Squirrel Control in Missouri: A Complete Homeowner's Guide

squirrels may be entertaining in the backyard, but once they break into your attic, they become destructive pests. Their constant gnawing damages wood, insulation, and electrical wiring, creating both costly repairs and fire risks. In Missouri, two breeding seasons each year drive these rodents indoors, especially when seeking warm shelter for winter or a safe place to raise young.

Quick answer

In Missouri, squirrel control means dealing with eastern gray and fox squirrels, which are game animals. You can shoot or trap them without a permit if they are causing damage, but you must report the take within 24 hours. For safe removal, contact a licensed wildlife control operator.

Key Takeaways

  • โ†’squirrels can squeeze through 1.5-inch gaps; seal all openings with heavy-gauge steel mesh.
  • โ†’Two breeding seasons (late winter/spring and late summer/fall) drive attic invasions.
  • โ†’Professional removal with one-way doors is the standard humane method.
  • โ†’Gnawed wires create fire hazards; prompt action reduces risk.
  • โ†’Missouri has both gray and fox squirrels; eastern parts see more gray squirrel issues.
  • โ†’Research: Property managers can expect only modest appetite for squirrel reduction: 15.2% of metro-area residents reporting squirrels or chipmunks nearby wanted somewhat fewer, according to Puri and colleagues' 2022 survey (published 2024) of neighborhood attitudes, not of squirrels inside buildings.

The Problem

Missouri has two main tree squirrel species: the eastern gray squirrel and the fox squirrel. Both are adaptable and thrive in urban and suburban areas. They seek shelter in attics, especially during colder months, and can cause significant damage. Their constant gnawing on wood, wires, and insulation is a real problem; it can lead to electrical shorts and fires. Their droppings and nesting materials can contaminate insulation and create health risks. With two breeding seasons per year, squirrel populations can quickly grow, leading to repeated invasions if entry points are not sealed. Summer highs near 88F turn an unshaded Missouri attic into an oven, which is why a July litter often gets abandoned in the hottest week and found by smell rather than by sound, while winter lows near 23F and humidity around 69% keep the animals coming back to that same warm, soft insulation each fall.

Warning Signs

  • โ€ขScratching or scurrying sounds in the attic, especially at dawn and dusk.
  • โ€ขChewed holes in soffits, fascia, or roof edges (often 2โ€“3 inches wide).
  • โ€ขDroppings (similar to rat droppings but larger, about 3/8 inch long) in attic or along walls.
  • โ€ขNests made of leaves, twigs, and insulation in corners of attic or crawl spaces.
  • โ€ขGnaw marks on wood, wires, or plastic pipes.
  • โ€ขVisible squirrels entering via gaps under eaves, vents, or chimneys.
  • โ€ขUnusual pet behaviorโ€”dogs barking at ceilings or cats fixated on attic access points.

Risks of Waiting

  • โš Electrical fires from chewed wires are a real danger.
  • โš Structural damage from gnawing on wood and support beams.
  • โš Contamination of insulation with droppings and urine.
  • โš Attracting other pests like insects and rodents to the food source.
  • โš Increased difficulty and cost of removal as squirrels establish nests.
  • โš Potential for squirrel bites or scratches if you attempt to handle them.

Treatment Options

One-Way Exclusion Doors

$200โ€“$500

A one-way door is installed over the main entry point, allowing squirrels to exit but not re-enter. After all squirrels have left (usually 3โ€“7 days), the door is removed and the hole is permanently sealed. This is the industry standard for humane removal.

1โ€“2 weeks including monitoringBest: Active infestations with identified entry points and no dependent young.

Live Trapping and Relocation

$150โ€“$400 per squirrel

squirrels are trapped in baited cage traps and relocated to suitable habitat. In Missouri, relocation is legal but must be done on the same property or with landowner permission. This method is less efficient for large groups and may not solve the entry issue.

Several days to weeksBest: Small numbers of squirrels inside a structure or those that have bypassed one-way doors.

Exclusion and Repairs

$300โ€“$1,500

After removal, all potential entry points are sealed with heavy-gauge steel mesh, metal flashing, or caulk. This includes roof vents, soffits, fascia gaps, chimneys, and utility line entries. Exclusion is essential to prevent re-infestation.

1โ€“3 daysBest: Prevention after removal or as standalone service for at-risk homes.

