In this article, we will analyze the most common pests and how to deal with them, so you can keep your plants healthy and thriving.
Thrips: What are they and how to identify them?
Thrips are small, elongated insects with colors ranging from brown to pale yellow. They are known for their ability to feed on plant cells, leaving silver or streaky marks on the leaves. They may also leave dark excrement visible on the leaves or stems of the plant.
Common symptoms:
- Silver or golden spots on the leaves.
- Redness or discoloration of the leaves.
- Deformed or wrinkled leaves.
- Presence of small insects moving quickly.
How to control them: To treat thrips, it's essential to apply an appropriate insecticide, as well as manage humidity and temperature, since thrips prefer warm, dry environments. Yellow sticky traps can also be used to reduce their population.
Red Spider Mite: What is it and how to identify it?
The red spider mite is a tiny mite that feeds on plant sap. Although it is not an insect visible to the naked eye, its effects can be devastating if not controlled in time. Red spider mites typically leave a fine web on the plants and cause yellow or dry spots on the leaves.
Common symptoms:
- Yellow spots or discoloration on the leaves.
- Fine webs visible between the leaves and stems.
- Dry or brittle leaves.
- In severe cases, premature leaf drop.
How to control them: Control of red spider mites includes using specific miticides and increasing humidity, as red spider mites prefer dry environments. Using natural predators such as predatory mites can also be effective.
Caterpillars or Budworms: What are they and how to identify them?
Caterpillars or budworms are pests that primarily attack new shoots. They feed on young leaves and buds, which can stop plant growth or even kill the plant in severe cases.
Common symptoms:
- Leaves with bite marks or obvious damage.
- Visible caterpillars on the shoots or inside the buds.
- Damaged buds, appearing crushed or chewed.
How to control them: You can use biological products that eliminate the caterpillars without harming the plants, such as Bacillus thuringiensis. It's also helpful to regularly inspect your plants for the presence of caterpillars.
Aphids: What are they and how to identify them?
Aphids are small insects that feed on plant sap, sucking it from the stems and leaves. They often leave a sticky trail (honeydew) that can attract black mold.
Common symptoms:
- Discolored or yellowed leaves.
- Presence of aphids on the stems, leaves, or flowers.
- Excretion of a sticky substance (honeydew) on the leaves.
- Black mold on the leaves due to honeydew.
How to control them: Aphids can be controlled with organic insecticides or by using natural predators like ladybugs. Plants can also be sprayed with soapy water or neem oil.
Soil Fungus Gnats: What are they and how to identify them?
Soil fungus gnats are pests commonly found in the soil where the plants are growing. The larvae of these flies feed on the roots, which can seriously affect plant growth.
Common symptoms:
- Small flies flying near the soil.
- Discolored or rotting roots.
- Yellowing or wilting leaves.
How to control them: You can control soil fungus gnats by applying diatomaceous earth or using yellow sticky traps to attract and trap the flies. It's also important not to overwater, as fungus gnats prefer humid environments.
Mealybug: What is it and how to identify it?
The mealybug is a white, cotton-like pest that can be found on the roots and stems of plants. Its cotton-like appearance makes it easily identifiable, and it is known for excreting a sticky substance that attracts ants.
Common symptoms:
- Presence of white or cottony spots on stems and leaves.
- Deformed or discolored leaves.
- Stunted growth or plant death.
How to control them: Neem oil is an effective solution for eliminating mealybugs. You can also clean the affected areas with a cotton swab soaked in isopropyl alcohol.
Micromite: What is it and how to identify it?
Micromites are a subcategory of mites that are even smaller than red spider mites. Though difficult to see, the damage they cause is evident.
Common symptoms:
- Damage similar to that caused by red spider mites.
- Leaves with yellow or dry spots.
- Fine and thin webs.
How to control them: Micromite control can be done with miticides and by increasing humidity in the environment.
Leaf Miner: What is it and how to identify it?
The leaf miner is a small pest that lays its eggs inside the leaves, where the larvae feed on the internal tissue, creating visible tunnels within the leaves.
Common symptoms:
- Clear tunnels or lines inside the leaves.
- Leaves with discolored spots or areas.
- Dry or wilting leaves.
How to control them: It is recommended to use specific insecticides for leaf miners and remove infected leaves.
Whitefly: What is it and how to identify it?
The whitefly is another common pest that feeds on plant sap and can cause severe damage if not controlled in time.
Common symptoms:
- Presence of small white flies flying near the plants.
- Yellow or spotted leaves.
- Excretion of honeydew that attracts black mold.
How to control them: Yellow sticky traps can be used to reduce the whitefly population, as well as organic insecticides.
Snails and Slugs: What are they and how to identify them?
Snails and slugs are known for their ability to devour leaves and stems, especially during the night.
Common symptoms
- Leaves with chewed edges or visible holes.
- Slime trails visible around the plants.
How to control them: It's recommended to install physical barriers and use crushed eggshells to prevent their appearance. You can also use specific baits for snails and slugs.
