FAQ’s:
How does MAC Slay Residual Insecticide 500ml provide long-lasting insect control in cracks and crevices?
MAC Slay Residual Insecticide – Crack & Crevice 500ml delivers powerful, ongoing protection by targeting hidden pests where they live and breed. The advanced residual formula remains effective on treated surfaces for weeks, creating a continuous barrier that kills crawling and flying insects on contact and keeps working long after application. This makes it ideal for areas that are hard to reach, such as cracks, wall voids, behind appliances, vents, and under equipment—precisely where cockroaches, ants, spiders, and other pests hide.
The spray is non-staining, dries quickly, and leaves minimal odour, so it can be safely used in food storage, processing facilities, and residential kitchens.
MPI Type A/B approval means it meets New Zealand’s strict standards for use in environments where food is present, so it’s trusted by pest control professionals and facility managers. Regular application according to label instructions can break the pest lifecycle and prevent re-infestation.

MPI Type A/B approval confirms it is suitable for regulated environments such as food processing, storage, healthcare, and hospitality, provided it is applied according to label directions. The non-staining, fragrance-free formula dries quickly, minimising disruption in kitchens, workplaces, and homes.