Squirrel Species You'll Meet in Missouri

Missouri has two primary tree squirrels: the eastern gray squirrel and the fox squirrel. Eastern grays are agile climbers, often found in suburban neighborhoods, and have gray fur with white undersides. Fox squirrels are larger, with a reddish-brown coat and a bushy tail, preferring more open woodlands and parklands. Both species can cause similar damage to homes, but their behavior differs. Gray squirrels are more likely to invade attics in urban areas, while fox squirrels may be more common in rural settings. Flying squirrels, though less common, are nocturnal and may also take up residence in attics. Recognizing which species you're dealing with can help tailor your removal and prevention strategies, as different species may respond differently to exclusion methods.

A Month-by-Month Timeline for Missouri

Squirrel activity in Missouri peaks during two breeding seasons, resulting in higher attic intrusion risk. The first litter is born in late winter (February to March), so females seek warm, safe nesting sites in attics during the coldest months. The second litter arrives in mid-summer (June to July), when temperatures are high and attics may offer cooler shelter. In late fall, squirrels may also enter homes to escape cold snaps, but this is less predictable. To prevent infestations, inspect your home in early spring and late summer, sealing any potential entry points before the next breeding season. Regularly check for signs of chewing or scratching, especially after storms or when trees are trimmed, as squirrels may exploit new gaps.

What the First Visit from a Professional Looks Like

When you call a professional squirrel control service in Missouri, the first visit typically involves a thorough inspection. The technician will walk your property, looking for entry points, signs of activity, and potential nesting sites. They may use a ladder to inspect the roofline, fascia, and soffit. Inside, they'll check the attic for droppings, chewed wires, and insulation damage. Based on the findings, they'll recommend a removal plan, which often includes one-way doors or trapping. They'll also provide a quote for exclusion and repairs. A reputable company will explain the process, including how they'll handle any trapped squirrels in compliance with Missouri's wildlife regulations, and what you can expect in terms of follow-up visits.

What Affects the Price in Missouri Homes

The cost of squirrel removal in Missouri varies based on several factors. The size and age of your home matter; older homes often have more gaps and are harder to seal completely. The extent of damage also influences price, as repairing chewed wires or replacing insulation adds to the bill. Accessibility is another factor; if your roofline is difficult to reach, the job may take longer and cost more. The removal method chosen also affects price: one-way doors are often more expensive than trapping, but they're more humane and effective for certain situations. Finally, the time of year can impact cost, as demand for services may increase during breeding seasons. Get multiple quotes to ensure you're getting a fair price for the specific work needed.

Renters, Landlords, and Who Pays

If you're renting a home in Missouri and discover squirrels in the attic, it's important to understand your rights and responsibilities. In most cases, the landlord is responsible for maintaining the property and addressing pest infestations that affect habitability. You should notify your landlord in writing immediately, documenting the issue. The landlord may hire a professional to remove the squirrels and seal entry points. However, if the infestation is caused by your actions, such as leaving food out that attracts squirrels, you may be liable for the costs. Tenants should not attempt to remove squirrels themselves, as this can be dangerous and may violate the lease. Communicate clearly with your landlord to resolve the issue promptly.

Prevention for Older Missouri Homes

Many homes in Missouri, particularly in older neighborhoods in St. Louis and Kansas City, were built before 1980. These homes often have original wood soffits, fascia, and roofs that have deteriorated over time, creating gaps that squirrels can exploit. To prevent invasions, pay special attention to areas where different building materials meet, such as where the chimney meets the roof or where utility lines enter the house. Seal these gaps with sturdy materials like metal flashing or hardware cloth, as squirrels can easily chew through wood or plastic. Also, check attic vents and gable ends, replacing any damaged screens. Regular inspections, especially after storms, can help you catch and address issues before squirrels move in.

How to Compare Two Quotes from Wildlife Control Companies

When comparing quotes from squirrel control companies in Missouri, don't just look at the total price. Ask what services are included: Does the quote cover inspection, removal, exclusion, and repairs? Are there any guarantees or warranties? Check that the company is licensed and insured, and ask for references. Also, ask about their removal methods and whether they comply with Missouri's wildlife regulations. A lower quote might seem attractive, but if it doesn't include sealing entry points, you may face recurring problems. Compare the scope of work and ensure you're getting a full plan that addresses both removal and prevention.

When to Call a Professional

If you hear persistent scratching, see gnaw marks on wires, or suspect squirrels have nested in your attic, call a professional immediately. squirrels are fast breeders and can cause extensive damage in weeks. Additionally, if you attempt DIY exclusion and trap squirrels inside, they may die and create odor problems. independent pest-control providers in Missouri are trained in humane removal and know local regulations.

