For most homes, the best rat and mouse traps are plain snap traps, set in the right places. Enclosed snap traps are the better choice where kids or pets could reach them. Electronic traps work well for mice and are easy to empty. Glue boards and live traps have real drawbacks. Placement beats brand: the University of Kentucky's pest control material says to set snap traps perpendicular to the wall with the trigger end against the wall, because rodents run along edges.
Here is how each type compares and how to use it.
Snap traps
Snap traps are cheap, quick and effective. Use mouse-size traps for mice and larger rat traps for rats. Plastic snap traps with a wide trigger are easier to set than the old wooden ones and easier to clean.
Their downsides: they can hurt fingers and paws, and they need checking every day. In a Jacksonville attic in summer, a dead rat in a trap smells fast.
Enclosed and tunnel traps
These are snap traps inside a plastic box with an entry hole. Kids and pets can't reach the bar, and you don't see the catch. Many can be emptied without touching the rodent. They work well along garage walls, under sinks and anywhere people or pets pass. They cost more than open snap traps.

Battery-powered electronic traps deliver a shock when a rodent enters. They are enclosed, many have an indicator light when there is a catch, and they are easy to empty. They work best for mice and indoors, since they need to stay dry. Batteries need changing.
Live traps
Live traps catch the animal alive. The problem is what happens next. Releasing a rat or mouse elsewhere usually just moves the problem, and the animal may not survive in a new spot. If you use them, check them often so the animal doesn't die of heat or stress, which happens quickly in Florida.
Glue boards
The University of Kentucky material calls glue boards very effective, especially against mice, and notes captured mice soon die of suffocation. They also catch pets, lizards, birds and frogs by mistake, which is common on Florida lanais and in garages. If glue gets on a pet's fur or a child's skin, the same source says mineral or vegetable oil removes it. Most homeowners are better off with snap or enclosed traps.
Where to put traps
Placement decides whether traps catch anything:
- Along walls, with the trigger end against the wall
- Where you see droppings, rub marks or gnawing
- Under sinks next to pipe holes and behind appliances
- In the attic along top plates, beams and runways through the insulation
- In the garage along the walls and behind stored items
Mice usually stay within 10 to 25 feet of their nest, according to the University of Kentucky, so traps should be close to the droppings. Norway rats travel farther, 50 to 150 feet on average. For roof rats, which are cautious about new objects, leave traps unset for a night or two before baiting and setting them.
What to use for bait
The University of Kentucky lists peanut butter, bacon, raisins and fruit as baits that increase trapping success. A small amount is enough. Roof rats in Jacksonville respond well to fruit and nuts. Tie dental floss or thin string around the trigger and smear bait on it so rodents have to tug at it.
Outdoors, UF/IFAS advises setting rat traps only from dusk to dawn to avoid catching non-target animals.
Trapping in a Jacksonville attic
Attic trapping for roof rats has its own rules. Lay a plank or piece of plywood across the joists so you aren't stepping on the drywall, and wear a mask and gloves. Put traps where the rats travel: on top of the wall plates along the eaves, beside the openings you suspect, and on beams that cross the attic. Tie traps down with wire to a rafter or joist so a rat that is only caught by a foot can't drag it off.
Go up early in the morning in summer, when the attic is coolest. A Jacksonville attic in the afternoon is dangerous to work in. If you can't check attic traps every day, enclosed traps or a technician's visits are the safer choice.
When traps aren't enough
If traps catch rodents for weeks and the catches don't slow down, rodents are still getting in. Traps can't fix open gaps. Pair trapping with exclusion and sealing, or have a technician set up trapping and removal with return visits. If you want to compare against store-bought bait, the license guide covers what EPA allows consumers to buy.

What is the most effective mouse trap?
A simple snap trap set against the wall where you find droppings. Enclosed snap traps and electronic traps are good where kids or pets are around.
How many traps should I set?
More than you think. Thumbtack notes that a small infestation in an average home may need 12 to 15 traps. Place them close together where activity is.
Why aren't my traps catching anything?
Usually placement. Move traps against walls where droppings are. Roof rats may need traps left unset for a night or two first.
Are glue traps humane?
Animals caught in glue die slowly, and glue boards catch pets and wildlife by mistake. Snap traps are quicker.
How often should I check traps?
Every day. A dead rodent in a hot Jacksonville garage or attic smells quickly, and a full trap can't catch anything else.
