Which statement best reflects why a one-time service is not effective?

• A. It eliminates all pests immediately
• B. It costs more than repeated service
• C. It does not disrupt pest egg cycles; pests return
• D. It is only for commercial properties

Answer: (C)

Understanding why a single service often falls short hinges on pest life cycles. Many pests lay eggs that can survive on a home when a treatment is applied, so even after the adults are killed, eggs remain hidden and later hatch. A one-time treatment may reduce visible pests right after service, but it doesn’t disrupt eggs or the breeding cycle, so pests can come back as soon as those eggs hatch. That’s why ongoing or repeated service is usually needed to keep numbers down and prevent reinfestation. The other ideas aren’t the main reason a one-time service is ineffective: claiming it eliminates all pests immediately ignores the reality that eggs can survive and hatch later; suggesting a higher cost over time isn’t about effectiveness itself; and saying it’s only for commercial properties isn’t true. The key concept is the need to interrupt the pest’s life cycle, not just kill what’s visible at the moment.
