Insecticide soil injections are an effective method for controlling many insect pests in Wixom, Michigan that harm landscape trees and shrub.

As opposed to foliar sprays, this technique involves injecting a systemic insecticide directly into the soil around the base of plants. The plant roots then absorb and distribute the product throughout the entire tree or shrub.

Benefits of Soil Injection

Insecticide soil injection offers several advantages for pest control:

1. Long-lasting protection: The treatment can provide extended control of various insects, reducing the need for multiple tree or shrub spray applications.

2. Broad pest control: This technique effectively controls a wide range of insects, such as:

• Adelgids

• Aphids

• Japanese beetles

• Emerald Ash Borer

• Scale insects

• Whiteflies

• Leaf beetles 

A side benefit of this manner of insect control is the flexibility of applying the treatment. Applications can be done from early spring through late fall, as long as the ground is not frozen. Additionally, the weather does not effect the application – treatments can be applied in windy or rainy weather. 

Application Details 

These treatments use a systemic insecticide that:

• Interferes with insect nerve impulses

• Stops pest feeding and reproduction

• Provides protection for extended time periods 

Environmental Considerations 

Insecticide soil injections are considered safe for the environment and can be applied in residential areas. Professionals recommend keeping the treated area moist for 7-10 days after application to ensure optimal absorption into the plant being treated. 

For Wixom residents, consulting our ISA Certified Arborists can determine the most appropriate timing for a soil injection based on specific landscape needs and target pest populations.
