What do bats hate most?

Bats hate things that threaten their safety, disturb their roosts, and expose them to predators, though as adaptable nocturnal animals they tolerate many conditions. What bats hate most includes bright lights at night, because they are nocturnal and prefer darkness for hunting and roosting, and artificial lights can disrupt their emergence and feeding, though some bats hunt insects around lights. They hate loud, sudden, unpredictable noises that signal danger, such as shouting, banging, and machinery near roosts. They hate being disturbed in their roosts during the day when they are sleeping, because disturbance causes them to waste energy, abandon pups, and move to less suitable roosts, which is why cave and attic roosts should not be disturbed. They hate strong, irritating smells like strong chemical cleaners, mothballs, and predator urine in their roost sites, though scent repellents are not effective long-term deterrents. They hate being unable to fly, as bats need to drop from a height to take flight and cannot take off easily from the ground, so being trapped on the ground terrifies them. They hate cold drafts and lack of warmth in winter roosts, as many bats need warm, stable temperatures for hibernation. They also hate strong winds and rain that make flying difficult. Most of all, bats hate loss of roost sites and food, so sealing entry points with one-way exclusion devices and removing insects with pesticides are what they dislike most.
