1. Potentially Harmful to Plants
Many insect eggs found on leaves belong to species that can become pests. Once hatched, larvae may feed on plant tissue, causing damage to leaves, stems, and even fruits. Disturbing the eggs might lead to them dispersing, making them harder to control.
2. Some Insects Can Be Irritating or Toxic
While not all insect eggs are dangerous, some species lay eggs that hatch into larvae capable of secreting defensive toxins or irritating substances. Certain caterpillars and beetle larvae, for example, have bristles or secretions that can cause skin irritation, allergic reactions, or mild toxicity upon contact.
3. Risk of Spreading Infestations
If you unknowingly touch or move insect eggs, you could be spreading them to other healthy plants. Many insects, like stink bugs and aphids, reproduce rapidly, leading to widespread infestations that can be difficult to control in gardens.
4. Beneficial Insects May Be at Work
Not all insect eggs are harmful. Some belong to beneficial insects like lacewings or ladybugs, which are natural predators of garden pests like aphids and mites. Destroying these eggs could inadvertently reduce your garden’s natural pest control.
