Peppermint castile soap for aphids?

11 years ago

Hi all,

After doing a little weeding in my balcony garden, I discovered I have aphids. I've always heard the old drop of dishsoap in a spray bottle trick.

#1 does it actually work?

#2 I use organic castile soap for nearly everything around the house but it's scented with peppermint oil. Is that safe for the plants or should I pick up a small bottle of traditional dishsoap? (Mostly flowers but a tomato plant and a couple other edibles as well)

#3 Would the addition of diatomaceous earth be harmful? I spray it regularly on the carpet to keep the dog free of fleas with very good luck.

Thanks in advance!
