Ever spotted a trail of ants marching into your kitchen like they own the place? It’s not just annoying – it’s an invasion. That’s where Dethlac comes in, a household favourite since the 1960s. But how exactly does it work? Why do ants die when they touch it? Let’s break it down simply.

What Makes Dethlac Work?

Dethlac is more than just an insect spray – it’s powered by synthetic pyrethroids, clever compounds modelled after a natural insect killer found in chrysanthemum flowers. These synthetic versions are engineered to last longer and hit harder.

One of the most powerful ingredients in Dethlac is deltamethrin, a chemical that targets the ant’s nervous system. Once ants come into contact with it, either wet or dry, their nerves start misfiring. They can’t move properly, they twitch, get paralyzed, and eventually, they die. Fast.

How Fast Does It Kill?

• Direct contact: If an ant touches the wet spray, it can start showing symptoms in just minutes and die within a few hours.
• Residual contact: If the ant walks over a surface Dethlac has dried on, it’ll still pick up the poison. Death might take a few hours to a day, depending on how much it absorbs.

The best part? The lacquer dries to a hard, invisible finish, so ants won’t know what hit them.

Why It Lasts So Long

Unlike regular sprays that wear off, Dethlac forms a tough, waterproof coating. It sticks to non-porous surfaces like skirting boards, window frames, and tiles, and keeps killing ants for months. Rain or cleaning won’t wash it away. That’s why many users only need to spray once at the start of ant season and enjoy a bug-free summer.

Just One Application = Months of Protection

• Invisible but deadly: No stains, no smell, no yellowing. Just a clear film ants can’t escape.
• No damage: Safe for use on most hard surfaces around the home, just not UPVC or porous surfaces.
• Quick dry: It dries in 10–15 minutes and is safe to touch once dry.

It’s Not Just for Ants

Dethlac also takes down other crawling pests like cockroaches, woodlice, and beetles. It’s a true all-rounder for pest control inside and outside your home.
