What are the noises in my attic?

Find out what insects and or wildlife you have in your attic that is making all those noises from our expert Scott Winsper.


Interviewer: What are the noises in my attic?

Scott Winsper: Well, there could be several noises in the attic you’re hearing to identify what’s going on. One could be a running pattern back and forth, like kids are chasing each other in the attic. That’s usually common as a flying squirrel. Another slight scratch noise in your sheetrock, usually it’s common to be a rodent, a mouse. If you’re hearing noises around 7:00, 12:00, 3:00, that’s usually common as a grey squirrel or red squirrel.

If you are hearing these noises, the best thing to do is call a technician.

Interviewer: What animals are making holes in my house?

Scott: Several things you should be looking for around your structure, for holes. One is, look around your foundation. Anything the size of a thumbhole or a pinky hole is common from a rat to a mouse. Anything from a racquetball to a tennis ball-sized hole around the foundation, is common by a red squirrel.

If you look up top of your structure, near your gable vents and your soffits, any racquetball-sized holes or tennis ball-sized holes, probably common by a grey squirrel. Anything bigger than that, the size of a basketball hole or anything like that is common by a raccoon. Usually they’ll enter through gable vents, roof vents, ridge vent covers, several things like that.

Interviewer: What happens if you don’t take care of an animal infestation?

Scott: First thing is, if you don’t take care of the situation, you can have common problems. Chewing on the wires, first of all. Rodents’ teeth grow consistently, all the time, and they need to file them down. Usually the most common thing is, they like to chew on Romex wires in the attics. Other thing is insulation. They like to bundle up your insulation, use it as bedding. Other thing is fecal matter, their poop, the urine. They destroy your sheetrock. Common areas is that they saturate your wood in the attic.

If you don’t take care of the problem, the problem’s going to persist and it’s going to get bigger and bigger, as each year follows. They each have litters, and more families move in. And as that comes, it causes bigger problems in your attic. So the best thing to do is to address these problems and get them handled before it’s a bigger problem.

Interviewer: What is the process of removing animals from my house?

Scott: The first thing you need to do is identify the active entry point. Once that is identified, then you need to identify the secondary entry points. What you need to do is seal up those secondary entry points. Then the active entry point, what you need to do is you put a one-way device on. It could be E40, a constantine tube. It has to be a one-way device.

Once that is done, we’ll return two to three weeks later on, remove those devices and seal those areas.
