Anyone who’s spent time in a barn knows flies aren’t just a nuisance—they’re a real problem that affects animal health and your peace of mind. This Country Vet fly spray refill keeps your automatic dispensers working around the clock, releasing measured doses of protection without you having to remember to spray manually every few hours.
What You’re Getting
- Ready-to-use 6.4 oz refill canister that drops right into your existing dispenser
- Timed release formula that keeps working when you’re busy with other chores
- Effective against flies, mosquitoes, and other flying pests that bother livestock
- Each case includes 12 canisters so you’ve got backup when you need it
Built for Real Farm Work
This refill works with Country Vet automatic metered dispensers that you’ll typically find mounted in dairy barns, horse stables, livestock buildings, and other areas where animals gather. These dispensers help maintain consistent fly control in milking parlors, feed areas, and anywhere else you need to keep flying insects under control without constant manual spraying.
Made to Last
The aerosol formula is designed to work reliably in farm conditions, from hot summer days to humid barn environments. Each canister delivers consistent spray patterns through thousands of automatic releases, so you’re not dealing with clogged nozzles or weak spray when you need protection most.
Good to Know
Swapping out an empty canister takes just a few seconds—pull out the old one and click in the new refill. Make sure your dispenser settings match your pest pressure and room size. During peak fly season, you might want to adjust the timing for more frequent releases.
