Dose Dormant Spray Oil work on Bagworms over the Winter or only before breeding in the fall?

Will this sufficate the eggs of bagworms if I spray in early Fall?


The Dormant Spray Oil is actually not labeled for bagworms so we cannot recommend it be used for this pest.  The eggs are actually very protected by the bag they are layed it so no chemical will actually be able to kill them in this stage.  The best time to treat is in the Spring when the larvae hatch and before they form the bag as an adult.  Please take a moment to read over our Bagworm Control article.
