Spotting wasp larvae moving inside their nest might be fascinating on video, but when it's happening on your property—it's a whole different story. While most people focus on adult wasps buzzing around, it's easy to forget that inside those papery nests is an entire colony of developing insects. And those larvae? They're the next generation ready to make your home their home.
Let's break down why wasp larvae are more than just an unsettling sight—and why professional pest control matters.
Understanding Wasp Life Cycles
Wasps, like many insects, have distinct life stages:
1️⃣ Egg
2️⃣ Larva
3️⃣ Pupa
4️⃣ Adult
After an egg hatches, the larva spends several days eating, growing, and eventually forming a cocoon to transition into its adult form. During the larval stage, these tiny, wriggling creatures are completely dependent on the worker wasps to feed and protect them.
If you're seeing larvae actively moving, it means that nest is thriving—and trouble may be on the way.
Why Are Wasp Larvae a Problem?
➡ Sign of a Growing Nest - More larvae = more adult wasps soon. The larger the nest gets, the greater the risk of aggressive behavior from the colony.
➡ Hidden Nests - Often tucked in attic spaces, wall voids, or eaves, these nests can expand unnoticed until someone accidentally disturbs them.
➡ Protective Adults - Wasps will fiercely defend their developing larvae, increasing your chances of being stung just by getting too close.
Where Do We Usually Find Them?
🛠️ Behind walls
🛠️ Under roof overhangs
🛠️ Inside sheds or garages
🛠️ Hidden in crawlspaces or attics
In some cases, we've even discovered active wasp nests inside exterior vents or tucked neatly behind shutters.
Leave It to the Pros
Dealing with wasps—especially nests with visible larvae—is not a DIY project. Disturbing an active nest without proper equipment and knowledge can lead to dangerous stings, especially for those allergic to wasp venom.
At PestNation, we don't just spray and hope for the best—we locate, identify, and safely remove nests to ensure the entire colony is handled, larvae included.
