I didn’t know about them. They might be worth a try if the oil fails. Thanks.

Ok, one month into the test on the three rather hardy plants.

A very good result. The mealy bug type critters have all vanished. The hard scale is still there - I think it’s dead though.

Plant health visibly improved.

I’ll give them another shot to deal with the next generation.
