Mice cause damage to property and electrical cables, and they have certain health risks associated with them, as they carry Salmonella, amongst other things.

Is It Common To Have Mice In The Attic And How Can I Tell If It Is Mice?

It is common to have mice in your attic. Mice are away from the danger of predators and humans up in the attic, there will be warmth from the heat rising, and items to use for nesting.

Is there insulation in the attic? This will make comfy bedding for a mouse. Like clutter, insulation can provide hiding places for a mouse, so it is worth getting the insulation checked through.

Droppings

You might spot randomly spread mouse droppings in the attic. Be cautious! Mice can carry 30 odd different types of diseases, and their feces and urine help to spread it. Careful removal is required. Besides diseases, mice can also bring into the home ticks, fleas, other insects and bacteria.

House mouse droppings can be either dry or moist. Whichever you find, make it your business to dispose of it safely.

Nests

Mice and rats will chew through paper, cardboard, and furniture in order to make nests. If you spot any chewed items, or the nests themselves, it could be signs you have mice in the attic.

The Smell of Urine

You may sense the strong smell of urine in the attic; more signs of mice.

Grease Marks

You might spot grease marks along the walls in the attic, about half an inch from the floor. This is a good way to identify a possible rodent infestation.

When mice move around in a house they will run along the walls, and the oil from their fur leaves a visible mark. These marks are signs of mice or rats.

Noises

You can often identify mice by the sounds they make at night.

Quite often this can be the first clue to infestations of mice. Sounds coming from the attic may be mice scratching and making holes in things. These pests can create a lot of damage in the attic and around the house.

The noise might stop during the day as mice are mostly nocturnal. They prefer it when predators are not around and will sleep during the day.

There are many different mouse traps to buy, poisons, and bait traps. Click here for more information

With a mouse infestation in the attic, you can bait to your heart’s content, as there should not be any children or pets venturing up there and being put in danger.

We recommend you use snap traps, or for a more humane approach, live bait traps, for getting rid of mice. Do not bait the snap traps with cheese, as it goes off too quickly. The rodents much prefer peanut butter or sunflower seeds.

We recommend the Press N Set bait trap, as it is easy to use, does not go off accidentally unless it has caught a mouse, and does not go off if you put it down on the floor.

Once you have baited and set the trap, place it against a wall, with the jaw side facing the wall.

How to Release a Mouse From a Bait Trap?

It is easier just to throw away the traps and the mice together, but if you want to reuse it, lift the snap wire up over the garbage bin and drop the mouse in.

Make sure the mouse is dead, as it could still be alive if only a leg for instance was trapped.

Bait the snap trap again and place it against a wall where the mice run along.

A Professional Pest Control Company

If you feel you are losing the battle or do not want to deal with, rodents you should call in the services of a professional to deal with infestations and get rid of mice in your attic for you.

Contact a company with a good reputation and good feedback reviews. You could ask friends or neighbors for contact numbers to call.

Ask if they offer a service that is licensed by the state and if they are members of a state or national association.

The service provided will include a plan of action, which will involve poisons or snap bait traps used in the home. Check with the professional exterminator to ask what will be used.

Find out before they start if they will be responsible for the removal of the rodents. This is quite an important question if you are squeamish or detest mice.

You could ask the pest control company to come back and check for rodents after the infestation has gone, just to keep an eye on future rodent infestations. New entry points may be found in the home by the company.

These extra visits will put your mind at rest, so we think it is well worth doing.

Top Tips On How To Repel Mice:

  • Check the exterior of the property, look at gaps in the eaves, missing brickwork, and check the whole of the roof. Once you identify entry points, seal them with steel wool and caulk. Do this regularly, as a well-maintained property is less likely to have mice than a run-down property.
  • Cover air vents with a wire mesh so that air can still circulate in the property. You should never completely seal or close up vents.
  • Check holes around pipes on the property, as these make easy entry points for mice and other rodents. Rats and mice can get through tiny gaps and holes. Sealing them will help prevent an infestation.
  • Check air conditioner connections for cracks and gaps and seal them off.
  • Sealing cracks and gaps will close up entry points to the home. Check around doors and windows for poor fitting and for any holes.
  • The rodents can access the roof and attics via trees. Trim the trees back to prevent them from getting onto the roof and into the attic. Vegetation provides hiding places outside for rodents too, so keep it trimmed also.

Food Sources

If you want to get rid of mice and any other possible rodents or insects in the home, you must remove all possible food sources.

As the weather gets colder, a rodent will be looking for a cozy home and food.

Here are a few tips to help keep them out.

  • Keep food put away, place food items in airtight containers.
  • Clear up food crumbs from the kitchen surfaces immediately.
  • Keep floors swept and crumb-free.
  • Do not leave piles of dirty dishes in the sink; a mouse only needs 3 grams of food a day, so tiny morsels on the plate would be welcome food to mice.
  • Keep garbage bins shut, empty often, and clean regularly in the home.
  • Keep garbage bins in the yard completely shut and check them for damage.
  • Don’t store grains and seeds in plastic containers in the shed.
  • Keep Christmas goodies out of the attic.
  • Check the children’s rooms for candy left lying around.
  • Try not to leave a bowl of meaty dog food out for too long. The mice and insects may get there before the dog does.
