Workers found four radioactive wasp nests at the Savannah River Site in South Carolina in July 2025. Officials said the nests were contaminated but reported no contamination in the surrounding ground and no impact to workers, the public, or the environment. A contamination reading for a nest is not a measurement of anyone’s radiation dose, and the precise route by which radioactive material reached the nests remains unexplained.
The discovery was made during routine radiological monitoring at an active federal nuclear site near Aiken. The first nest was reported to have contamination greater than ten times the regulatory total-contamination values; officials attributed it to legacy contamination, while a watchdog criticized the lack of detail about its source.
Key takeaways
- Workers found the first nest on July 3, 2025, in the F-Area Tank Farm at the Savannah River Site; three more were reported by July 31.
- The first nest was reported above ten times the regulatory total-contamination values. That describes contamination on the nest, not a human dose.
- According to the DOE report as recounted by news outlets, officials characterized the finding as onsite legacy radioactive contamination and said it was not related to a loss of contamination control.
- Officials reported no contamination in the surrounding ground and no impact to workers, the environment, or the public.
- The exact radionuclides, wasp species, and pathway to the nest material were not disclosed in the reporting reviewed.
Where was the radioactive wasp nest found?
The first radioactive wasp nest was detected on July 3, 2025, at the F-Area Tank Farm of the Savannah River Site near Aiken, South Carolina. Workers performing routine radiological monitoring found it near tanks used to store liquid nuclear waste.
The Savannah River Site covers about 310 square miles and is an active federal facility, not an abandoned public area. It opened in the early 1950s to manufacture plutonium for nuclear weapons and also produced tritium. Reporting describes a shift in 1992 toward cleanup, nuclear-material management, and research. The site’s official history and current mission information provides broader context.

What happened to the nests?
Workers sprayed the first nest, removed it, and disposed of it as radiological waste. No wasps were found in that nest. The area was secured and surveyed; officials reported no contamination in the surrounding ground.
Three additional nests were found during routine work by July 31, bringing the reported total to four in the F Tank Farm. The site contractor said individual insects found in the additional nests had lower contamination levels than the nests. The count was reported by ABC News. The reporting reviewed for this article does not establish whether more nests were found later.
| Question | What reporting says |
|---|---|
| Where were the nests? | In the F Tank Farm at the Savannah River Site, near Aiken, South Carolina. |
| When were they found? | The first nest was detected July 3, 2025; three more had been reported by July 31. |
| How many were reported? | Four by July 31, 2025. |
| What happened to the first nest? | Workers sprayed and removed it, then disposed of it as radiological waste. |
| Were wasps found in the first nest? | No. |
Were the wasps radioactive?
The reporting describes radioactive contamination in the nests, not a new species of radioactive or mutant wasp. No wasps were found in the first nest, and the available coverage does not establish that the insects themselves became permanently radioactive.
The wasp species and the materials used to build the nests were not identified. Do not infer a specific route from the possibility that some wasps use dirt or other materials: the pathway at the Savannah River Site remains unknown.

What does “more than 10 times the regulatory values” mean?
The first nest was reported to have contamination greater than ten times the regulatory total-contamination values. This is a comparison about contamination measured on the nest, not a measurement of a worker’s or member of the public’s whole-body dose. The complete measurement record and radionuclide identification were not available in the reviewed reporting, so the figure cannot be used here to calculate an individual dose.
Surface-contamination requirements depend on the applicable radionuclide category and measurement context. Without the specific radionuclides and full measurement details, a more precise technical comparison would be misleading.
Was the radioactive wasp nest dangerous?
Officials reported no impact to workers, the environment, or the public, and said the surrounding ground was not contaminated. The nests were inside a controlled nuclear facility, and site personnel removed them as radiological waste. These official findings do not establish that every possible pathway was ruled out.
The contamination reading and the reported absence of impacts describe different things: contamination detected in nest material does not by itself establish that a person received a dose. Officials said wasps generally travel only a few hundred yards, and the nests were within the site. The report’s findings should be understood as officials’ assessment of this incident, not a general claim that radioactive contamination is harmless.

How did a wasp nest become radioactive?
The exact pathway is unknown. The DOE report, as recounted by news outlets, characterized the nest as onsite legacy radioactive contamination associated with historic operations and said it was not related to a loss of contamination control. The report also said the ground and surrounding area had no contamination. These are attributed official statements, not an independently established account of every possible pathway.
Tom Clements, executive director of Savannah River Site Watch, criticized the lack of explanation about where the contamination came from and whether another nest or a tank leak could be involved. His concern is a watchdog’s criticism, not evidence that a leak occurred. The Associated Press report describes the official account and the unresolved questions.
What remains unknown about the radioactive nests?
| Unknown | What reporting establishes |
|---|---|
| Wasp species | The available reporting does not identify it. |
| Radionuclides | The reporting reviewed does not disclose the complete radionuclide identification. |
| Contamination pathway | Officials cited legacy contamination, but the precise route to the nests was not explained. |
| Whether there were more nests | Four were reported by July 31, 2025; later totals are not established in the reporting reviewed. |
| Full measurement record | The available reports do not provide details sufficient to calculate a public dose from the contamination comparison. |
Is the Savannah River Site dangerous?
The Savannah River Site is an active federal facility that handles nuclear materials and radioactive waste, with areas subject to controlled access and radiological procedures. It should not be treated as an abandoned public recreation area. For this incident, officials reported no impact to workers, the environment, or the public and no contamination in the surrounding ground.
The incident illustrates why routine monitoring and controlled waste procedures matter at a former weapons-production site. Workers removed the nests as radiological waste. Officials attributed the finding to legacy contamination, while the precise pathway remained unexplained and a watchdog questioned whether the account was complete.
