Which of the following is NOT a method of controlling bat populations?

Controlling bat populations effectively involves various strategies that address the root causes of their presence and mitigate human-wildlife conflicts. Among the options presented, trapping and relocation are typically not considered effective or sustainable methods for controlling bat populations. This is because while trapping and relocating bats may temporarily reduce their numbers in a specific area, it does not address the reasons for their presence or prevent future populations from returning. Additionally, relocating bats can be problematic as they may not survive in new areas if the conditions are unsuitable, and it can disrupt local ecosystems.

In contrast, sanitation and cleanup, exclusion techniques, and public education and awareness are proactive strategies that contribute to long-term management. Sanitation and cleanup involve removing food sources and potential roosting sites, which can deter bats from inhabiting certain areas. Exclusion techniques focus on sealing entry points and making structures less accessible to bats, thus preventing them from roosting in human dwellings. Public education raises awareness about the benefits of bats and promotes coexistence, reducing fear and misinformation regarding these animals.

Hence, while trapping and relocation might seem like a direct approach, they do not offer a comprehensive solution to controlling bat populations, making it the least effective method in the context of sustainable wildlife management.
