My polytunnel is infested with thousands, and I do mean thousands of caterpillars.
I have netted the doors and have only ever found one moth in the tunnel this year.
There are precious few butterflies in the garden.
I don't understand where they are all coming from. They have decimated the peas and killed the whole crop, the brasica as you would expect are taking a pounding and I have to check them over daily, each time removing dozens from each plant.
Just went out now to pick parsley & it's totaly covered from head to toe in the critters.
Can anyone suggest where them may be coming from & how I can stop them!
