This aerosol canister is formulated for use inside a Country Vet automatic metered dispenser, releasing a fine mist at set intervals to control flying insects in enclosed spaces. The active ingredients are pyrethrins paired with piperonyl butoxide, a combination intended to knock down and repel house flies, mosquitoes, gnats and small flying moths. It is suited to barns, stables, dairies, kennels and similar premises, as well as commercial spaces such as food processing plants and offices when positioned away from exposed food. The canister carries a light lemon fragrance and is built to supply a full dispensing cycle from a single fill. Setup involves mounting the dispenser at height with good airflow and loading the canister so the valve aligns with the dispenser mechanism; batteries for the dispenser are purchased separately. The label calls for indoor use only and specifies clearance distances from food handling areas and from children.
