Sitting at the confluence of the Mississippi and Missouri Rivers, St. Louis is all about high heat and humidity during summer, rainfall in spring, and freeze-thaw cycles in winter. Pest problems here vary by season and neighborhoods. While older homes with stone foundations in Soulard, Tower Grove South, Benton Park, and The Hill have repeat infestations, newer properties aren’t safe either.
No matter the infestation and the extent of pest pressure, you have to seek professional help. Companies like Pointe Pest Control specialize in residential services across St. Louis, and you can get prompt assistance for new spikes, often within one to two days. Below is an overview of persistent household pests in the city.
- German Cockroaches: Most South City apartments, bigger flats, and duplexes in St. Louis have shared plumbing walls and moist basements and kitchens. Rental properties have a high tenant turnover, and all of these factors make German roaches a real problem. Many homeowners continue to try DIY remedies and steps, which often drive these pests deeper into wall voids and new areas. Also, treating just one part of the house rarely helps.
- Rodents: Norway rats are commonly seen near the Mississippi Riverfront and rail lines in Downtown and North City. House mice, on the contrary, can be found across residential zones. Rodents can use all kinds of gaps and holes, and even utility penetrations in older buildings are used as entry points. Even during winter, rodent cycles don’t end but move indoors. In busy zones of St. Louis, rats and mice find considerable food sources, ensuring ongoing infestations.
- Ants: Odorous house ants are regular invaders in Missouri and flourish well in humid soil. Activity often increases after rain, especially in spring. There are also pavement ants, which are seen in driveways and sidewalks, especially in neighborhoods with aging concrete. Carpenter ants aren’t unusual either, and most infest homes that have wooden frames and structures damaged by moisture. Most indoor sprays are inactive, and because ants can be seasonal, ongoing efforts are a must.
- Termites: Regardless of where you are located in the St. Louis metro, the chances are high that you have heard other homeowners talk about eastern subterranean termites. The soil of the region is heavy in clay, which allows termites to tunnel easily. If wooden structures of your home touch the soil, the chances of infestations can be considerably higher. Termites are one of the toughest pests to catch, which is why inspections are a must every year. Once the damage is done, repairs can be extremely expensive.
- Spiders and Other Pests: Common persistent pests in the region include brown recluse spiders, cellar spiders, and centipedes. Brown recluse activity increases significantly in homes with cardboard storage and in areas like basements, closets, and garages where foot traffic is low. More spiders mean more insects, which is why it is important to check for other hidden infestations.

Because St. Louis is a big city with diverse and ongoing pest issues, it is wise to think beyond DIY. When you try sprays or other supermarket products, you are only treating visible or surface problems, and even if you get some relief, the results won’t last. Rather than looking for signs of infestation every two to three weeks, consider hiring help. Call a pest control company in St. Louis for regular inspections to find undetected issues that need work. Technicians can create an annual plan that includes assessments and treatments for prevention, designed for your home’s location, neighborhood issues, and routine pest problems. Don’t step away from discussing their methods, which have to be in line with IPM.
