Which of the following is a recommended method to minimize cockroach infestation?

Sealing cracks and repairing water leaks is recommended because cockroaches often enter structures through small openings and thrive in environments where there is moisture. By sealing gaps in walls, around pipes, and in doorways, you create a physical barrier that prevents these pests from accessing your space. Additionally, fixing water leaks reduces moisture, which is crucial for cockroach survival. Maintaining a dry environment disrupts their habitat and feeding grounds, ultimately helping to minimize their population.

Leaving food out in open containers, maintaining high humidity levels, and using chemical repellents frequently do not effectively control or prevent cockroach infestations. In fact, these practices can attract cockroaches and provide them with the resources they need to thrive.
