What are the human health concerns associated with pharaoh ants?

Pharaoh ants present notable human health concerns primarily because they are known to feed on organic matter, including items such as open wounds and the mouths of infants. This behavior can lead to serious health implications since it increases the risk of transmitting bacteria and pathogens. Their presence in hospitals particularly raises alarm, as they can contaminate surgical wounds and medical supplies, potentially causing postoperative infections or other serious health issues.

While other options may involve some aspects related to pest concerns, the unique feeding habits of pharaoh ants pose direct risks to vulnerable populations, particularly infants who are more likely to have open mouths or skin. This feeding behavior underscores the importance of effective pest management strategies, especially in settings like homes and healthcare facilities where health risks are heightened.
