What is a common sign of successful fumigation?

A common sign of successful fumigation is the absence of any signs of pest activity after the area has been aerated. This indicates that the fumigant was effective in eliminating the targeted pests during the treatment process. Successful fumigation means that the pesticide not only penetrated the intended areas but adequately disrupted the life cycle of the pests, ensuring that they do not return. This aligns with the goal of fumigation, which is to eradicate pest infestations completely.

Visible residues remaining in the space could potentially indicate improper application or that the fumigant was not fully absorbed or effective, while the return of pests shortly after treatment points to an unsuccessful fumigation, confirming that the procedure did not eliminate the pests as intended. Similarly, an increase in pest populations is a clear sign that the fumigation did not take place effectively. Thus, the absence of pest activity post-aeration serves as the definitive indicator of successful execution of fumigation practices.
