How do ants build immunity against pesticides?

What process occurred in the ant population that explains this change in the ant population?

Ants build immunity why? Because of adaptation

Ants Building Immunity Against Pesticides

Ants, like many other living organisms, have the ability to adapt to changes in their environment in order to survive. When June sprayed her bonsai with pesticide to kill the ants, some of the ants were able to survive the initial application. These surviving ants carried genes that made them resistant to the pesticide, allowing them to reproduce and pass on this resistance to their offspring.

Over time, as June attempted to reapply the pesticide, she found that it was now ineffective against the offspring of the ants. This is because the ant population had developed immunity to the pesticide through a process known as adaptation. This process involves the survival and reproduction of individuals with traits that help them survive in a changing environment.

With each generation, the ants that were more resistant to the pesticide were more likely to survive and pass on their resistance genes to their offspring. This resulted in a population of ants that had built immunity against the pesticide, making it ineffective in controlling their population.
