Mice love to live in attics. These animals are classified as "commensal rodents" because they thrive in association with people. To the House Mouse, a house is a far better shelter than anything out in the wild. And the best part of the house is usually the attic. Though these mice do also live in the walls, the basement, your kitchen pantry, and so on. But the attic is usually the home base. The first sign of mice in the attic is the scurrying or scratching usually in the ceiling or walls during the night hours. House Mice are nocturnal. They are small, so the noise is usually a faint pitter-patter. But depending on the type of drywall or insulation in your house, and the acoustics, they may sound louder and larger than mice. One reason mice use your attic is to establish nesting areas. A female mouse can have up to 10 litters of young per year, and up to a dozen young per litter! And mice are able to reproduce when only six weeks old! This is the reason mouse populations can explode to infestation levels very quickly. Though the limiting factor is usually food availability. They are very capable animals, and they can climb almost any surface and jump very far. They can squeeze into very small holes, about the size of a dime, or a gap in the architecture as little as 3/8" thick! It's amazing! Thus they have no problem finding the entry points into your attic - usually through many areas from ground to roof, from poorly screened roof vents, places where the soffit meets the roof, eave vents, loose siding, areas where pipes enter, even the plumbing system. Your home might have several entry areas. The general process to get rid of mice in the attic is as such: First, inspect the house to find out how the mice are getting inside. Second, inspect the attic to find out what kind of damage they have caused, from chewed wires to nesting debris. Third, seal shut 100% of the entry holes, with metal or steel screen, which they can't chew. This is important - seal first! Then trap and remove the animals, most commonly via trapping with snap traps or with one-way exclusion doors. DO NOT USE POISON. Read about how to kill mice. Fourth, repair any damage such as chewed wires, and clean and decontaminate the attic if necessary. You may want to get rid of mice in the attic fast and easy, but to do it correctly, and to do it permanently, it is work. Read more about how much does mouse removal cost.
A full inspection of the exterior of the home, including the roof and all vents, to find out how they are getting in. Plus an inspection inside the attic to identify mouse damage.
The job will fail unless you solve the source of the problem. Seal shut the entry holes, with professional grade repairs, or else the problem will happen again.
AFTER the repair job, set at least a dozen snap traps throughout the attic on the areas of high mouse activity. Use wooden snap traps baited with peanut butter.
In addition to repairing chewed electrical wires and damaged duct work, you might want to remove the mouse feces, maybe the insulation, and decontaminate.
HOW MUCH DOES MOUSE REMOVAL COST? Prices vary depending on the situation. Some jobs are simple, require only one service visit, and might be as low as $100. Some jobs are complex, require multiple service visits, home repairs, attic cleanup, and so on. Prices can also vary by city.

Is there a nest of baby mice? Yes, maybe a few. Mice can breed at very high rates. They keep nests in the attic and walls. When removing raccoons or squirrels from an attic, this nest of young is something to consider. But with mice, the nest(s) may be very hard to find, and the young unable to be saved, so I have not made the remove of mouse nests an active part of my mouse control activities. If you are concerned about baby mice in an attic, the best bet is to prevent the issue in the future by making hour house mouse-proof. Read more about nest of baby mice in the attic.
What kind of damage is caused by mice in the attic? First of all, they are rodents, so they chew. They are small, so chewing on wood may not be a big deal. But they can chew on important things like electrical wires or PVC pipes pr PEX tubing for radiant heat systems, or small holes in ductwork, things like that. Electrical wires are a problem because of outages, or exposed wire, which can be a fire hazard. Mice often dig tunnels in the insulaton, and deposit nesting material there, if that bothers you, although I don't consider that a big problem. They do leave feces and urine in the attic, bringing plant matter and nesting material into the attic, chewing on wood beams in the attic, and chewing on electrical wires in the attic. Some of these activities are merely unsanitary, but some can cause a risk of fire hazard. Read more about damage from mice in the attic.
