Which of the following is a recommended practice for preventing pest infestations?

Sealing cracks and crevices in structures is a recommended practice for preventing pest infestations because it helps to eliminate entry points that pests can use to access the interior of buildings. Many common pests, such as ants, roaches, and rodents, can enter through tiny openings in walls, foundations, and around windows and doors. By effectively sealing these gaps, property owners create a formidable barrier that significantly reduces the likelihood of pests finding a way inside.

In contrast, other options can inadvertently encourage pest problems. For instance, regularly watering gardens can promote the growth of vegetation that attracts pests, while leaving food exposed provides an easy food source that can draw pests into living areas. Utilizing chemical sprays often is not a long-term solution and may lead to resistance among pest populations, as well as potential health risks for humans and pets. Therefore, sealing cracks and crevices is a proactive and effective pest management strategy.
