Judith from United States writes,

blue spruce caterpillars

Caterpillars have been dining on my blue spruce trees. They are now in cocoons. Is it too late to spray in September, or should I wait until next spring? Will Bifen do the trick?


Bifen IT is labeled for caterpillars and can be sprayed on blue spruce trees. It is not too late to spray as Bifen IT can be used all year around in non-extreme temperatures. When you are spraying, make sure to spray the top and underside of the leaves. You will use .25 fl. oz. per gallon of water. Please let us know if you have any additional questions.
