Will The Home Made Insecticide Soap Kill Monarch Caterpillars ?

Question

Will the insecticide soap kill monarch caterpillars

Answer 1

Any kind of insecticidal soap will kill caterpillars and other soft bodied insects if you spray it directly on them. The soap is not residual, so once it dries on the plant or washes away, it won't harm them.
