Use Barrier Glue to protect trees and plants from crawling insects including vine weevils and ants by applying Barrier Glue around stems of plants or the trunks of trees. It can be applied around pots, table legs etc where it forms a barrier crawling insects cannot cross. It should be re-applied as necessary. It is ideal for protecting pots from vine weevil. Use on trunks of trees to stop ants. Ants crawl up to 'milk' aphids for the honeydew that they produce and then protect the aphids from natural predators such as ladybirds and lacewing larvae. By stopping the ants you increase the effectiveness on these natural predators. Supplied with handy dispenser - like a big syringe for easy application.
