Absolutely! Rosemary, Lavender, and Basil also work in that regard with some pests too.

There’s also trap plants you can use to lure certain pests away from the plants you care more about.

For example, I use bush beans for spider mites. By keeping the beans near my crop, if spider mites make it into the greenhouses, they typically go for the beans first. So if I see mites on the beans, I can then take preventative measure to protect my crop.
