I've had a lot of luck doing an essential oil blend spray. I use citronella, peppermint, rosemary, lemongrass, cedarwood, tea tree, eucalyptus, lavender, purification and animals scents repel. All by young living essential oils. Best results I've had and I live in Florida
i use ultrashield & ultrashield green. these work great, including the "green" version...most citrus types of fly spray don't work. smartpak's bug off spray is good to, as well as the absorbine citronella spray.
