The better rat trap. Eco safe, ready to use, best quality glue. Keep out of reach from kids and pets. Trubble Gum is a unique rat trap that looks like a book and opens like one. Once opened, you can find inside two special glue surfaces separated by spacers to stop them from sticking to each other. These surfaces are extremely sticky. Rats and Mice are creatures of habit – they tend to follow a fixed route along walls and corners. And they don’t walk – they scamper.
