Say that when they have eaten all your brassicas, I had a massive infestation of whitefly and that the only reason I used it, if i see just a couple then thats fine, but when its hundereds its time to take action as nature is obviously not coping with it
I don’t have any brassicas. It’s entirely up to you of course but I garden for pleasure not food and I love to see and hear all the wildlife which includes ladybirds 🐞 On the allotment I was growing cabbages which got covered with caterpillars I was advised to kill them but I decided I would rather have butterflies than cabbages and I left the caterpillars alone and don’t grow the cabbages any more. Each to their own but I would be aware that any insecticide may harm beneficial creatures.
I understand your sentiment there and I know that many people will have different opinions and may not agree with killing them, as I said i would only use it on large infestations as I grow my veg to eat
Also this insecticide only kills soft bodied insects as far as im aware, i use it and i still have ladybirds, spiders, flys, and other beneficial insects so as far as i know it does not harm them
I am not an expert but I think oil and detergent sprayed onto an insect would kill it. I do see your point if you rely on crops for food it’s probably a difficult decision to make.
also i only spray onto leave with the pest insect on, if ladybird larve are present i will remove them to other plants that are not being treated, i am not saying kill all bugs just control them if you have an infestation
I have never seen so many ladybird larvae as I have seen this year they have just about cleared all the greenfly and black fly I have had very little aphids on my broad beans so I must be doing some good.
