Are these aphids on my Mexican Petunia?

Answered
This is my first year attempting any ”real” gardening, meaning I have committed more time and money into my backyard. That said, I am not familiar with common pests, nor how to deal with them. I hope the pictures help, but I’m not sure if these little bumps on my Mexican Petunia are aphids or not, but there are also black ants on the plant. I live in zone 9a.

    Hi T, Sure looks like aphids. Here's a link that may help: http://homeguides.sfgate.com/rid-aphids-petunias-48596.html

    Good luck!
  • Looks like aphids to me. Here is a link.


    If you are wanting to try other natural methods, try planting garlic, onions or chives in the same area with the petunias. Marigolds help too. I am in CA in a similar climate and for me it works well, plus I love to cook with onions, garlic and chives.

    They look like aphids to me. You can remove them from the plants by taking them to the shower and spraying them with water.

    For sure,when there are ants there are aphids.They look like a bad infestation,use can try horticultural oil,however at this point I would use a systemic granular insect killer

    You can buy ladybugs from organic garden suppliers. They are little orange/red beetles with black dots on their shells, and they devour aphids. A mixture of mild soapy water sprayed on them will suficate them also. I used to be an organic farmer, now retired.

    I had aphids on my tomato plants. I hosed the plant down really well and then planted a green onion by each tomato. No more aphids.

    I was going to suggest lady bugs also. Just be sure they are t lady beetles or the Asian lady bugs they are both orange w/black spots but you want the round ones not the long narrow ones. They will eat your lilies if you have any. Once you see the difference you will always be able to tell them apart, and which one you want and what ones you don’t. It just makes it sound difficult putting it into words but absolutely NOT!!

    They don't look like the aphids we get in New Zealand but you will not do any harm by mixing up some liquid dish washer liquid with water and spraying them until they are completely covered. Repeat a couple of times. The ants might be eating them but ants are not always welcome guests either.
