No. If these critters appear on your property, it’s not due to new wood decking. Your garden or backyard has likely attracted rats because it features a food or water source for them. Check if your bird feeder spilt seeds and cover any rubbish bins. Rats are unlikely to make their nest and stay underneath wood decking. Should you need help with cleaning up your garden or need to get rid of pesky rats, you may book other Taskers for the job.
