Sticky traps should be placed in which of the following areas for better results with crawling insects?

1. On ceilings and high shelves

2. Under appliances and in corners

3. In open sunny areas

4. In the yard

The correct answer is: Under appliances and in corners

For optimal results with crawling insects, it is most effective to place sticky traps under appliances and in corners. Crawling insects, such as ants, cockroaches, and spiders, often travel along surfaces close to the ground and seek shelter in dark, hidden spaces. Areas under appliances like refrigerators and stoves provide the ideal environment since these locations are less disturbed and frequently frequented by crawling insects looking for food, moisture, or nesting sites. Additionally, corners tend to accumulate debris and offer dark spaces where these insects may hide or traverse. Other placements, such as on ceilings and high shelves, are less effective because many crawling insects do not typically inhabit those elevated areas. Placing traps in open sunny areas is not advantageous, as many crawling insects prefer cooler, shaded environments. Positioning traps in the yard can miss the target if the objective is to monitor indoor infestations, as this area is not where most crawling pests congregate indoors. Therefore, the recommendation for placement under appliances and in corners is strategic for capturing more crawling insects effectively.
