Rats commonly forage in a 50-meter radius and one colony may be dominating an entire building, making them controllable with a few well-chosen bait and trap placements.
Mice seldom establish territories that extend beyond 10 metres. If you find evidence of mice, draw an imaginary boundary 3 metres in each direction – this is the likely territory of a single mouse colony. Look here for entry points, feeding areas, and nest sites.
Mice hate change – moving things around, like pallets, boxes and shelves will shake up their environment and force them out to explore. This makes them easier to bait and trap. Therefore, an active stock rotation policy can be a very effective mouse control tool in warehouses and restaurant storage areas.
Rats can produce litters of five to eight pups every six weeks, and those pups will start breeding in just 12 short weeks.
Some palaeobiologists predict rats could evolve like dinosaurs did – growing larger and larger over time to outsize any remaining predators.
