    “I bought this to get rid of the ants that built a nest in my flagstone patio and sidewalk. I have granddaughters and pets, and I didn't want to use chemicals that could make them sick if they were exposed. I've used other natural pesticides in the past with mild success but this stuff definitely does the trick! I've only had to spray one time over a month ago...still no sign of the ants returning. 10/10, will be purchasing more.”—S.K., Verified Customer of Dr. Killigan’s

    Say goodbye to bugs without toxic insecticides and costly pest management services

    If you're struggling with a bug infestation, you’re all too familiar with the frustration and cost that come with trying to get rid of it. Not only can six- and eight-legged intruders make you feel uncomfortable in your own home, toxic chemicals and expensive pest management services can do more harm than good, leading to more problems instead of solutions.


    Dr. Killigan’s Six Feet Under Non-Toxic Insect Spray is a plant-based bug killer designed for environmentally conscious individuals aiming to safely protect their households from unwanted pests.

    Safely and effectively eliminate household insects

    Six Feet Under is backed by years of study, testing, more study, revisions and retesting, ensuring this all-in-one solution solves both the problem of insects and the problem of dangerous insecticides. Toxic alternatives not only jeopardize the safety of your home but also contain ingredients that insects can build resistance against.


    Unlike these chemical solutions that aim to affect only specific parts of insects, Six Feet Under targets the entire bodies of bugs, rendering it virtually impossible for them to build resistance against Dr. Killigan’s plant-based formula. Using a blend of soybean, clove and cinnamon oils, Six Feet Under can put an end to your bug problem.

    Count on Six Feet Under for total victory against bugs

    Six Feet Under’s primary killing agent, soybean oil, delivers the death blow to cockroaches, ants, mosquitoes, moths and other six- and eight-legged intruders. This ingredient breaks down the exo-skeleton of the insect, acting as a penetrant and working synergistically with the other essential oils in the formula to enhance their effectiveness and ability to be absorbed into the insect’s system.

    Soybean oil in Six Feet Under also suffocates insects, as they breathe through spiracles and these oils barricade the availability of oxygen. Specific metabolic processes are also crippled by this plant-derived weapon, serving bugs their last meal.

    Clove and cinnamon oils enhance the termination process with compounds of naturally occurring eugenol and cinnemaldehyde (from the clove and cinnamon oils), attacking and shutting down the insect’s nervous system. Modes of action include inhalation, ingestion and absorption, all of which are accelerated with the soybean oil’s rapid penetration of the insect’s exoskeleton.

    Six Feet Under is proven to kill a vast range of insects, including—

      • Ants, including the Argentine ant, black house ant, carpenter ant, fire ant, ghost ant, odorous house ant, pavement ant and pharaoh ant
      • Cockroaches, including the American cockroach, brown banded cockroach, Oriental cockroach and German cockroach
      • Fleas, silverfish, earwigs and firebrats

    Frequently Asked Questions

    Please use common sense. Don’t spray in your mouth, eyes, etc. We value our customers' health and always want to provide a safe and effective product. In general, if you’re spraying something other than an insect, it’s safe to use as directed. This is not designed to be a traditional garden remedy.

    Our Six Feet Under spray is a kill-on-contact solution, meaning it is a rapid, effective bug killer. We recently upgraded our formula to contain a residual component best used on porous surfaces to kill for up to 30 days, which will assist in defending your home from any pesky six-legged intruders even longer. We recommend spraying a fine mist as a barrier around areas that insects are using to get into your home or where there is visible insect traffic- most commonly baseboards, the perimeter of your home, in pantry cracks and crevices, etc.

    The amount of time it takes for an insect to die will depend on the species of insect. Insects such as sugar ants will die almost instantly whereas cockroaches can take up to a minute to die as they have a hard protective exterior. If an insect has a hard exterior or hair on their body it may take longer for Six Feet Under to permeate their body, but rest assured it will still kill them.

    This formula is not designed to kill spiders due to the physiological differences between most insects and spiders.

    Six Feet Under has a two year shelf life when stored as directed in a cool place.

    Yes, although we don’t recommend soaking them. A fine mist will do the trick. Make sure you test fabrics first in an inconspicuous spot before committing.

    Six Feet Under will kill bed bugs, but it is not a long-term solution to bed bug infestations.
