As the vibrant hues of fall settle over St. Louis and the temperatures begin to drop, homeowners might find themselves facing unwelcome guests seeking shelter from the cold. The shift in weather drives various pests indoors, where they can become more than just a nuisance—they can pose health risks and cause property damage. Understanding which pests are most active during this season and how to prevent them is crucial for maintaining a safe and comfortable home.
In this blog post, we’ll explore the top five pests to watch out for in St. Louis as the weather cools down and provide tips on how to protect your home from these intruders.
1. Rodents (Mice and Rats)
Why They’re a Problem in Fall
Rodents are notorious for seeking warm, cozy places to nest as temperatures decline. Homes provide the perfect environment with ample food sources and shelter. In St. Louis, the most common culprits are the house mouse and the Norway rat.
Damage and Health Risks
- Property Damage: Rodents chew on wires, insulation, and structural materials, which can lead to electrical fires and costly repairs.
- Health Risks: They can contaminate food and surfaces with droppings, spreading diseases like Hantavirus and Salmonella.
Signs of Infestation
- Droppings around food packages, drawers, or cupboards.
- Gnaw marks on wires, furniture, or walls.
- Scratching noises in the walls or attic during nighttime.
2. Spiders
Why They’re a Problem in Fall
As insects move indoors to escape the cold, spiders follow their food sources. St. Louis is home to various spider species, including the brown recluse and black widow, which are venomous.
Damage and Health Risks
- Bites: While most spiders are harmless, bites from venomous species can cause serious health issues.
- Allergic Reactions: Some individuals may experience allergic reactions to spider bites.
Signs of Infestation
- Spider webs in corners, basements, or garages.
- Sightings of spiders crawling on walls or floors.
- Egg sacs attached to surfaces.
3. Cockroaches
Why They’re a Problem in Fall
Cockroaches thrive in warm, humid environments. As outdoor temperatures drop, they migrate indoors in search of warmth and food, making fall a peak time for infestations.
Damage and Health Risks
- Allergens: Cockroach droppings and shed skins can trigger asthma and allergies.
- Disease Spread: They can carry bacteria like E. coli and Salmonella on their bodies, contaminating food and surfaces.
Signs of Infestation
- Musty odors emanating from hidden areas.
- Droppings resembling coffee grounds or pepper.
- Shed skins or egg cases in hidden crevices.
4. Stink Bugs
Why They’re a Problem in Fall
Stink bugs seek shelter in homes to hibernate over the winter. They enter through cracks and gaps, congregating in warm areas of the house.
Damage and Health Risks
- Odor: When disturbed or crushed, stink bugs release a foul-smelling odor.
- Plant Damage: While they don’t harm humans, they can damage houseplants and garden vegetation.
Signs of Infestation
- Sightings of brown, shield-shaped bugs around windows or light fixtures.
- A noticeable increase in indoor insects during sunny days.
5. Ants
Why They’re a Problem in Fall
Ant colonies seek new food sources as natural supplies dwindle. Your home becomes an attractive destination, especially the kitchen and pantry areas.
Damage and Health Risks
- Contamination: Ants can contaminate food products.
- Structural Damage: Carpenter ants, in particular, can damage wood structures by hollowing them out for nesting.
Signs of Infestation
- Trails of ants along floors, walls, or countertops.
- Small piles of dirt or wood shavings indicating nesting sites.
- Winged ants emerging indoors, signaling a mature colony.
Prevention Tips for Homeowners
- Seal Entry Points: Inspect and seal cracks, gaps, and holes around your home’s exterior, including doors, windows, and utility penetrations.
- Maintain Cleanliness: Keep kitchens and dining areas clean. Store food in airtight containers and dispose of garbage regularly.
- Reduce Moisture: Fix leaky pipes and use dehumidifiers in damp areas like basements and crawl spaces.
- Trim Vegetation: Keep trees and shrubs trimmed away from the house to reduce pest bridges into your home.
- Regular Inspections: Conduct regular inspections of your home for signs of pests or potential entry points.
