Yes, vinegar works. with some dish washing soap.
My wife used this combo.
1 Gal White Vinegar
1/2 Cup Salt
1 Tsp of Dawn.
If you have a well for drinking water you have to be careful about using weed killers, throwing away oil, paint and other chemicals that could get into your water system.
My son has a well and horses so water quality is important.
You can also make bug sprays. Check the internet.
