Question: 38-1816
We have been told to wait for the leaves on our trees to mature before spraying against winter moths. Will they come from the woods every year? Cele, Warwick, RI

Mort's Answer:
Unfortunately, they will revisit every year and you will have to apply each year. You should never apply any pesticide when the leaves are just sprouting. You could severely burn them. Oil sprays can be applied for larvae prior to bud swell at 65 degrees. That has to be timed. Chemicals like pyrethrins are effective. It is impossible to spray all the woods and get control of this constant hazard, so you need to brace for an annual event.

Question: 1343-315
What can I use to get rid of these winter moths? Jeanne, Cumberland, RI

Mort's Answer:
You can apply a dormant oil when the temperature is over 45 degrees and under 65. Neem oil can be used at any temp. Come spring you can reapply the oil. Follow up the oil with pyrethrin to get the caterpillars before they pupate. You are too late to get the eggs that are on the branches now but you can still reign havoc when they hatch. Malathion is more powerful but is not organic and is hard to find.
