Fascinating Fact:
Leaf miners are larvae that feed inside leaves, leaving winding pale trails. Damaged leaves can be removed to reduce the next generation.
Garden pests are animals that damage plants by chewing leaves, sucking sap, boring into stems, or attacking roots. Some, like aphids, multiply quickly and cause soft new growth to twist and weaken. Others, such as slugs and snails, create ragged holes, especially on young plants. Pests are often worse when plants are stressed by drought, poor soil, or overcrowding, so good watering, feeding, and spacing can make a big difference. A calm approach works best: identify the pest, remove what you can by hand, encourage natural predators, and only use controls that target the problem rather than everything in the garden.
Key Terms
- Pest: An animal that damages garden plants, for example by eating leaves or sucking sap.
- Infestation: When a pest becomes very common on a plant or in an area and starts causing noticeable harm.
- Targeted control: A method that focuses on the specific pest, such as hand-picking or using barriers, instead of affecting lots of wildlife.
Frequently Asked Questions (Click to see answers)
How do I tell if my plant has pests or a disease?
Pests often leave bite marks, holes, sticky residue, or visible insects, while disease is more likely to cause spots, mould, rot, or spreading patches without obvious chewing.
What is the safest way to get rid of aphids on plants?
You can squash aphids by hand, wash them off with a strong spray of water, or remove heavily affected shoots. Encouraging ladybirds and hoverflies also helps reduce numbers.
Why do slugs and snails attack seedlings at night?
Slugs and snails avoid dry conditions and bright light, so they feed at night or in damp weather. Seedlings are soft and easy to eat, so they are a common target.
