Which of the following is a disadvantage of glue boards for rodent control?

• A. Easy to Use
• B. Nontoxic
• C. Can Also Monitor Insects
• D. Affected by Dust and Wetness

Answer: (D)

Glue boards trap rodents by relying on a sticky adhesive. Their effectiveness depends on keeping that adhesive tacky and in good contact with the rodent. Dust or debris on the board or on the rodent’s fur reduces contact and prevents sticking, so the rodent may not be captured. Moisture or wet conditions can soften or wash away the adhesive, eliminating the bond and allowing the animal to escape. Because environmental conditions directly undermine how well glue boards work, this is the key disadvantage. The other points describe benefits—being easy to use, non-toxic, or capable of monitoring insects in some settings—so they don’t represent drawbacks in this context.
