Rodent Control & Removal Services in St. Louis, MO

Your Local Rat & Mice Exterminators

Serving St. Louis | St Charles | Belleville | Edwardsville | Champaign

Hearing scratching in the walls or finding droppings and gnaw marks can be a sign that rats or mice have entered your St. Louis home or business. Rodents can cause property damage and contaminate food, and problems can continue when they have access to the food, water, shelter, and openings they need to remain inside.

Bug Out provides professional rodent control and removal services in St. Louis, MO, for residential and commercial properties. Our trained technicians can inspect your property, determine where rodents are active and how they may be getting inside, remove existing rodents, and recommend exclusion and prevention measures to help address the problem and limit future access.

Common Rodents in St. Louis

Several types of rodents may be found in and around St. Louis properties. Common species include:

Signs You May Have a Rodent Problem

You do not always have to see a rat or mouse to know one is nearby. Rodents are often most active at night, and their activity can leave clues. Common signs include:

  • Droppings: Small, dark droppings may appear near food, cabinets, walls, storage areas, or other places rodents frequent.
  • Gnaw Marks: Rats and mice gnaw on wood, food packaging, insulation, wiring, and other materials.
  • Nesting Materials: Rodents may build nests in secluded areas from shredded paper, insulation, fabric, and other fibrous materials.
  • Scratching or Movement: Noises in walls, ceilings, attics, or other enclosed areas can indicate rodent activity.
  • Rub Marks: Rodents can leave dark or greasy marks along walls and other surfaces where they regularly travel.
  • Unusual Odors: A musky odor or unpleasant smell may develop where rodents are active or where a rodent has died.

Rodent Control and Removal

Removing rats and mice is only part of addressing a rodent problem. If rodents can continue accessing a property through gaps or other vulnerable areas, new activity may develop after the existing rodents are gone. Identifying those conditions is an important part of rodent control.

Bug Out begins with a property inspection to identify evidence of rodent activity and potential ways rodents may be getting inside. Depending on what we find, our technicians can use trapping, baiting, removal, and exclusion methods suited to the property.

Exterior bait stations may also be used when appropriate. With ongoing monitoring, we can check for continued rodent activity and determine whether additional control or prevention measures are needed.

Our Rodent Control Process

When you contact Bug Out for rat and mouse control in St. Louis, our technicians can take a comprehensive approach that addresses both existing activity and potential re-entry. Our process includes: 

  • Thorough Inspection: We inspect the property for signs of rats or mice, areas of activity, potential food and shelter sources, and openings that rodents may be using to enter. Mice can fit through remarkably small openings, making a detailed inspection an important part of effective exclusion.
  • Customized Treatment Plan: Every property is different. Based on our findings, we develop a rodent control plan suited to the type and extent of activity, the structure, and the conditions contributing to the problem.
  • Rodent Removal: Traps, baits, and other appropriate control methods may be used to address rats and mice that are already on the property. The specific approach depends on the location and circumstances of the infestation.
  • Rodent Exclusion: Removing rodents does not address the opening that allowed them inside. Exclusion focuses on identifying and sealing vulnerable areas so rats and mice have fewer opportunities to enter again.
  • Ongoing Monitoring and Prevention: For properties that need continued protection, ongoing service can help monitor rodent activity, inspect exterior bait stations when used, and identify conditions that could contribute to future problems.

Rodent Exclusion for St. Louis Homes

Trapping and baiting can address active rats and mice, but they do not necessarily address the openings that allowed them inside. Rodent exclusion focuses on identifying and sealing those vulnerable areas. Common measures may include:

  • Seal Foundation Openings: Close gaps and openings around the foundation and other areas where rodents may gain access.
  • Secure Roof and Soffit Areas: Seal vulnerable areas around soffits, roof returns, fascia, and other roofline components.
  • Protect Vents: Seal or screen appropriate foundation, gable, attic, and other exterior vents to help prevent rodent entry.
  • Close Utility Openings: Seal gaps around pipes, plumbing penetrations, and other utility access points.
  • Repair Garage Door Seals: Replace worn weather seals and install door sweeps where needed around garage and exterior doors.
  • Seal Siding and Exterior Gaps: Close openings around siding corners, J-trim, cracks, crevices, and other potential entry points.
  • Install Covers and Mesh: Add appropriate covers or mesh to vulnerable dryer, stove, gable, and attic vents where needed.

Bug Out also uses Flexi Armour™ materials for rodent and wildlife exclusion when appropriate. Addressing entry points along with existing rodent activity can help reduce the chance of rats and mice returning and limit access for other nuisance wildlife.

Have used this pest control service for several years. Very rarely have an insect problem, but when I do, Bug Out comes immediately and addresses the issue! They have helped with ground wasps, pantry moths, sink flies, pantry moths, field mice, and roaches as needed over several years. As my regular ongoing service, they are also great. Highly recommend.

Frequently Asked Questions About Rodent Control

Bug Out provides professional rat and mouse control in St. Louis. Below are answers to common questions about rodents and rodent infestations. If you have additional questions, contact us today.

Droppings, gnaw marks, nesting materials, scratching sounds, rub marks, and unusual odors can all indicate rodent activity. Seeing an actual rat or mouse is another obvious sign, but you may notice evidence of activity long before seeing the animal itself.

Yes. Mice can enter through surprisingly small openings. University of Missouri Extension recommends sealing openings larger than about one-quarter inch when mouse-proofing a structure. Rats can also gnaw and enlarge openings to gain access.

Trapping can remove rats and mice that are already present, but trapping alone does not necessarily address how rodents gained access to the property. Identifying and correcting entry points can be an important part of a longer-term rodent control strategy.

Rodent exclusion is the process of identifying vulnerable areas around a structure and sealing openings that rats and mice can use to enter. Depending on the property, exclusion may involve doors, vents, foundations, roof areas, siding, utility penetrations, and other potential access points.

Scratching or movement in walls can be a sign of rodents, although other animals can also make noises inside a structure. Look for additional signs such as droppings, gnaw marks, odors, or nesting materials. If you suspect rats or mice are inside, a professional inspection can help identify the source of the activity and potential entry points.

Yes. Bug Out provides commercial rodent control and exclusion services for businesses in St. Louis. Commercial programs can include removal, exclusion, monitoring, and ongoing prevention tailored to the property.
