Guard your castle: The power of Six Feet Under: Barricade

Six Feet Under: Barricade

Spring welcomes warmth, longer days and the beginnings of gardens—but they also awaken the pests. Ants marching, beetles burrowing and cockroaches seeking shelter can turn your home into their next conquest unless you fight back. Dr. Killigan's Six Feet Under: Barricade Household Insect Kit is here to defend your kingdom.

This is no ordinary insect treatment. Barricade is an advanced, plant-based perimeter defense, crafted for those wanting an eco-conscious solution to pest control. With the power of soybean oil, plant-based sodium lauryl sulfate and peppermint oil, this formula creates a barrier around your home’s exterior, stopping pests dead in their tracks.

Unlike traditional pesticides, Barricade doesn’t rely on chemical poisons. It works through a mechanical-kill method, physically disrupting pests upon contact. This means pests cannot adapt, mutate or build resistance over time.

Six Feet Under: Barricade

We’ve formulated Barricade using only ingredients recognized as "minimum risk" under the U.S. Environmental Protection Agency (EPA). These plant-based components are the safest in pest control—harmless to you, your family and your pets when used as directed. Yet, they remain lethal to the insects you want gone.

The application is simple and effective. In just mere minutes, you can apply Barricade around the perimeter of your home, fortifying your walls and doorways with a protective shield. One treatment offers up to 90 days of uninterrupted protection, keeping ants, roaches, beetles and other intruders where they belong—out.

With Barricade, you’re investing in your peace of mind, your safety and your home’s integrity—all without the expense of an exterminator.

It’s no wonder The Daily Beast and Newsweek have hailed it as “a breakthrough in planet- and wallet-friendly outdoor pest control.” With Barricade, the balance of power shifts—away from harsh chemicals and toward a smarter, safer future.

Dr. Killigan’s Barricade is not just plant-powered. It’s your new secret weapon.

Six Feet Under: Barricade Household Insect Kit • Mechanical-kill method – prevents resistance • Plant-based, EPA-exempt ingredients • Lasts up to 90 days • Safe when used as directed for people, pets and the planet

Defend your home the Dr. Killigan's way.
