What will keep mice and rats away

What keeps mice and rats away is making your property hard to get into and not worth visiting. Seal gaps as small as a dime, remove food, water and clutter, keep trees and shrubs trimmed back from the house, and store trash tightly. Scents and gadgets on their own rarely work for long. 

Rodents are looking for three things: food, water and a safe place to nest. Take those away, indoors and outdoors, and they move on. 

Seal the entry points first 

Exclusion is the most important step. A mouse can squeeze through a gap about the size of a dime, roughly a quarter inch, and a rat through one about the size of a quarter. Check these common spots on Florida homes: 

• Gaps where AC lines, plumbing and cables enter block walls 

• Soffits, fascia boards and roof edges, where roof rats often get into attics 

• Gable vents and roof vents with damaged or missing screens 

• Gaps under garage doors and exterior doors 

• Torn lanai and pool cage screens near the house 

Fill small holes with copper or steel mesh, then seal over it. Rodents chew through plain foam and caulk. Cover vents with sturdy metal hardware cloth, and add door sweeps and garage door seals. 

Clean up the outside 

Your yard is where rodents decide whether your home is worth a closer look. 

• Declutter your property. Remove leftover construction materials, piles of yard debris and other clutter rodents can hide or nest in. 

• Keep your grass cut short and get rid of areas of tall grass and dense vegetation near the house. 

• Keep tree branches, palm fronds and vines trimmed several feet away from the roof and walls. 

• Pick up fallen citrus, mangoes and other fruit, and clean up spilled birdseed under feeders. 

• Store firewood off the ground and away from the house. 

• Make sure trash cans have tight lids, and regularly clean the area where they sit. 

• Bring pet food in at night instead of leaving it on the lanai. 

Take away food and water indoors 

• Keep your home or business clean and decluttered. 

• Wipe down food prep and dining surfaces after snacks and meals. 

• Sweep or vacuum floors in kitchens and dining areas regularly. 

• Wash dishes right after meals instead of leaving them in the sink overnight. 

• Store pantry items in airtight metal, glass or hard plastic containers. 

• Store pet food and birdseed in airtight containers too. 

• Repair leaky faucets and pipes under sinks. 

• Avoid storing cardboard boxes in the attic, shed or garage. Rodents shred cardboard for nesting. 

Do scents and ultrasonic devices work? 

Many products promise to repel rodents, but the evidence behind them is weak. 

• Peppermint oil and other scents may bother rodents for a short time, but the smell fades quickly and hungry rodents learn to ignore it. 

• Ultrasonic devices have shown limited results in studies. Rodents often get used to the sound, and it does not pass through walls or furniture. 

• Mothballs are a pesticide meant for sealed containers only. Using them in attics or living spaces is against the label and can be harmful to people and pets. 

• A cat may catch the odd mouse, but it will not solve an established problem. 

These can be small extras, but they never replace sealing and sanitation. 

When to call a professional 

If you notice the telltale signs of rodent activity, act quickly. Mice and rats breed fast, and a few can become an infestation in a short time. Look for: 

• Droppings in cabinets, drawers or the attic 

• Rub marks along walls and beams 

• Chewed holes in food bags 

• Scratching in the walls or scurrying sounds in the attic at night 

Our rodent control service finds where they are getting in, removes the rodents already inside and seals the openings so new ones cannot follow. Homes in Palm Harbor and Tarpon Springs with mature oaks and palms close to the roof are especially prone to roof rats. Curious why they are so hard to stop?

FAQ 

What smell do mice and rats hate? 

Strong scents such as peppermint oil, ammonia and vinegar are often said to repel rodents. They may work briefly, but the effect fades as the smell wears off, and rodents with a steady food source usually return. Sealing entry points and removing food is far more reliable than any scent. 

How small a hole can a mouse get through? 

A mouse can fit through a gap about a quarter inch wide, roughly the size of a dime. Rats need about half an inch, about the size of a quarter. If you can slide a pencil into a gap, assume a mouse can get through it, and seal it with metal mesh and sealant. 

Are mice and rats worse in winter in Florida? 

Rodents are active all year in Florida, but many homeowners notice more activity in fall and winter. Cooler nights send them looking for warm, sheltered spots like attics and garages. Late summer storms and yard work can also push them indoors. Sealing your home before the cooler months is a smart move.
