Oakdale's rural environment makes it an ideal breeding ground for a variety of pests.

Ants are common in homes, kitchens, restaurants, and farms, particularly during the warmer months when they search for food and water. They can be especially troublesome in agricultural settings and food storage areas.

Mice and rats are also prevalent in Oakdale, particularly in agricultural buildings, homes, warehouses, and commercial properties. These rodents cause extensive damage by gnawing on structures, insulation, wires, and crops, while also spreading diseases and contaminating food.

The older homes and wooden structures in Oakdale are vulnerable to termite infestations, which silently cause significant damage to wood and can lead to costly repairs if left unchecked.

Cockroaches are frequently found in kitchens, restaurants, and food-related businesses, where they spread bacteria, contaminate food, and create unsanitary conditions.

While many spiders are harmless, species like the black widow can be dangerous, especially in dark, undisturbed areas such as basements, attics, and storage spaces in homes and businesses.
