Tree service mantra for pest control is regular inspection, targeted treatment and non-pesticide alternatives.

Spring is the peak time for insects to crawl, fly and bore through trees, according to the ISA Certified Arobrists at Giroud Tree and Lawn. As homeowners, the first instinct is usually to get out the heavy chemical artillery and spray the entire property to kill all the insects. Giroud Tree and Lawn provides a guide to Integrated Pest Management with tree service strategies to control harmful pests, protect beneficial insects and minimize chemical usage.

“The tree service mantra behind pest control today is integrated pest management (IPM),” says Lou Giroud, ISA Certified Arborist and President of Giroud Tree and Lawn. “Regular inspections by tree service professionals with expertise in IPM, targeted pesticide treatment and treatment alternatives are key for successful control:”

1.    Regular Inspections: In trees, like humans, prevention and early diagnosis is essential to good health. To successfully implement an Integrated Pest Management program, an ISA Certified Arborist should inspect trees several times a year to scout for insects and diseases and other problems that impact health and safety. Roots, trunk, branches, leaves and buds must be evaluated. If insects or disease are detected, the Arborist needs to determine the severity of the problem and what action, if any, is needed. A slight or benign problem may require no action other than closely monitoring the plant. If treatment is required, then the Arborist can recommend the best strategy with the least environmental impact.

2.    Targeted Pesticide Treatment: Never let anyone do a blanket spray of all plants on the property for insects. Treatments must be targeted only to the specific plants that have a problem. When an entire property is sprayed, several things happen. Beneficial insects that help the landscape are also killed. Trees not needing pesticides are also sprayed which means that more chemical than necessary is being utilized.

3.    Treatment Alternatives: Great advances have been made in tree service science. In the process, treatments for certain insects have been discovered that are actually more effective than spraying.    

  • Injections: There are two types of injections: trunk and soil. The choice depends upon the problem. The benefits of injections are numerous. The chemical stays in the tree much longer giving the tree more protection. It’s better for the environment because the material doesn’t have to be sprayed in the air. Injections also tend to be more effective because all parts of the plant are covered. Finally, the injection material is designed to stay in the root zone and leech down into the water table. Aphids, Soft Scales, most leaf eating caterpillars, Saw Flies, Lace Bugs and Leafminers are just a few of the pests being treated effectively through injections rather than spraying.
  • Pesticide Alternatives: Many traditional pesticides are being replaced with oils, soaps and natural pesticides that interfere with an insect’s respiratory or digestive systems. Beneficial insects such as ladybug beetles or nematodes may also be introduced to feed on harmful pests.
  • Mechanical Control: Some problems can be solved through mechanical means such as removing diseased areas from trunks or branches. Sometimes, cocoons, egg masses or the insects themselves may be removed by hand. When mechanical approaches won’t work then injections or spraying may be the best alternative.

4.    Prevention: Insects prey on vulnerable trees. The best way to prevent pest invasion is by keeping trees healthy:

  • Fertilize: Maintain proper nutrient levels with annual fertilizer treatments that are time released.
  • Enhance Growing Conditions: Improve soil consistency and structure through soil amendments and aeration.
  • Water: Maintain proper soil moisture by watering during dry periods.

Finally, timing is everything in controlling harmful pests. Treatments must be applied at the most vulnerable time in a pest’s life cycle. Insect life cycle reports combined with weather data enable researchers to forecast infestations, identify potential pest problems and pinpoint the best time each year to treat each insect.

Implementing a successful Integrated Pest Management program requires knowledge, careful monitoring and timely treatment by a tree service professional. However, it’s the best approach for trees, the environment and people.
