Flying Squirrels

Connecticut’s is home to Southern Flying squirrels, These are nocturnal creatures, and usually a fall and winter pest in our attics. When you have flying squirrels in the attic during winter it is typically 10-40 squirrels not one or two. You will hear them at night between 9PM to around 4AM. Flying squirrels store lots of food in their dens. you will hear them hoping from entry point to their food stash, and between their latrine and their sleeping area.

  • Flying squirrels hop when they run. The skin flap is made for gliding not running.
  • You may hear them glide into the side of the house or roof. Listen for a thump then hopping take note to what direction they take.
  • listen out for where they are sleeping. In the morning you can do a bang test to see if what you are hearing is flying squirrels.
  • When you bang on the spot in the AM if you hear running 9/10 its flying squirrels. Mice freeze, squirrels run, and bats ignore you completly when doing this bang test.
  • Some nights it will sound like a party is going on others it will be silent. Take note of weather patterns they will tend to come in for cold and snowy weather.

Bats

Bats will get under insulation, you may hear them crawling in winter time when they are hibernating. They will move to the perfect temperature to hibernate. If you hear movement one day and then hear it again weeks later it could be bats. If you bang on the area you are hearing them bats will typically ignore you.

  • The best way to determine if bats are the problem is by the droppings. If you see droppings that look larger than a mouse take something and crush one. If it turns to dust you have bats 100%. Only bat droppings turn to dust like this, but you can take a flashlight and see the bug parts (they will be shiny).
  • Bats will squeak like mice, actually if someone says they heard squeaks most the time it is a bat problem.
  • During late spring through summer you may hear bats leaving in the evening as the sun goes down they may jockey for position near the exit. On hot days you can sometimes hear them fighting each other in annoyance.
  • If you hear this take a walk outside bats will drop out their entry point and swoop away commonly doing a lap around the house.

Mice

Mice are very common attic animal in Connecticut attics. Most people who call me with mice say it sounds bigger defiantly not a mouse. Deer / White Footed mice are loud, they will pin an acorn on the sheetrock under the insulation and gnaw on it. This will create a speaker like effect making them sound much larger.

  • Deer mice are much louder than you would believe.
  • If you look into the attic you will usually see holes in batton insulation, or holes and trails in blown in insulation.
  • Most people know what mouse droppings look like, it is uncommon for me not to find mouse droppings in Connecticuts attics.

The least common animal I have ever found in an attic was a dead mole. I wish I could explain how a mole got into an attic, but some mysteries can never be solved.
