Caterpillars, sawflies, leafminers, beetles, worms and other insect larvae attack various species of trees consuming their leaves. The damage caused by leaf-eating insects ranges, but in extreme circumstances defoliation may occur. Caterpillars, leafminers and leafrollers are the larvae of butterflies or moths.
Considering this, how do you keep bugs from eating your trees?
1. Aphids
- Wash plants with strong spray of water.
- Encourage native predators and parasites such as aphid midges, lacewings, and lady beetles.
- When feasible, cover plants with floating row covers.
- Apply hot-pepper or garlic repellent sprays.
- For severe problems, apply horticultural oil, insecticidal soap, or neem oil.

The surest way to identify Slugs and Snails is to visit your garden after dark with a flashlight. Look beneath leaves. These munchers eat irregular holes in leaves, attacking both older and new growth. Some types, known as Cutworms, chomp through seedling stems at soil level, causing plants to keel over.
Pine trees are susceptible to damage by over 20 different kinds of insects, including aphids, borers, caterpillars, mealybugs, and weevils. Look for signs of insects by examining needles, branches, and bark.
