Do I need to worry about rats in my yard but not in my house?

• <div><p>Seeing a rat or two isn’t uncommon, especially in mild climates. That doesn’t mean they are actively a danger to your home. The problem is when you start seeing rats regularly in your yard, there’s a good chance they are also looking for ways to get into your house or other buildings. All they need is a small hole or gap, and they have a new place to nest -- which is bad news for you. Stay cautious if you start seeing rats in your yard all the time. </p></div>

Q: Will rodents leave on their own?

• <div><p>Like a rent-controlled apartment in New York City, rodents know a good thing when they see it. If they've found a cozy nest inside your home, they will set up camp and stay there, leaving only to forage for food and water. As long as they have a warm place to sleep, raise their young, and continue access to water and food, they're going to stick around.</p></div>

Q: Why am I finding mouse droppings but not seeing any mice?

• <div><p>Finding mouse droppings without seeing any mice is a common sign of an infestation because mice are nocturnal and skilled at hiding from humans. Droppings are often the first and most visible evidence of their presence. The location, quantity, and freshness of the droppings can help you determine where the mice are most active and how severe the infestation might be. Since mice are active at night and often travel through hidden pathways like inside walls, you may not see them directly. It's important to look for other signs of an infestation, such as gnaw marks, scratching sounds, or greasy trails along walls. If you find droppings, consider setting traps or contacting a professional exterminator to address the issue.</p></div>

Q: Can water bugs get into your plumbing?

• <div><p>It&rsquo;s unlikely true water bugs will get into your home plumbing system. You may find them in gutters, rain barrels, or open irrigation on your property. If there are bugs near your indoor pipes, leaky sinks, or other moist places, they are probably Oriental cockroaches. Consult a pest control professional to determine the pest hiding out in your plumbing system.</p></div>
