Hi Russ –
Leaf eating caterpillars can be quite โa problem in โoutdoor gardenโsโ if not taken care of! Caterpillars are the larval stage of the insect order lepidoptera (moths and butterflies), butterfliesโ lay their eggsโ on host plantsโ, whichโ hatch when the eggโs environmental conditions are metโ — usually 2-3 weeks laterโ.
One of the most effective products for getting rid of caterpillars is Monterey B.t., when applied correctly. Mix 1 to 1-1/2 Tbsp per gallon of water and apply when worms or caterpillars are first noticed, then repeat at five to seven day intervals while they are active. Apply thoroughly to top and bottom foliageโ and reapply after heavy rains. Pyrethrin โsprays will also work well to control them.
One of our favorite pyrethrin products is Monterey Take Down, it โโcombines the fast knockdown of pyrethrin and the residual activity of canola oil. A natural alternative to Dursban, โTake Downโ works on a large number of insects both indoors and out. Kills ALL stages of insects, including eggs and breaks down quickly in the environment. Although pyrethrin can have harmful effects on beneficial insects.
Hope this helps!
