Insects are a crucial part of the ecosystem, and thankfully, most of the species living in your trees are harmless. However, certain caterpillars, aphids, carpenter ants, and some types of beetles can damage trees and leave them more vulnerable to disease. Although you can't—and wouldn't want to—eliminate all insects on your property, this advice from a tree service can help you protect your landscaping from a pest infestation. 

How to Keep Harmful Pests Away from Trees 

1. Mulch Correctly

Covering tree roots with a layer of organic mulch helps maintain moisture in the soil and provides the tree with vital nutrients. However, if the mulch is too thick or touches the tree trunk, it may do more harm than good. A so-called "mulch volcano," where the mulch is piled up around the base of the truck, can attract harmful insects. 

It also causes moisture to linger around the trunk, which can contribute to rot and decay, attracting pests and stunting the tree's growth. Tree services recommend spreading a 2-3 inch layer of organic mulch around the tree, leaving a few inches of space between the trunk and the mulch for the most benefit. 

2. Attract Beneficial Insects 

Since not all bugs are bad, fill your landscape with plants that attract beneficial insects and pollinators like dragonflies, ladybugs, and bees. These not only help support healthy plants, but they can protect trees from harmful bugs as well. Ladybugs, for example, eliminate aphids that will eat all the leaves. 

3. Invest in Tree Trimming 

Keeping trees as healthy as possible reduces the risk of insect infestations. This includes professional pruning by a tree service. Trimming trees at the right time for the species can make a big difference to its overall health. Some, like oak trees, for instance, should only be trimmed during the dormant period, while doing so in the growing season can attract disease-causing beetles. If you aren't sure what is the best time of year for landscaping maintenance, consult with an arborist. 

4. Use Natural Oils 

Chemical pesticides can harm beneficial insects as well as harmful ones. However, if you feel it is necessary, spray the pests with horticultural oils. These are typically refined mineral, vegetable, or essential oils diluted with water. Focus your efforts on the bugs rather than the trees if possible.
