Final answer:
The reason that does not apply to the necessity of controlling pest infestations is that 'They tend to be overlooked by loyal customers who know the food is good.' Pest management is crucial due to the risks of food contamination and the broad economic and health implications.
Step-by-step explanation:
The question asks for a reason that pest infestations must be controlled that does not apply. Pest infestations must be controlled for several important reasons, but not because 'They tend to be overlooked by loyal customers who know the food is good.' This reason is incorrect because even loyal customers are likely to be concerned by pest infestations, which can lead to a loss of business reputation and can have serious health implications due to food contamination.
On the other hand, it is true that pest infestations cause physical, chemical, and biological contaminations of foods, which can have severe health consequences for consumers. Pest infestations are indeed disgusting and can lead to a loss of business and revenue, as customers are likely to be repelled by the presence of pests. Moreover, pests are one of the first things inspectors look for and can lead to the shutdown of a business if not managed properly, emphasizing the importance of controlling pest populations.
Pests can cause damage to agriculture, public health, and other sectors, and are often controlled by pesticides, which have their own set of problems, including the risk of evolving pest resistance and non-target impacts. Consequently, alternative pest management methods, such as biological controls using natural predators and parasites of pests, have been found to be effective in some studies.
