How do I don’t really do much regular ‘gardening’ but I suffer from Crohn’s and have a few mint plants in the house for making teas with.. i’v just noticed a load of black eggs/poo on the underside of the leaves.. I managed to spot a greenfly and also this little bugger.. not sure what the pest is and how to solve it!
Looks like white fly but in any case I use insecticidal soap like Safers. No soap? Fill sink with soapy water and while holding the plant in the pot turn over and submerge in water. Do that once a week, works surprising well.
