Grease is the Word!
It looks like you want to halt the winter moth in it's tracks! We can help with this; we stock a glue band (don't worry about the description - glue and grease serve exactly the same purpose) which is designed to stop crawling insects – and the wingless female winter moth in particular – from reaching the tree’s branches where they lay eggs. You might see winter moths on a tree near you right now as it’s usually between October and December they make their bid for the top!
Best of luck!
