Dethlac began with one man’s fascination with chemistry. In 1959, inventor Roy Archer launched his insecticidal lacquer, marking every can with a small archer symbol that still appears on the can today.
When fire destroyed the factory in 1974 and Roy died months later, his daughters Carolyn and Penelope, still teenagers, took over the business. For the next 50 years they kept the brand going, and it became a fixture on the shelves of Boots, Wilko, B&Q and Amazon.
Now part of IGA Global, Dethlac is growing into a full range of pest control products, with the same values it has always had. More than 10 million households have trusted it for over 65 years.

Doors - Applied around thresholds and door frames,
Dethlac creates a durable, touch-safe chemical shield. It stops invading
ants right at the primary entry zone,
remaining active even after heavy foot traffic.
Window Sills - Dethlac forms an invisible, waterproof lacquer across windowsills.
This long-lasting barrier targets the nervous
system of foraging ants on contact, blocking their favourite
high-level entry points into your home.
Skirting Boards - Acting like an "invisible electric fence" along these common indoor
ant motorways, the dried lacquer provides long-lasting residual contact.
It remains completely active even when you wash the area with heavy household detergents.
Behind and Under Large Kitchen Appliances - Ants flock to these dark, undisturbed zones for food crumbs and moisture.
A light spray on the floor along the back wall creates a durable shield that
kills pests within a few hours of contact.
Cupboards and Food Storage Areas - Applied along the internal baseboards and corners of pantries
or under-sink cupboards, it denies ants access to storage spaces.
It provides a dry, touch-safe boundary that blocks
foraging without contaminating nearby dishes.
Outdoor Spaces (Patios, Concrete, and Gardens) - Applied to hard, non-absorbent outdoor surfaces, Dethlac's unique weatherproof
formula refuses to wash away. It forms a resilient barrier that continues eliminating trailing
ants even after heavy exposure to rain and moisture.
