With all of the butterfly larvae we raise, it would never make sense for us to use pesticides or herbicides around the greenhouses. So how do we control pests that want to eat up our plants? Over the last few years we have experimented with various "biological" controls including parasitic wasps and praying mantis nymphs... we have decided we like the praying mantis the best! I honestly d0n't know if they do a better job, but they are way cool! The image to the right is a photo of the nymphs emerging from the egg sack.
