Rodent Control in Fort Myers: Signs, Prevention, and Treatment

Scratching sounds in the attic at 3 a.m. Gnaw marks on the edge of a cabinet. Droppings along the garage wall. If you have noticed any of these signs in your Fort Myers home, you likely have a rodent problem. And in Southwest Florida, that almost always means roof rats.

Roof rats (Rattus rattus) are the dominant rodent pest in Lee County. They are agile climbers that enter homes through gaps as small as a quarter and set up nesting sites in attics, wall voids, and garage ceilings. Traps alone will not fix the problem because new rats will use the same entry points. Here is what actually works.

Warning Signs of Rodent Activity

Rodents are nocturnal, so you will hear them before you see them. The most common signs Fort Myers homeowners report:

• Scratching or scurrying in the attic or walls, usually starting after sunset. Roof rats are most active between midnight and dawn.
• Droppings: Roof rat droppings are about half an inch long, dark, and spindle-shaped. You will find them along walls, in the garage, near pet food, or in the attic insulation.
• Gnaw marks: Rats chew constantly to keep their teeth filed. Look for gnaw marks on wood trim, electrical wiring, PVC pipes, and food packaging.
• Grease marks: Rats follow the same paths repeatedly. Their oily fur leaves dark smudge marks along walls and rafters at their travel routes.
• Fruit tree damage: If you have citrus, mango, or avocado trees, partially eaten fruit on the ground is a strong indicator of roof rat activity. Fort Myers properties with fruit trees have significantly higher rodent pressure.

Why Traps and Poison Are Not Enough

Traps catch individual rats. Rodenticide (poison) kills individual rats. Neither addresses the fundamental problem: the entry points that let them into your home.

A typical Fort Myers home has 10 to 20 potential rodent entry points: gaps where plumbing and electrical lines penetrate the roof or soffits, unsealed soffit returns, damaged attic vents, gaps under garage doors, and openings where the roof meets the fascia board. Trapping the rats inside while leaving these openings unsealed just creates a revolving door. New rats smell the scent trails left by previous occupants and follow them right in.

What Professional Rodent Exclusion Includes

A complete rodent control treatment has three phases:

1. Inspection: A thorough exterior and interior inspection to identify every entry point, nesting area, and travel route. This includes the roof line, soffit system, plumbing penetrations, gable vents, and foundation gaps. In the attic, we check for nesting material, droppings, gnaw damage to wiring, and contaminated insulation.
2. Exclusion (sealing): Every identified entry point is sealed with rodent-proof materials: galvanized steel mesh, metal flashing, expanding foam backed by steel wool, or hardware cloth. This is the most important step and the one that DIY and poison-only approaches miss entirely.
3. Trapping and removal: With entry points sealed, the remaining rats inside are trapped using snap traps or live traps placed along their travel routes. Trapping typically takes 1 to 2 weeks. We check traps every 48 to 72 hours until activity stops.

Health Risks of Rodent Infestations

Beyond property damage (chewed wiring is a fire hazard), rodent infestations create real health concerns:

• Airborne contamination: Rodent droppings and urine in the attic dry out and become airborne particles that enter your HVAC system. This is a particular concern in Florida homes where the air handler is located in the attic.
• Leptospirosis: Transmitted through rodent urine, this bacterial infection is present in Florida and can cause serious illness in both humans and pets.
• Parasites: Rats carry fleas, ticks, and mites that can transfer to pets and humans once the rats are inside the home.

Prevention After Treatment

Once your home is sealed and cleared, these habits keep rodents from returning:

• Pick up fallen fruit daily if you have citrus, mango, or avocado trees.
• Keep palm trees trimmed so fronds do not touch the roof or provide a highway to the soffit.
• Store pet food and birdseed in sealed metal or heavy plastic containers, never in bags on the garage floor.
• Keep garbage can lids secure. Rats can chew through thin plastic lids.
• Trim vegetation at least 3 feet away from the exterior walls and roof line.
