Best Organic Treatment for this Pest?

Hello,

I have a problem with a pest attacking my pea plants (Kelvedon Wonder), which are being grown in a planter on a small balcony.

I think I'll have to start again with fresh soil, but I'd like to prevent them attacking again.

I'm fairly new to gardening, so perhaps someone could help me identify the pest and suggest an organic prevention method?

Thanks!

 

Good evening GMS and welcome to the site. They are aphids and can be treated with a softsoap based insecticide available at your nearest garden centre.

 

Thanks for the reply. I'll try this on the next batch of plants.

Regards,

GMS
