How does temperature influence the effectiveness of fumigation?

• A. Higher temperatures typically decrease fumigation efficacy
• B. Temperature has no effect on fumigation efficacy
• C. Higher temperatures generally improve fumigation efficacy
• D. Temperature only affects the speed of application

Answer: (C)

Higher temperatures generally improve fumigation efficacy because increased heat enhances the penetration of the fumigant into the target area, whether it be soil, structural wood, or another material. Many fumigants are more effective when the ambient temperature is warmer, as higher temperatures can accelerate the diffusion rate of the gas and increase the metabolic activity of pests, leading to a more efficient and thorough eradication. At elevated temperatures, the pests may be more active and vulnerable, and the fumigant molecules move more rapidly, allowing them to reach and penetrate into various harborages and protective environments more effectively. Additionally, many fumigants are designed to vaporize more readily in warmer conditions, which leads to higher concentrations of the gas in the treated environment. While it is important to manage and control temperature conditions during fumigation processes, overall, the thermal conditions can significantly impact the success of pest control efforts, making it crucial for pest management professionals to consider temperature factors during application.
