ELI5: Why/How the hell can the worst bugs (fleas, ticks, bedbugs, etc) live for MONTHS with no food and just keep repopulating and repopulating and repopulating even though there's NO nutrition?

As if they're not annoying enough when a wave comes into your house, but even the ones that are starved in empty rooms just fucking stay there forever and fuck like rabbits.

Why and How the fuck can these shitty parasites multiply so damn much even though they have nothing? They're surrounded by poison. All the food they do have has poison on it. Some aren't even near animals or people. They just. Don't. Fucking. Die.

How in the hell are these garbage species so immortal?

These pests have evolved to be very hardy, having built-in survival mechanisms that help them survive. Insects are cold-blooded so they don't need to use energy to keep them warm. Additionally, if it gets cold enough, their metabolism will slow down meaning they can go a long time without eating any food.

Unfortunately these pests have just evolved to survive on such little food and reproduce so quickly. If they didn't, they wouldn't have survived as a species.
