1 Confirm what you have before you buy anything
Rats and mice need different traps — getting this wrong wastes a week. I put a camera in my attic and knew within 24 hours. The Wyze Cam v3 runs on USB power, handles the 130-degree heat an unventilated Florida attic hits in summer, and the night vision is good enough to see droppings moving, which tells you exactly how many animals you're dealing with. Run an extension cord up through the attic hatch, point it at the area near the soffit vents, and check the app from your phone in the morning.
2 Set snap traps the night you confirm mice
The Victor Easy Set is the trap that actually works and has worked for 100 years. Set six of them along the wall joists — mice run edges, not open floor — baited with a pea-sized amount of peanut butter pressed into the trigger. In North Port's humidity, check and reset every 48 hours or the bait molds. Gloves on every time you handle a trap, dead mouse or not; hantavirus is rare in Florida but not worth testing.
3 Kill the population faster with a bait station
If snap traps are catching something every night for more than a week, you have a larger colony and need to hit them with rodenticide simultaneously. The Tomcat Bait Station with Refillable Blocks uses brodifacoum, which works in one feeding. Place stations near the eave vents and along the top plate — the highest-traffic zones. Florida's heat does not degrade the bait noticeably faster than up north, but check it monthly and replace dried-out blocks.
4 Seal every gap before you declare victory
This is the only step that makes the problem stay solved. Walk the outside of your house with a flashlight at dusk and mark every gap larger than a dime with painter's tape — mice need a quarter-inch, which is smaller than you think. The soffit-fascia joint, the pipe penetrations where FPL ran your meter conduit, and the dryer vent cap are the three spots North Port homes almost always fail. Stuff those gaps with copper mesh first, then seal over it with foam.
5 Foam over the mesh to weatherproof the seal
Copper mesh stops the chewing but lets in water, insects, and the humid North Port air that slowly destroys your insulation. Cover every mesh patch with Great Stuff Pest Block foam — it has capsaicin added, which discourages gnawing at the foam itself. This also helps your FPL bill: sealing attic penetrations is one of the five things Florida Power and Light's own efficiency checklist recommends before adding insulation.
6 Replace contaminated insulation if you see dark staining
Mouse urine fluoresces under UV light, and if your attic insulation is dotted with glowing patches, the smell will pull new mice in through any gap you missed — for years. Contaminated blown-in insulation in a standard North Port ranch runs about 800 to 1,200 square feet; a professional crew charges $1.50 to $3.00 per square foot to remove and replace it, or roughly $1,200 to $3,600. I checked mine with a $15 UV flashlight before deciding whether to DIY the replacement, which is a weekend job if you rent a blower from Home Depot.
Mice are a $10 problem until you ignore them, and then they're a $3,000 problem.
