Ground squirrels under the house are a structural risk, since their burrows can undermine the foundation, and the fix is trapping then sealing. Ground squirrels dig under slabs and foundations, so you want them out and the space sealed. Here is what to do.
- Burrows under the house can undermine the foundation.
- Trapping near the burrow is the removal method.
- Seal the space under the house after removal.
- Ground squirrels live in colonies, so expect several.
Why It Matters
Ground squirrel burrows under a slab or foundation can cause settling over time. The damage is structural, so this is worth fixing promptly.
Trap the Colony
Place traps near the active burrow entrances under the house, baited with nuts or peanut butter. Ground squirrels live in colonies, so be prepared to catch several.
Seal the Space
Once the squirrels are out, seal the opening under the house with hardware cloth or a buried barrier, so another colony cannot move in.
Remove Attractants
Remove food sources like spilled bird seed and fallen fruit, and keep ground cover trimmed. Less food and cover means the colony moves elsewhere. The DIY vs. pro quiz tells you in five questions whether this one is a job for you or for a licensed pro.

Yes, they live in colonies, so where there is one there are usually several. Control the whole colony.
