I get that lots of people these days want to use DoTerra or oils or whatever shit instead of the big guns, but I don’t have time or patience to test everything out and see what actually works (which I’ve spent too much of my life doing). We have tons of black widows and wolf spiders where I live and having a baby or a dog bitten is not an option!
Get a statue of a big owl like this one and put it on a post in your yard... that'll keep them away.
No clue if it would work, but they may be afraid of owls or hawks. Can always try something like this: https://www.amazon.com/Gardeneer-Dalen-Natural-Scarecrow-Horned/dp/B00002N8HZ/ref=sr_1_4?ie=UTF8&qid=1472505694&sr=8-4&keywords=fake+owl+for+garden
