I was curious why wool mulch would deter pests. So, I went looking for a picture. (My #wool would fall under the "fine" category.) So, crawling through wool mulch would feel scaly/scratchy to bugs/slugs and they'd probably prefer to try a different/unmulched plant first. Wool mulch also holds in moisture and keeps the soil cooler, which helps the plants grow larger faster. Wool is a valuable mulch!
