Wikipedia tells us:
Chiroptera (Chiroptera ), commonly called bats or bats, are an order of the class of mammalia, counting nearly a thousand species, or a fifth of mammals, therefore the most important after that of rodents (Rodentia).

Bat life cycle
2 phases mark the reproduction of bats of any species:
The breeding of bats starts in the fall and lasts all summer. Bats mate at gatherings commonly known as swarms.
In fact, all bat species gather in large numbers in the caves that serve as hibernacles. This gathering is at the origin of the diversity of species.
Bats mate after a courtship of songs or chases. After mating, the female holds the male’s sperm in her uterus.
Fertilization only occurs during the spring. It is during this season that hibernation takes place.
Because there are a multitude of bat species, the gestation phase differs by species. Temperature and diet also condition this phase.
For example, the gestation period for eastern pipistrelle is 44 days, double the gestation of grey mice. For other species, it can last up to 90 days.
2nd phase: the birth of the young
In the year, a female gives birth to only one cub. Exceptionally, the red bat can give birth to up to 4 cubs.
To give birth, the females gather in colonies. Most get on their feet with their heads pointed upwards, allowing the newborn to be recovered upon release.
Some species stand with their heads pointed downwards. At the exit, the little one clings to his mother’s fur and spends a few days there.
At birth, baby bats are pink in colour. They have no hairs, but are covered with downs. Their eyes barely open.
The hairs of the young become visible 14 days after birth.
Mothers breastfeed for five weeks, then weed the young. They then go out every night, looking for food.
The growth of small children is accelerating. The weight, the size, the wings, everything indicates that they are reaching adulthood.
As soon as they are 18 days old, the cubs are able to spread their wings and take flight.
They then feed on insectsthemselves.
From July to August, all bats, males, females and offspring stock up on fat to cope with the hibernationperiod.
They migrate to caves, caverns, old buildings to shelter there: this is the critical period of uncontrolled installations in your shelters
Bats have a lifespan of 30 years.
How are theseswallows harmful to us?
Bats take refuge in the ledge, under the roofs, under the exterior cladding or in the attic.
They leave faeces and smells in their path. Their undesirable presence attracts parasites such as ticks or flies. They leave ugly traces on the structure of the buildings. They disturb by making noise.
Bats can cause diseases such as histoplasmosis.
Histoplasmosis is an infection caused by the absorption of products containing spores of the fungus(Histoplasma capsulatum). This fungus is found in the fur of the critter and spreads when it beats the go.
Bats can also transmit rabies, and its rabid bite could be fatal.
It is therefore strongly recommended to wear gloves before touching this mammal and then disinfect them after handling.
5 Tips to Prevent Bat Intrusion
- Block the exits through which the bat could enter your home. Use silicone and mortar. Also use mosquito nets or polypropylene bird nets. Use staples or small nails to hold everything in place.
- Possibly install lamps in your attics that flash at a frequency of 10 seconds,
- Put an ultra-sound device in areas that may be invaded to keep them away.
- Light wicks of sulfur for 3 successive days. This product has the effect of making it difficult for them to breathe.
- Burn incense sticks in every room of the house.
Capture of bats:
The solutions used by the professional exterminator
It is dangerous to handle bats. This is one of the reasons why it is better to entrust their capture to an exterminator in Montreal, Que.
Several ways to capture them:
- It will use repellents such as mothballs, lights, drafts. For the exterminator, this method consists of getting the critter out of its hiding place in order to capture it.
- He’ll install bat nest boxes. By this method, the exterminator lays bat nest boxes outside the house. The temperature in the nest boxes means that pregnant bats take shelter there while the exterminator finds another environment conducive to the birth of the young.
- It will directly capture the bat using a cylindrical device barbed with wires surrounded by a smooth metal ring.
- He will capture the animal with a cotton bag securely attached to a metal funnel.
The professional in wildlife relocation:
- Has an authorization from the Quebec Ministry of Forests, Wildlife and Parks for the capture and relocation of wild animals;
- Holds a C5 licence from the Quebec Ministry of Sustainable Development; This means that it captures bats by following Canada’s Environment regulations;
- Apply a specific and precise work plan;
- Uses certified professional bat capture technicians;
- Identify the source of the invasion and measure the intensity of the attack,
- It uses the appropriate capture method.
- Intervenes with total discretion, uses vehicles not resembling exterminator vehicles.
- Has a written guarantee on the effectiveness of his bat capture.
