To use Hit Black Spray 700ml effectively, shake the can well before each use. Hold the can upright and spray directly onto crawling insects from a distance of 15-20 cm for immediate kill. For areas where pests hide, such as cracks, crevices, under sinks, and behind appliances, spray thoroughly but avoid oversaturation. Ensure the area is well-ventilated during and after spraying. Do not spray on food or food contact surfaces.

When used as directed, Hit Black Spray 700ml is generally safe. However, direct exposure may cause mild irritation to skin or eyes. Inhalation of high concentrations in poorly ventilated areas may cause respiratory discomfort. Always use Hit Black Spray 700ml in a well-ventilated space and avoid direct contact with skin and eyes. If irritation occurs, wash affected areas thoroughly and seek medical attention if symptoms persist.
