Residual Spraying
Residual spraying in Singapore is the application of long-lasting insecticide films on walls, skirting and pest harbourage points to kill crawling insects on contact for weeks. It is designed for restaurants, kitchens, storage rooms and homes that need continuous protection against cockroaches, ants and other surface-active pests between service visits.
Residual spraying applies insecticides to surfaces where pests travel or rest, providing ongoing protection for weeks after application. This proven method creates a protective barrier that continues working long after the initial treatment.
How Residual Spraying Works
A liquid insecticide is applied to surfaces using compression or motorised sprayers. The chemical bonds to the surface and remains active for an extended period (typically 4-12 weeks depending on formulation and conditions). When pests walk across treated surfaces, they pick up the insecticide and are eliminated.
