Most Common Household Pests in Louisiana (And How to Prevent Them)
Living in Louisiana has a lot of perks — great food, warm weather, and amazing communities. But that same warm, humid climate also creates the perfect environment for pests. From roaches to ants and spiders, many homeowners deal with unwanted guests at some point during the year.
At Big Easy Pest Control, we specialize in keeping Louisiana homes protected from everyday pests. Here’s a simple guide to the most common pests we see — and what you can do to help prevent them.
Roaches
Roaches are one of the most common pests in Louisiana homes. German roaches are usually found indoors, while larger “palmetto bugs” (American and Smokybrown roaches) often come inside from outdoors. They prefer warm, humid areas like kitchens, bathrooms, and laundry rooms.
Prevention Tips
Keep food sealed and stored properly
Take out trash regularly
Fix moisture issues or leaks
Avoid leaving dirty dishes overnight
If you start seeing roaches during the daytime, that can mean there are more hiding nearby.
Ants
Ants are active nearly year-round in Louisiana. Fire ants, carpenter ants, and odorous house ants are some of the most common types. They’re usually looking for food or water — and once they find it, trails form quickly.
Prevention Tips
Wipe spills and crumbs immediately
Seal cracks and entry points
Keep pet food in sealed containers
Avoid stacking wood or debris near the home
Sometimes ant problems start outdoors and move inward — so professional treatment often works best long-term.
Spiders
Spiders are common across Louisiana homes, especially in garages, attics, and dark corners. While most are harmless, species like the brown recluse or black widow can be a concern.
Prevention Tips
Reduce clutter in storage areas
Vacuum webs regularly
Keep outdoor lighting minimal at night
Seal cracks and gaps
Seeing more spiders can sometimes mean other insects are present — because spiders follow their food source.
Rodents (Mice & Rats)
Cooler months often push rodents indoors, where they may nest in attics, walls, or garages. Signs include droppings, scratching sounds, and gnaw marks.
Prevention Tips
Seal gaps around doors, pipes, and foundations
Keep food sealed
Remove outdoor clutter and debris
Store pet food securely
Rodents can multiply quickly, so early action matters.
Fleas & Ticks
Louisiana’s warm climate allows fleas and ticks to stay active much of the year. Pets and wildlife often bring them into yards — and sometimes indoors.
Prevention Tips
Treat pets regularly
Wash pet bedding
Keep grass trimmed
Reduce shaded, overgrown areas
If you see fleas indoors, there are usually more hiding in carpets or bedding.
When Should I Call a Professional?
DIY products may help temporarily — but they often don’t eliminate pests at the source. If you’re seeing pests regularly, noticing signs of nests or trails, or simply want peace of mind, a professional pest control plan can make a big difference.
