Spring Ant Invasions in Louisiana: Why They’re Starting Now (And DIY Prevention Tips)
If you’re starting to see ants inside your home in Jefferson Parish, Orleans Parish, or anywhere in the Greater New Orleans area — you’re not alone.
Even though temperatures are still mild, this is the time of year when ant colonies begin expanding and searching for new food sources.
Here’s why it’s happening — and what you can do about it.
Why Ants Start Invading Louisiana Homes in Late Winter
Louisiana’s warm, humid climate allows ant colonies to stay active almost year-round.
As temperatures begin to rise:
Colonies grow
Worker ants search aggressively for food
Rain drives them indoors
Moist soil pushes them toward foundations
The most common ants we see in Louisiana homes include:
Argentine ants
Odorous house ants
Fire ants
Carpenter ants
Once you see a few — there are usually thousands more nearby.
DIY Tips: How to Help Prevent Ants Inside Your Home
If you’re trying to handle it yourself first, here are some simple prevention steps:
1. Seal Entry Points
Check:
Window frames
Door sweeps
Cracks along baseboards
Exterior foundation gaps
Ants only need a tiny opening.
2. Eliminate Moisture
Louisiana humidity makes this critical.
Fix:
Leaky faucets
Dripping AC lines
Standing water near the home
Poor drainage around the foundation
Moisture attracts colonies.
3. Clean Food Sources
Wipe:
Countertops nightly
Pet food areas
Pantry shelves
Under appliances
Ants leave scent trails that attract the rest of the colony.
4. Be Careful With Store-Bought Sprays
Many DIY sprays:
Kill the ants you see
Do NOT eliminate the colony
Cause colonies to split and spread
This is why infestations sometimes get worse after DIY treatments.
When It’s Time to Call a Professional
If:
Ants return after DIY attempts
You see trails daily
You’re seeing multiple areas affected
You suspect carpenter ants (which can damage wood)
It’s usually a sign the colony is established inside walls or under the slab.
