Signs You Have Mice in Your House and What Homeowners Should Do
Noticing droppings, scratching sounds, or gnaw marks? Call Titan Pest and Wildlife Solutions at (314) 720-8857 for a free on-site inspection.
If you suspect mice in your St. Louis home, you are not alone. Mice look for warmth, food, and shelter year-round, and older homes across the area often offer them plenty of entry points. The good news is that mice leave clear evidence behind. Knowing what to look for helps you act early, before a few mice become a much bigger problem.
We had a huge moth infestation that was traced to a pile of rolled up rugs in the basement. The team from Titan was fantastic. They treated the rugs twice, and sorted those that could be salvaged from those that could not. The team was careful, efficient, and very responsive to questions. They solved the problem.
Dennis was at the house right on time! He was very knowledgeable and thorough. Answered all of my questions…and even toe rated our badly dog without issue! I would definitely recommend him and the company!
I had a dead animal under my front stoop. J was able to respond to my call the first thing next day. He found the animal cleared the void out and disinfected the area. J is very professional and a genuine nice guy. He would be the one that I call next time.
After meeting Brandyn, and talking with him about an uninvited guest (racoon) in my attic...I was convinced that I made right call. Brandyn was very personable and patient. He answered all of my questions and concerns thoroughly with a very pleasant and professional demeanor. Brandyn came out to the house as much needed to help put my mind at ease and ensure the problem was solved. Titan Pest Solution overall was a pleasure to do business with. I would definitely highly recommend.
Brandyn and his team came out within 12 hours of calling to help us with an insect issue. Brandyn diagnosed the problem and went into details on why the issue occurred. He is extremely knowledgeable in his field of expertise and goes the extra mile to help his clients understand any and all bug, insect, and wildlife concerns in the areas around the house.
He returned later in the week to start the first part of the treatment plan. Titan Pest and Wildlfie is a great company and affordable company. I would highly recommend them
Reasonable price
Brandyn has been an incredible help from the start! I had reached out with a concern of Birds in my vents and they were cleared out and had caps added within 48 hours. It’s refreshing to work with people who are responsive and do a great job!
Dennis came this afternoon and was very professional. He was very thorough and friendly. He answered all my questions and concerns. He sprayed in areas that definitely needed attention. He also explained to me about my garbage disposal and drain and treated those areas. I always feel confident after you all come out to treat my place that the bugs will not come back.
Response from the owner:Hi, Staci. We are thrilled to learn that you had a positive experience with us!
Brandyn and Rusty were amazing! Super professional, on time, explained everything to me and how they would treat and fix the problems. We are super happy with everything from Titan and very glad after having other pest services that we chose them! Thank you!
We had birds in our vent and called Titan Pest Control and Wildlife Solutions for a free consultation. They removed two birds nest from the vents, disinfected the two vents and installed three vent covers over the three exhaust vents. They also treated a wasp nest for free! They were quick, professional and affordable! We decided to move forward with them for our monthly pest service!
I had a great experience with Titan Pest Control! They came out quickly and took care of a raccoon issue that had been causing us a lot of stress. The technician was professional, knowledgeable, and explained the process every step of the way. They made sure the animal was removed safely and gave us peace of mind.
I will say that the service was pricier than I expected, but the quality of the work, responsiveness, and professionalism made it worth the investment. If you’re dealing with a wildlife issue and want reliable service, I’d definitely recommend Titan Pest Control. They turned a stressful situation into a smooth experience.
Brandon did an excellent job at one one of our properties this morning. He was extremely courteous and knowledgeable with us (over the phone) and our tenants (in person). Definitely recommend!
Very courteous gentleman. Knowledgeable, professional and respectful. I appreciate their service.
1. Droppings
Mouse droppings are the most reliable sign of activity. They are small, dark, and shaped like grains of rice, usually about a quarter inch long. Check kitchen cabinets, pantry shelves, under the sink, along baseboards, and inside drawers. Fresh droppings are dark and soft, while older ones turn gray and crumbly. Finding them in multiple rooms often means the activity is more widespread than it first appears.
2. Scratching and Scurrying Sounds
Mice are most active at night. Many homeowners first notice light scratching, scurrying, or gnawing sounds in walls, ceilings, or attics after dark. Heavier thumping sounds may point to a larger animal, such as a squirrel or raccoon. Because we handle both pest and wildlife issues, our inspection can tell you exactly what you are hearing.
3. Gnaw Marks
Mice chew constantly to keep their teeth worn down. Look for small gnaw marks on food packaging, baseboards, door corners, and stored boxes. Chewed electrical wiring is a particular concern in attics and basements, so it is worth taking gnawing evidence seriously.
4. Nests and Nesting Material
Mice build nests from shredded paper, insulation, fabric, and other soft materials. Common spots include the backs of cabinets, storage boxes, garages, and attic corners. A nest usually means mice have settled in rather than just passed through.
5. Grease Marks and Odors
Mice travel the same routes along walls, leaving faint, greasy rub marks over time. A persistent musky or ammonia-like odor, especially in enclosed spaces, can also indicate ongoing activity.
What St. Louis Homeowners Should Do Next
Store food in sealed containers, keep floors and counters clean, and take out trash regularly. Snap traps can catch a few mice, but DIY methods rarely solve the underlying problem, because mice reproduce quickly and keep entering through gaps as small as a dime.
That is why professional treatment focuses on two things: removing the mice that are inside and sealing the entry points that let them in. Here is what to expect when you call us. We start with a free on-site inspection to confirm activity and locate entry points, then provide a clear estimate, and then carry out a treatment plan using proven methods applied per label directions. If your inspection turns up a wildlife issue instead, the same team handles it, with no need for a second vendor.

Frequently Asked Questions
Droppings in multiple rooms, daytime activity, or repeated sightings usually indicate more than one mouse. An on-site inspection is the most reliable way to gauge the extent of the activity.
Mice can contaminate food and surfaces with droppings and urine, and their gnawing can damage wiring. Addressing the problem promptly helps limit these risks.
It is unlikely. Once mice find food and shelter, they tend to stay and multiply. Early action is the most effective approach.
It depends on the level of activity and the number of entry points. We will walk you through the timeline after your inspection and estimate.
