that feed on roots, such as nematodes or grubs, can stop the plant from getting the water and nutrients it needs, causing the leaves to wilt or change color. But remember, these symptoms can also mean that you’re overwatering your plant or not giving it the right nutrients.
5. Sticky Residue or Webbing on Plants: If your plants are looking a bit sticky, this could be the work of aphids or whiteflies, which leave behind a sugary substance known as honeydew. This can attract other insects and even cause a black sooty mold to grow on your plant. And if you spot thin, web-like structures on your plants, you could deal with spider mites.
6. Slow Growth or Poorly Thriving Plants: If your plant seems to be stuck in a growth rut despite getting the right amount of light, water, and nutrients, this could mean pests are sucking out the sap and leaving your plant undernourished.
