  • Will Tanglefoot work on tent caterpillars?

    Created by Charlene Bew on

    When should I apply Tanglefoot to the base of a pecan tree to prevent tent caterpillars? I live in Virginia. How far up the tree do you put it, and how much will I need for a tree that is 12 feet in circumference? Thank you for your assistance

    Hi Charlene –

    Tanglefoot Pest Barrier can be used to restrict tent caterpillar movement and cut off access to feeding areas, but should not be applied to the base of trees since their eggs are laid on the higher branches. Caterpillars will emerge in March or April, depending on temperatures.

    We recommend Bacillus thuringiensis (Bt-k) to control caterpillars of all types. Apply Bt-k when worms or caterpillars are first noticed, then repeat at five (5) to seven (7) day intervals while they are active. Apply more frequently to control heavy infestations. Apply thoroughly to top and bottom of foliage. Reapply after heavy rains. BTK sprays do not harm honey bees or birds and are safe for use around pets and children.

    Hope it helps!
