Monkshood Aphid

Does anyone have any methods with dealing with a serious attack of the bright bluey green monkshood aphid?

Thanks

Hello peteandtrace

Just scanning the forum and came across your 'post' ; these are a serious aphid to deal with . It seems that agricultural chemicals (prohibitively expensive) would work , but accessing these may be difficult .

If my plants , at the expense of this years flowers , I would cut to ground and safely dispose of all foliage .

Then carefully (toxic roots) , separate and wash each stem and thoroughly sterilise with bleach . When dry , repot in containers and monitor their  progress in the Spring . It might be a good idea to sterilise the soil they have been growing in also .
Some might think it strange to talk about using bleach , but I have found that a strong solution is a very effective insecticide , as well as a germicide , viricide and killer of numerous bacteria . Cheaper too

Give it a go , what have you got to lose ?? Good luck !!
