Expanding Foam Question

[DD716TED]

I have an small area (1" wide x 3 ft) between the wood belly band and concrete block foundation at the base of my siding. I want to seal this point as it could be a point of entry under the house for small rodents.. (None yet).. Question: If I fill this area with the expanding foam that is available at the hardware store, will it keep rodents out or will they chew through it if they want in? Suggestions? Thank you..

I don't see why not? maybe you could shove d-con pellets into the foam before it cures.
