If you’ve found an old wasp nest tucked into the eaves of your home or spotted one clinging to a corner of your porch, you might be wondering: Do paper wasps come back to the same spot every year?
Here in Louisiana, with our warm, humid weather, it’s not unusual to find wasp nests popping up in the exact locations year after year. But is it the same wasps rebuilding in that spot, or just new ones with the same idea?
Let’s clear that up and talk about why paper wasps build nests where they do, whether they reuse them, and what you can do to keep them from coming back.
Key Takeaways
• Paper wasps do not reuse old nests, but new queens may build new nests near previous sites.
• Paper wasp nests are most often found in eaves, overhangs, and crevices that offer shelter from rain and predators.
• Old nests are abandoned after a season and do not house wasps over winter.
• LaJaunie’s Pest Control offers safe, effective wasp nest removal and prevention across South Louisiana.
Do Paper Wasps Come Back to the Same Nest?
No, paper wasps do not reuse the same nest. Once winter hits in Louisiana, the colony dies off, leaving the old nest behind. It becomes brittle and empty, just a shell of what it once was.
But here’s the kicker: new queens that survive the winter will often return to the same general area. That means if your eaves or porch were attractive to wasps last year, they could be on a new queen’s radar this year.
While they don’t return to the same old nest, they often return to the exact nest location.
What Happens to the Nest Over Winter?
Once we hit late summer or early fall, the paper wasp colony begins to die off. The only ones that survive are the new queens, who leave the nest and find a place to hibernate, like under bark, in logs, or even tucked into sheltered parts of homes.
The old nest itself gets abandoned and never reused. Paper wasps won’t lay eggs or raise larvae in it again. That’s because the structure weakens over time, and it’s easier (and safer) for wasps to build a new nest from scratch.
Where Do Paper Wasps Build Nests?
If you’ve lived in Southern Louisiana for a while, you’ve probably noticed where paper wasps like to set up shop:
• Eaves of homes
• Overhangs
• Porch ceilings
• Garage rafters
• Behind shutters
• Inside sheds or barns
These areas offer protection from the elements and predators, making them ideal real estate for a wasp queen starting fresh.
If you’re finding wasp nests in the same place every spring, it’s not a coincidence. It’s a sign that the location checks all the boxes: dry, shaded, and inaccessible to predators.
Why Do Wasps Choose the Same Locations?
It comes down to pheromones and shelter. The smell of an old nest may act as a subtle signal that this is a good place to build. Add in the safety and cover of an eave or crevice, and you’ve got an ideal nest site.
Even though the old nest isn’t reused, the area around it still attracts new queens.
This is especially common in Louisiana’s mild winters and long warm seasons. In areas like Houma, Thibodaux, and New Orleans, it’s not uncommon to find paper wasp nests reappearing in early spring.
Paper wasps, like many other species of wasps, prefer areas close to a food source, such as flowering plants or gardens. These locations offer nectar for adults and insects for their larvae. As beneficial pollinators, adult wasps play a role in local ecosystems, even though most folks would rather keep them away from the porch.
When a spot has already proven to support a thriving colony, it increases the chances that homeowners will see new nests nearby. Even a diy attempt at wasp control can leave behind cues that encourage future nesting if the site isn’t thoroughly cleaned or treated by a professional.
Are Paper Wasps Aggressive?
Paper wasps are more laid-back compared to yellow jackets or bald-faced hornets, but they will defend their wasp nest if you get too close.
Most stings happen when someone accidentally disturbs a nest. The sting can be painful, and for those with allergies, it can be even dangerous.
Unlike honey bees, paper wasps can sting more than once. That’s why safe wasp nest removal is essential, especially if nests are close to entryways or high-traffic areas.
That said, aggressiveness varies by type of wasp. Some species of wasps are more defensive than others. A trained entomologist or exterminator can assess the risk if you’re unsure what kind you’re dealing with.
Wasps near the ground, such as those found in ground nests like those of yellow jackets, are often more aggressive than those in aerial nests. Homeowners should never try to knock down a nest during the day or without protection.
Even a small infestation can quickly turn dangerous when disturbed. Getting too close can result in multiple wasp stings, especially if the colony sees you as a threat. If you’re seeing a lot of activity, it’s best to call a professional.
What Should You Do With an Old Nest?
If you find an abandoned nest, you can knock it down yourself if you’re comfortable. But be sure it’s truly inactive; there should be no worker wasps buzzing in or out. Even if it’s empty, removing it helps discourage new queens from choosing that exact nest location again.
If the nest is up high, in a tricky spot, or you’re unsure whether it’s active, don’t take the risk. Call a professional pest control service, such as LaJaunie’s.
Old nests can harbor leftover scent trails or pheromones that signal a good spot to future queens. Simply leaving it up increases the chances of repeat infestation in spring. Many homeowners attempt DIY removal, but without the right safety gear and expertise, it can backfire, especially with active nests or less visible ones, such as ground nests.
If you’re unsure what species of wasp built the nest, consult a local entomologist or call an experienced exterminator who can identify whether you’re dealing with yellow jacket nests, paper wasps, or something else entirely. Effective pest management involves not only removing the nest but also addressing the factors that initially made the site appealing.
How To Prevent Wasps From Returning
If you’ve had paper wasps in the past, the best way to keep them from coming back is to make your home less appealing:
• Seal small cracks and crevices around rooflines and attic vents
• Remove any old, abandoned nests.
• Spray natural deterrents, such as peppermint oil, in areas where nests have previously formed.
• Regularly inspect eaves and overhangs in early spring.
• Consider using wasp traps in areas where the problem is most prevalent.
Most importantly, have your home professionally treated during early spring when new queens begin scouting nest sites.

FAQs
Do wasps return to the same place every year?
Yes, but not the exact nest. New queens often build in the same area where nests were found before.
Will wasps reuse an old nest?
No. Paper wasps never reuse the same nest. Once it’s abandoned in winter, it stays that way.
How do you know if a wasp nest is active?
Look for movement, such as worker wasps flying in and out or clustering around the nest. An inactive nest will look dry and brittle.
When should I remove a wasp nest?
Early morning or late evening, when wasps are less active. For high-up nests, call a pest control company.
What time of year are wasps most active in Louisiana?
Paper wasps in Louisiana are most active from late spring through early fall, when warm weather supports colony growth. New queens start nest building in early spring.
