Building Bathouses For Microbats

microbatMicrobats are natural insect terminators.  These little mammals  weigh around 3gms  - 150 gms and have a wingspan of approx 25 cm. Being nocturnal creatures they use echolocation to navigate and find their insects in the dark. Contrary to popular myth, the bats are not blind and do use their sight as well.  The largest species has a body length of only 11 cms.  A single microbat can eat  up to 1,200 mosquitoes and small insects in an hour which has earned them the well deserved reputation of being the nature's mosquito busters.  They also pollinate native flowers, many of which can only be pollinated at night. Microbats like their bigger cousins the flying foxes (also called megabats) are a vital part of the ecology of our forests and planet. Recent surveys in Australia have shown that in grain-growing regions, the microbats fed solely on grain weevils, thus helping crop protection by reducing the use of pesticides.  Microbats also eat midges, termites, lawn grub moths and other harmful insects.

The Real Facts About Bat Transmitted Diseases

Grey flying foxThe incidence of Australian Bat Lysavirus (ABLV) in wild bats is about the same as the incidence of HIV in humans: between .09% and 1.2% of free-living population (1,2)

The instance is higher in sick animals that come into care. Bats with ABLV always die.

Responsible for two deaths (one of whom refused treatment). Post and pre-exposure treatment is 100% effective - not one vaccinated person has died from ABLV.

ABLV is saliva-borne and lives a short time outside the body.

ABLV kills. Vaccination is ESSENTIAL. In every continent except Australia and Antartica veterinarians, carers and members of the public are routinely vaccinated.

Humans catch Hendra (originally equine morbillivirus) from horses, not bats

No bat carer has ever caught Hendra. Screening 128 long-term bat carers found none had detectable antibodies (Selvey at al., 2006)

Bats do not suffer from or die from Hendra, but authorities have found antibodies in the amniotic fluid of bats and suspect they may be a host for the disease.... however

"This is all speculation though as we know that bats carry the virus but we don't know exactly how it gets into horses." Dr Stephen Prowse (2008), CEO of the Australian Biosecurty Cooperative research Centre for Emerging Infectious Disease

Why Care About Bats? (Year of The Bat 2011-2012)

Bats are among the earliest mammals, experts dating them back to around 50 million years. Cave paintings in the Kimberley's dating back to the last Ice Age which was around 20 - 25,000 years ago feature bats as can be seen in the above image.
