Megabats are threatened by habitat destruction by humans.
Deforestation of their habitats has resulted in the loss of critical roosting habitat.
Deforestation also results in the loss of food resource, as native fruit-bearing trees are felled.
Habitat loss and resulting urbanization leads to construction of new roadways, making megabat colonies easier to access for overharvesting.
Additionally, habitat loss via deforestation compounds natural threats, as fragmented forests are more susceptible to damage from typhoon-force winds.
Cave-roosting megabats are threatened by human disturbance at their roost sites.
Guano mining is a livelihood in some countries within their range, bringing people to caves.
Caves are also disturbed by mineral mining and cave tourism.

Megabats are also killed by humans, intentionally and unintentionally.
Half of all megabat species are hunted for food, in comparison to only eight percent of insectivorous species, while human persecution stemming from perceived damage to crops is also a large source of mortality.
Some megabats have been documented to have a preference for native fruit trees over fruit crops, but deforestation can reduce their food supply, causing them to rely on fruit crops.
They are shot, beaten to death, or poisoned to reduce their populations.
Mortality also occurs via accidental entanglement in netting used to prevent the bats from eating fruit.
Culling campaigns can dramatically reduce megabat populations.
In Mauritius, over 40,000 Mauritian flying foxes were culled between 2014 and 2016, reducing the species' population by an estimated 45%.
Megabats are also killed by electrocution.
In one Australian orchard, it is estimated that over 21,000 bats were electrocuted to death in an eight-week period.
Farmers construct electrified grids over their fruit trees to kill megabats before they can consume their crop.
The grids are questionably effective at preventing crop loss, with one farmer who operated such a grid estimating they still lost 100–120 tonnes (220,000–260,000 lb) of fruit to flying foxes in a year.
Some electrocution deaths are also accidental, such as when bats fly into overhead power lines.

Climate change causes flying fox mortality and is a source of concern for species persistence.
Extreme heat waves in Australia have been responsible for the deaths of more than 30,000 flying foxes from 1994 to 2008.
Females and young bats are most susceptible to extreme heat, which affects a population's ability to recover.
Megabats are threatened by sea level rise associated with climate change, as several species are endemic to low-lying atolls.
