Sap is harmless, but it can be unsightly. You can remove it by:
- Gently scraping it off
- Using warm, soapy water or a specialized cleaner
Be careful not to damage the fence surface, especially if it’s painted or treated.
5. Insect Egg Clusters (Other Species)
While praying mantis egg cases are the most well-known, other insects also lay eggs in clusters that can appear as hardened clumps.
These might include:
- Moths
- Beetles
- Certain types of flies
Their appearance can vary widely, but they’re often smaller and less structured than mantis oothecae.
What You Should Do
If you’re unsure, it’s best to avoid disturbing the cluster until you can identify it. Taking a photo and comparing it to reliable sources—or consulting a local gardening center—can help.
