Two species of bats are found throughout Canada - the Big Brown Bat and the Little Brown Bat. They have slightly different life-cycles and characteristics and as such are handled differently by wildlife removal experts. The following are some more bat facts for Vancouver homeowners:
Urban: In urban environments bats are found in semi-open areas often near trees and water but will make their roots inside building spaces.
Time of year: Bats mate in the fall and sometimes into the winter months. Sperm is stored and ovulation and fertilization are delayed until the female emerges from hibernation.
Litter size: Big Brown Bats have one to two offspring every year while the Little Brown Bat has only one.
Rearing: Little Brown Bats will stay in the roost for the first 18 days of their life and can fly thereafter. They reach maturity within 3 weeks. Big Brown Bats take longer to mature and do not reach adult size until 70 days.
Sexual maturity: Female bats are sexually mature near the end of their first year. Male bats take slightly longer and will reach sexual maturity after their first year.
Time of day: Bats are nocturnal and use high frequency echo-location to seek out their food.
Diet: Big Brown Bats eat a variety of insects but prefer beetles. Little Brown Bats enjoy flying insects like midges, mosquitoes and mayflies.
