Which of the following is an element of IPM prevention?

• A. Reducing pest access to food, water, and shelter
• B. Relying on chemical sprays only
• C. Waiting for pests to appear
• D. Ignoring sanitation

Answer: (A)

In IPM, prevention starts by making the environment unattractive and inaccessible to pests. Reducing access to food, water, and shelter directly lowers the pests’ ability to feed, survive, and reproduce, which helps keep populations small and manageable over the long term. This is achieved through good sanitation, proper food storage, removing standing water, and sealing entry points—all aimed at eliminating the incentives pests have to invade.

Relying only on chemical sprays misses the preventive aspect and can lead to resistance and recurring problems. Waiting for pests to appear is reactive and allows issues to grow, making control harder. Ignoring sanitation also ignores a major source of attraction and habitat for pests. So the best preventive approach is reducing access to food, water, and shelter.