DIY vs Professional

DIY methods like sealing small holes or using repellents (e.g., predator urine, ultrasonic devices) may offer temporary relief but rarely solve infestations. squirrels are intelligent and persistent; they can gnaw through caulk or foam sealant. Professional exclusion uses heavy-gauge steel mesh and one-way doors that ensure all animals are out. For most homeowners, the cost of professional removal is worth the peace of mind and long-term results. However, if you have a single squirrel that entered via an open door or window, you can open an exit and let it leave on its own.

Local Context

Missouri's climateโ€”hot summers and cold wintersโ€”makes attics attractive shelter. In the northern part of the state, near Kansas City and St. Joseph, winters are colder, driving squirrels indoors earlier. Southern Missouri, including the Ozarks and Springfield, has milder winters but still sees two breeding peaks. The St. Louis metro area, with its older homes and abundant mature trees, reports high squirrel intrusion rates. Columbia and Jefferson City see similar issues. In rural areas, fox squirrels are more common, but they behave similarly to gray squirrels regarding home invasions. Regardless of location, the key is to seal entry points before breeding seasons. For city-specific help, residents can call 1-888-546-7983 for a inspection terms that vary by provider tailored to their area.

Prevention Tips

  • โœ“Trim tree branches that overhang your roof to at least 10 feet away.
  • โœ“Install metal tree collars around trunks to prevent climbing.
  • โœ“Seal all gaps and holes in your roofline, fascia, and soffit with metal flashing or hardware cloth.
  • โœ“Repair any loose or missing shingles.
  • โœ“Cap chimneys with a sturdy cover.
  • โœ“Keep attics clean and free of potential nesting materials.
  • โœ“Install motion-activated lights or sprinklers to deter squirrels.
  • โœ“Feed pets indoors and avoid leaving birdseed or other food sources outside.

Frequently Asked Questions

How do I know if squirrels are in my attic vs. other animals?
squirrels are active during daylight, so scratching or running sounds at dawn and dusk indicate squirrels. Noises at night are more likely from raccoons or rats. Squirrel droppings are oval and about 3/8 inch long, similar to rat droppings but more rounded.
Can I use poison to kill squirrels in my attic?
No. Poison is inhumane and illegal for squirrel control in many areas, including Missouri. Poisoned squirrels may die in walls or attics, causing odor and attracting flies. Secondary poisoning can also harm pets or wildlife that eat the carcass. Always use humane exclusion methods.
How much does professional squirrel removal cost in Missouri?
Expect to pay $250โ€“$500 for removal, and $250โ€“$1,500 for exclusion and repairs. The total depends on the number of entry points and extent of damage. Most companies offer inspection terms that vary by provider. Call 1-888-546-7983 for a quote.
Will my homeowner's insurance cover squirrel damage?
Many policies exclude pest damage, including squirrels, because it is considered a maintenance issue. However, if squirrels chew wiring and cause a fire, the fire damage may be covered. Check your policy and consider a separate endorsement for wildlife damage.
How long does it take for one-way doors to remove all squirrels?
Typically 3โ€“7 days, but it can take up to two weeks if there are many squirrels or if they are reluctant to leave. Professionals monitor the door daily. After all squirrels are out, the hole is sealed permanently.
What should I do if I find baby squirrels in my attic?
Do not seal them in. Wait until they are old enough to leave (about 6โ€“8 weeks) or call a professional who can hand-remove them and reunite with the mother outside. Attempting to remove them yourself can separate mother and young, leading to death.
Do ultrasonic repellents work for squirrels?
There is no scientific evidence that ultrasonic devices effectively repel squirrels. squirrels quickly habituate to the sound, and it may not penetrate insulation. Physical exclusion is the only reliable prevention.
Can squirrels cause structural damage to my home?
Yes. Their constant gnawing can damage wooden beams, drywall, and plastic pipes. They also tear insulation for nesting, reducing energy efficiency. Over time, water leaks from damaged roof flashing can lead to rot.
Why does squirrel removal from a ceiling cost so much more?
Access. Fixr's January 2025 U.S. cost guide estimates removing squirrels from inside a ceiling at $750 to $1,500, against $300 to $600 for an attic, because the technician may have to cut into drywall to reach the animal and then patch it. These are publisher estimates, not observed customer bills, and local quotes vary. If you hear scratching between floors, call sooner rather than later; a dead animal in a ceiling adds odor and further cost.
