How Long Do Bats Live?

Bat Life Expectancy

Most bats live less than 20 years in the wild, but six species can live more than 30 years! In 2006, this tiny bat made it to 41 years and set a record for the oldest bat.

Some bats return to the safe roost year after year. So if you have bats in your attic, it might turn into a 30 year problem.

Bat Life Cycle

The bat life cycle begins after the flying mammals emerge from hibernation. Females and males will mate multiple times with various partners to ensure success with fertility. Once they find a roost, females undergo a 50 to 60 day gestation period. They give birth to a single pup, and the young bat will cling to its mother. In fact, these newborns even attach themselves to her body while she's in flight. Within nine months to one year, both female and male bats will become sexually mature.

Baby Bat Life Expectancy

When baby bats are born, the pups are blind and helpless. Female bats gather in warm areas, such rafters, and attics, to form maternal colonies. A baby bat clings to its mother fiercely at first, and the mother only leaves for short periods in the evening to hunt.

As pups grow and develop, mothers slowly increase their hunting time to wean their offspring. Once the baby bats are about five weeks old, they begin to fly and hunt but may still nurse until they can feed on their own.

Problems Caused by Baby Bats

Bat babies are most likely to enter a home by accident when they are learning to fly. Once inside, they may panic and fly erratically in an attempt to escape. While bats can carry rabies, the frightened behavior of a baby bat does not mean the animal is sick. Opening doors and windows to let it out is the best approach.

People should never attempt to handle or touch wildlife, especially bats. Not only can they spread rabies, but the pests also transmit histoplasmosis through their waste. Trutech provides homeowners with expert service and humane solutions to bat problems and infestations.

Problems with the Bat Lifespan

If they are able to survive their first winter, bat lifespans can reach twenty to thirty years. Bats return to the same place to roost year after year. If that roost is in your attic, a bat problem could last decades.

The pests occupy and damage attics, chimneys, and other buildings for an extended period of time. Most destruction to structures occurs from the buildup of bat guano. Not only do their droppings create a foul, musky odor, but they are also responsible for spreading histoplasmosis, which can be harmful to humans and pets.

Controlling the Bat Lifespan

Bats can be very beneficial to have around, as they eat thousands of insect pests in the night air. However, when roosting in homes, they can create many problems for homeowners. In addition to sealing all cracks to ensure these pests don't get inside, homeowners are encouraged to build bat houses in their yards. These structures provide an alternate shelter, safe from predators and the elements.

If the pests continue to roost in structures, the professionals at Trutech can assist in safe removal.
