Does Yates Caterpillar Killer kill Spit Fire Caterpillars

Hi Alessio,

We would suggest that you use a contact insecticide called Yates Baythroid, Lawn Grub and Insecticide. This product is a fast acting contact synthetic pyrethroid with long lasting residual when applied at a low dose. The eggs of this sawfly are deposited in slits in the leaves. After hatching, the larvae remain together in a group on the branch. It is possible to prune off the branch and dispose of them but wear a pair of gloves and be careful when handling these creatures.
