Weather plays a significant role in pest infestations in Royal Oak. The city's cold winters often drive pests like rodents indoors in search of warmth and food, leading to increased infestations during these months. Conversely, the warmer and more humid summers create ideal conditions for insects like ants, flies, and cockroaches to thrive. Business owners should be particularly vigilant during seasonal transitions, as pests are more likely to seek shelter and resources inside commercial properties during these times.
