Winter Moth Control Program

Cape Cod Moth TreatmentCape Cod Moth Treatment

We use a two phased Organic Program…

Phase 1: Horticultural Oil (March before bud break) - It is applied to the entire tree and works by suffocation and can be effective on the eggs. While this will achieve only limited results, as the eggs are virtually everywhere, it is a good step to reduce the population.

Phase 2: B. t. k. or Spinosad (Bud Break – Late May) We strive to use B. t. k as our first choice and will use it exclusively for the first portion of the “application time window”, then switch to Spinosad as needed. Both offer good control when used within their limits

Horticultural Oil: A highly refined oil (mineral or vegetable based) mixed with water.

B.t.k (Bacillus thuringiensis kurstaki): This product is a bacterium specific to butterfly and moth larvae. It must be ingested to be effective. Once inside the gut it becomes toxic and is lethal to the caterpillar. Please note:

A: B.t.k. works best when the larvae are young
B: Does not harm the environment, the applicator or other beneficial insects when used as directed.
C: Caterpillars stop feeding almost immediately after ingesting B.t.k. and die in 1 – 3 days.

Spinosad: This product is derived from a bacterium which is subjected to a specific fermentation process. It works by both contact and ingestion.

A: Spinosad works well on caterpillars of all ages
B: Although considered fairly safe, it can be highly toxic to bees at the actual time of application. However after it has dried, its toxicity to foraging bees is highly reduced.

Although there are other insecticides that are available, we have chosen not to include them in our program due to increased toxicity. If, however, a more aggressive control is warranted, we can discuss these other options, but these are only considered for specific, highly valuable trees.
