What is a cockroaches' biggest weakness?

What is a cockroaches' biggest weakness? A cockroach's biggest weakness includes several vulnerabilities. They are highly dependent on moisture and cannot survive long without water, so dry environments and fixing leaks is weakness. They have open circulatory system and breathe through spiracles, making them vulnerable to boric acid, diatomaceous earth, and insecticides that damage exoskeleton and dehydrate them. They are attracted to food but have poor ability to resist baits with slow-acting poison that they carry back to nest. Their need for shelter in cracks and crevices makes them vulnerable to sealing entry points and cleaning clutter. They are also vulnerable to cold temperatures, as they are cold-blooded and die in freezing. Their reliance on pheromones for aggregation means disrupting trails can confuse them. Biggest practical weakness for control is their need for water and food and habit of grooming, which makes gel baits and boric acid effective, as they ingest poison while cleaning. Also, they cannot survive without hiding spots, so cleanliness and sealing cracks exploit weakness.
