Which Animal is in My Attic—and How Dangerous is It?

Identifying which critter is making its home in your house is sometimes difficult when all you hear is movement in the attic or walls. If you're hearing heavy footsteps, stomping, thumping, pawing, digging, chewing—or any similar sounds—in your walls or attic, give us a call and learn more below about which critters could be your culprit.

Bats In The Attic

Bats in the attic will cause many problems for homeowners. Roosting bats will create a terrible mess of droppings that will lead to:

  • Difficult Stains & Odorsbat in San Antonio home

    • Like all wildlife, bats are not known for their hygiene, and the odor is only amplified if the animal has died in your wall or somewhere else in your attic. Our high-quality, professional deodorizers will help restore your home's original smell as if the animal was never there. We can also repair any stains that are caused by wildlife in your attic. If the bats are hanging over your drywall ceiling, their droppings will lead to staining on your attic floor.

  • Health Hazards

    • If inhaled, bat guano may cause histoplasmosis. This disease may lead to serious complications if left untreated. Other diseases transmitted through bat urine or guano include salmonellosis.
    • Bats can directly transmit diseases such as rabies and external parasites from bats like fleas, ticks, and bat bugs can also transmit diseases to you. Keep your family safe and get bats out today.
  • Bat Noises in the Attic

    • Bat noises sound similar to mice scratching in your attic. Because bats are nocturnal, you'll generally hear them scratching around late through the night into the early morning. You may also hear chirping or crying sounds in the attic, or you could hear their wings fluttering. 

  • Ruined Insulation

    • When bats hang over your insulation, their droppings seep in and soil it. If the insulation is soaked in urine and feces, it will not perform. Bats' droppings and secondary pests they're known for carrying will all lead to unusable insulation, which can impact your home's energy efficiency.

Mice And Rats In The Attic

Hearing movement in the walls? Your culprit could be rodents. Mice and rats are destructive and dirty animals. The droppings willWildlife Control in San Antonio attic accumulate quickly and cause difficult odors and stains. If you suspect a mouse or rat problem in your attic, call now! A few mice or rats can turn into an infestation quickly.

  • Ripped & Soiled Insulation

    • Wildlife commonly uses insulation for nesting, and rodents are no exception. Rodents typically will use insulation for nesting in one of two ways: they'll rip and drag insulation as needed to create a nest in a secondary location or they will nest inside the existing insulation.
    • When rodents get into your insulation, they run through it leaving their urine and droppings along the way.
  • Electrical Hazard

    • Mice and rats will chew on electrical wires for several reasons. The most common reason is to keep their teeth sharp. Rodent teeth are constantly growing, and chewing on the hard outer material of the electrical wires helps to keep them short. Did you know rodents can also be responsible for chewed waterlines?

Our team has the experience to replace insulation if the damage is significant enough to affect the energy efficiency of your home. Call Critter Control of San Antonio today for more information.
  • Mice & Rat Droppings

    • Mice and rats are unhygienic. Mouse droppings are usually less than 1/4" long and found wherever mice are present in your attic; that is to say all around! Many homeowners often spot the droppings before they see the actual mouse, if at all. Rat droppings, too, are plentiful around where the rats have resided. Rat droppings are slightly longer than those of mice.
    • Both of these droppings have the potential to transmit diseases through their feces, often passing along salmonellosis, tularemia, and leptospirosis to humans.
  • Mouse Noises in the Attic

    • You'll likely know you have mice or rats in your attic if you hear scratching or scurrying noises. The time of the day in which you hear the sounds can help you rule out squirrels—squirrels are most active during the day. Mice and rats are most active during the nighttime hours. 

Squirrels In The Attic

If a squirrel or multiple squirrels have found their way into your attic, the damages may be extensive! Squirrels are crafty and resourceful animals that are capable of significant damage to insulation, wiring, and structural materials in your attic. If a squirrel enters your attic to nest, they will find their way back in if removed by untrained homeowners. We recommend using a professional squirrel removal company like Critter Control to keep squirrels out permanently.

  • Chewing on Wiressquirrel in San Antonio

    • Because squirrels are a member of the rodent family, they also have constantly growing teeth. For this reason, one of their primary damages to your attic will be compromised wires—which can present a safety hazard.
  • Squirrel Droppings

    • Often confused for rat droppings, squirrel droppings can be extremely harmful and will require full sanitation. Handling squirrel feces can lead to contracting diseases such as leptospirosis, typhus, and tularemia
  • Nesting Female Squirrels

    • Another major problem associated with squirrels in the attic is the mothers who have recently had a litter of squirrel kits. Not only is your attic itself used for nesting (ripped insulation, etc.) but now there are babies to consider, which makes removal all the more difficult.
  • Squirrel Noises in the Attic

    • Common squirrel noises to hear in your attic include scratching and scurrying. If you hear the noises during the daytime, you likely have a squirrel living in your attic. Squirrels are active during daylight hours, while mice and rats are active at night. Squirrel noises sound similar to rodent noises, so the time of day you hear the activity will help you pinpoint which type of animal you're dealing with. 
  • Attic Entry Points

    • The fact that the squirrels got in somehow is another aspect of squirrel removal and prevention to consider. They likely caused significant damage getting inside with their notorious ripping and chewing habits, and they can easily chew through plastic. Did you know squirrels can even chew through lightweight aluminum vent covers?
