Pre-spray preparation is the foundation of effective pest control and operational safety.
Inspect for pest entry points: Conduct a thorough check to identify common access routes for pests (ants, cockroaches, mosquitoes, etc.), including wall cracks, gaps around door/window frames, utility line penetrations, foundation joints, and areas near garbage bins. Mark these spots to ensure targeted spraying later.
Clear surrounding debris: Promptly remove fallen leaves, dead branches, stacked cartons, or waste around the property. Drain standing water from flower pot saucers and gutters—these environments breed and shelter pests, so cleaning them eliminates breeding grounds and enhances the insecticide’s effectiveness.
Prepare protective gear: Disposable gloves, a protective mask, and long-sleeved clothing are essential to avoid direct skin contact with the chemical or inhalation of atomized particles. Goggles are recommended for spraying near the face. Additionally, cover or move outdoor furniture, children’s toys, and pet supplies in advance to prevent contamination.
Follow these steps to ensure precise, effective application:
Select the right time: Opt for windless mornings or evenings. These periods avoid high temperatures (which accelerate chemical volatilization) and strong winds (which cause spray drift). These timeframes also coincide with increased pest activity, elevating the efficiency of pest control.Avoid rainy days and midday intense sunlight—rain washes away the insecticide, while direct sun decomposes it, rendering it ineffective.
Spray at the correct distance and target key areas: Maintain a 20–30cm distance from surfaces to ensure the insecticide forms a uniform mist film. This prevents surface damage from over-concentration (when too close) and uneven coverage (when too far). Focus on key entry points: door/window gaps, foundations, and utility line interfaces. Targeted spraying creates a comprehensive protective barrier, blocking pests at the source for efficient, long-lasting results.
Make safety a top priority to protect yourself, your loved ones, and the surrounding environment:
Wear essential protective gear: Gloves isolate the insecticide from direct skin contact, preventing irritation or allergic reactions.A mask prevents the inhalation of atomized particles, lowering the risk of respiratory discomfort. These measures form the first line of defense for safe operation.
Avoid sensitive areas: Never spray near food, water sources, children’s activity zones, or pet areas. Insecticide contamination of food or water can lead to accidental ingestion and poisoning.Children (due to curiosity) and pets (due to licking/touching surfaces) are particularly vulnerable to residual chemicals—strictly avoiding these areas ensures pest control does not compromise health.
Proper post-application care ensures long-term effectiveness and safety:
Ventilate thoroughly: Allow 4–6 hours of ventilation after spraying to dissipate residual insecticide fumes. Keep doors and windows fully open to prevent chemical odor accumulation in enclosed spaces, minimizing inhalation risks—especially for the elderly, children, and other vulnerable groups. Resume normal activities only once the odor has completely disappeared.
Re-spray after rain: Rain washes away the protective chemical film, leaving entry points unguarded. Re-spray promptly after rainfall to restore the barrier and prevent pest re-invasion.
Maintain regular protection: During peak pest seasons, re-spray every 2–4 weeks; during non-peak periods, re-spray every 1–2 months. Focus on re-coating original treated areas to reinforce the protective barrier, ensuring consistent long-term pest prevention.
