Engineers working for the Texas Department of Transportation are trying to make the state’s bridges and related infrastructure more hospital to bats for a number of reasons as the nocturnal flying rodents help to naturally suppress the insect population without the use of pesticides while acting as pollinators to assist in flowering plant reproduction.

In fact, over 500 plant species rely on bats to pollinate their flowers – including species of mango, banana, durian, guava and agave, which is used to make tequila.
