How do bats get into my Attic?
Most often bats find their way into homes through cracks and crevices in building materials. Their small size makes it easy for bats to tuck themselves into even the smallest of gaps. They can squeeze through holes as small as 6 millimetres or about the size of a dime. Once inside the structure, bats will roost in attics and between walls. Many homeowners dealing with a bat problem will inspect their attics expecting to see them hanging from the rafters. The truth is that in most cases their exact location inside the home is far more difficult to determine as they are more likely to be found in soffits, walls and below the insulation.
For this reason, a quick look inside your attic from the top of a ladder is usually not enough to determine the presence of bats. There are other ways to know if there are bats nesting on your wall or attic. Look for small holes in the structure of your walls, which can be signs of entry. Listen to strange sounds like screeching, chattering, or scratching. You can also detect them by smell; their droppings and other remains emit a certain smell, similar to those or rats and gerbils.
Bats are the only mammal capable of true flight and therefore are most likely to enter a home above or along the roof, often in areas that are difficult to see from the ground or access safely. Their physical makeup means that they are able to slide themselves into very small openings. To help them do so, a bat’s fur is very oily. Bats use odour and scent cues to help guide them and other members of the colony to their exit and entry points. Over time, repeated entry and exits from the same space on a home will produce grease stains on building materials. It is critical to identify all entry points.

Droppings, or guano, are also a tell-tale sign of a bat infestation. Bats leave droppings behind everywhere they go. They can be found throughout attics, soffits and walls where bats roost as well as on exterior walls and on roofs where bat enter. An accumulation of bat droppings is often an excellent indicator of a nearby entry point.
Bat guano appears slightly larger in size as compared to mouse droppings. Apart from size, bat guano can be differentiated from mouse droppings by texture. Bats and mice have different diets and as a result bat droppings tend to dry much more quickly and will flake away to dust under any pressure. The tendency for bat droppings to turn to dust and become airborne makes them especially dangerous. Continuous exposure and inhalation of bat droppings and their fungal spores can cause a condition known as histoplasmosis.
Do It Yourself Bat Control Measures that Don’t Work
- Bright Lights – bright lights are not guaranteed to make the bats leave your home. Shining a bright light can actually attract the bat even more and confuse it when trying to escape from your house. You are better off reducing the glare of the lights so that the bat can see well enough to escape without frightening it.
- Ultra Sonic Noise and mothballs – these are not effective in eliminating bats, especially to mother bats that need safe shelter for their young. They will put up with anything just to maintain their colonies. For the determined mother bat, no amount of noise and mothballs can make them leave their safe haven.
- Bat Houses – these bats can’t be easily tricked to vacate their safe nest inside your home and transfer to unfamiliar shelter. Once they find a shelter good enough to house them, they can’t be easily swayed to leave. If they actually transfer to the bat house you installed, you will have another problem on your hands, which is liability. If the bats multiply in the new shelter and takes up residence in your neighbors’ houses, they you are the one responsible in case of bat-related injuries and mess.
- Exclusion Problems – these include sealing the home during winter assuming the bats have left for winter, or sealing the home during the birthing season and locking babies in. Sealing the home at night assuming all bats have left or sealing only the current entry areas and ignoring potential entry points (bats will always find new areas) will not work too.
