Yeah they're real cute -
until they decide they'd like to be your roommate!
Woe is me, what am I to do? Well, we as homeowners do not have to succumb to this mass exodus. There are a number of preventative measures that we can employ to deter this migration.
First: They gotta eat and drink - duh? Okay so this is easy, right? Uh, well, not quite. This is a bit harder than it sounds. Rodents are tricky and they are super-gnawers. We need to deny them what they want and that requires due diligence. Clean all areas under stoves, refrigerators and dishwashers. Keep counter tops clear of food. Do not leave glasses of water out overnight (see above picture, lol). Store dry food, pet food and birdseed in sealed containers. Clean pet bowls at night.
Second: Make your home undesirable as a shelter (for the rodents - not you). Again, this is easier said than done. What we need to do is to keep storage areas free of clutter. Rodent-Proof hard-to-access areas that tend to be neglected. And, store supplies or materials off the floor.
Third: Deny access. Make your home a fortress against the invaders. Metaphorically speaking, build your castle, build your moat, and raise the drawbridge. Seal up open crevices to your home such as near duct work.
Actually, maybe this is not the best use of time - these damn vermin can flatten themselves out to travel under cracks and crevices you would not believe possible!
My advice: make sure the first two measures are taken care of and there will be little reason that these pests will enter your humble, happy, well-organized, immaculately-cleaned abode.