How do I trap mice? Trapping is the most effective means of mouse control. But it is only effective after the whole house has been mouse-proofed: that is, all possible mouse entry holes have been sealed shut with steel repairs. It is pointless to begin a mouse trapping program if the house has not been sealed shut. First of all, new mice will continue to enter the house indefinitely as long as they can find open entry holes. Second of all, it is far easier to trap mice once those holes have been sealed shut. Mice are creatures of habit, travelling the same pathways over and over again - like mice in a maze! Once their normal exit/entry holes into the house have been sealed, they change their behavior and seek alternate territory, and seek alternate food. They are far easier to trap at that time. But what type of trap to use? You can purchase several styles and designs of mouse trap. There are many types of snap traps, electricution traps, live cage traps, repeating live traps, glue traps, and so on. This site is focused on humane treatment of animals and effective solutions to problems. There is no way to humanely trap mice in live traps. If you block them out of your house, they are done for. They will not survive more than a few days outside, and will be eaten by predators. So it's pointless to live-trap them. It's also incredibly inhumane to use glue boards. Read about inhumane glue boards. The best trap is actually the old standard wooden snap trap. I prefer Victor brand. I have tested over 14 types of mouse traps so far, and nothing is as effective as these original wooden snap traps. They can be set in high numbers, on the mouse runways, the flat bottom holds them steady in insulation, and the pan tension can be adjusted to hair trigger. Nothing is better. Remember, the key to successful trapping is in sealing shut the house first, then in placing the traps directly on the mouse runways second. Bait is of least concern - peanut butter, or a variety of foods, work fine. You actually don't need any bait at all. Read more about mouse trapping and about the best type of mouse bait.
Can't I just use a mouse repellent? No. In my 15+ years as a wildlife removal professional, I have seen it all: attics filled with strobing lights, blaring radios, ultrasonic sound machines, and every type of over-the-counter repellent, from coyote urine flakes, to ammonia, to the end-all-be-all el cheapo scam, mothballs. I once went into an attic in which a desperate old lady had dumped close to 100 lbs. of mothballs in her attic. The mice didn't care! Here's the problem with repellents in general: once a mouse lives in your attic, and has a nest of babies there, that's it. That's the only option for survival. There is no device, no repellent that will make them leave. Go ahead and buy a mouse repellent at Home Depot, or a mouse deterrent device online - waste your time. But they have zero demonstrated effectiveness. Read more about mouse repellents.
Can I kill the mice with poison? Most pest control companies use poison for rodent control. They treat rodents the same way they treat insects. The main goal of the pest control company is to never solve your mouse problem. They want to put you on a quarterly contract that you pay for, for life. And poisons accomplish that goal: they never solve the problem. As long as your house has open holes and gaps that allow mice to enter, you will forever have a mouse infestation. Poison does kill a few of the mice. But not all! Here are the problems with using poison to kill mice. First, not all of them eat the poison. Second, not all of the mice that do eat poison actually die. Third, the mice that live reporoduce so quickly that the population will be back to full level in just a few weeks. Fourth, death by poison is painful and inhumane, by internal bleeding - you may not care, but mice have every bit as much feeling as your pet dog. Fifth, the mice that do die will die in your attic or walls (not that bs myth that "they go outside to drink water"), and the smell of rotting mice caused by poison is horrible - I remove this stink almost every day. Sixth, IT NEVER SOLVES THE PROBLEM because as long as you have open holes leading into your house and attic, you'll have mouse problems. You must find and seal shut all of these entry holes. Poison is basically a gigantic hoax perpetuated by a greedy and sleazy billion-dollar industry. Don't fall for this hoax! Do your mouse control the correct way!

How do I keep mice away from my house? Maybe you want to prevent mice from coming to your house, roof, garden, or property in the first place, before they get in the attic. Well, it's hard to keep mice away from a property. They can pretty much go wherever they want, and they will, if there's adequate food and water sources. The real key, regarding mice in the attic, is to prevent them from getting inside. On the roof is fine. Inside is not. To do this, you must inspect the house and seal shut any potential mouse entry holes, with steel, which mice can't chew through. Other than that, your best bet is to eliminate things that attract mice to your property, such as bird seed, garbage, pet food, fruit plants, water sources, clutter and debris and so on. That said, even the cleanest property is likely to be a good habitat for mice, so there's not much you can do to keep them away from your house. But you can keep them OUT of your house. You can read more about how to keep mice away if you want.
How do I do this myself, for cheap? Follow the 4 steps. First, use a ladder and inspect every inch of your house, especially the roof vents, plumbing stacks, eave gaps, soffits and soffit vents, and everything at ground level too. Then inspect inside the attic to find out more clues about how many mice there are and where they are most commonly entering. Seal shut every possible entry hole using steel mesh, which mice are unable to chew through. This first step is by far the most important thing, and the only crucial thing you must do. Second, set at least a dozen or more snap traps in the attic, on areas of mouse activity (look for droppings and trails in the insulation), baited with peanut butter. Continue trapping until no more are caught, and no more sounds are heard. If this takes more than 3-4 days, you probably missed an entry spot or two. Third, once they are all trapped and removed, repair any chewed electrical wires in the attic, and clean the feces and urine. Read more about mouse feces. The whole process is difficult, and it took me a couple of years and dozens of jobs before I got very good at it, but if you are very careful and work hard, you can do it!
