I have several swan plants that are covered in chrysalises, caterpillars and eggs. They are also covered in yellow aphids that seem to be causing the plants to start to wither and yellow. Is there a spray out there that will kill the aphids without harming the monarchs!

spray with a mild detergent mix, just be careful not to get too much on the caterpillers.Put a small squirt of dishwashing liquid into a 500ml sprayer - it works great with aphids

just squish 'em all - I don't like to risk my caterpillars, squishing works well :)
