Pest Insect Control / Worms & Caterpillars

Javelin WG

Javelin WG Biological Bt Caterpillar Gypsy Moth Control

A Proven & Effective Organic Silver-Bullet for Armyworms Now Devastating Lawns.

Javelin WG is a biological insecticide specific for use against Lepidoptera larvae as listed on the label. Javelin WG must be eaten by the larvae to be effective. Since Javelin WG is most effective against small, newly hatched larvae, an early scouting program to determine early infestations is recommended. After consuming a lethal dose of Javelin WG, larvae stop eating within an hour, but may remain on the foliage until they die, usually within several days. Affected larvae move more slowly and tend to become shriveled and discolored before dying.
