Six Feet Under | Pet-safe indoor insect spray for effective ant control
When ants make their way indoors, you need a solution that stops them quickly—without putting your pets at risk. Six Feet Under is Dr. Killigan's plant-powered insect spray, proven to kill ants [such as Argentine ants, black house ants, carpenter ants, fire ants, ghost ants, odorous house ants, pavement ants and pharaoh ants] along with many other household insects.
This kill-on-contact formula combines clove essential oil, cinnamon essential oil and soybean oil to penetrate ants' exoskeletons and disrupt their systems on contact. With Six Feet Under, you can treat problem areas confidently.
Six Feet Under provides ongoing protection for up to 30 days.
Note: We disclose the percentage of every ingredient because transparency is part of our promise. Six Feet Under contains tiny amounts of clove oil (0.03%) and cinnamon oil (0.03%), which can be toxic to cats in high concentrations. While these levels are extremely low, we recommend extra precaution—allow the spray to fully settle and dry before letting your cat reenter the treated area.

Dust to Dust | Outdoor ant killer that is safe for pets
Your yard should be a haven—not an all-you-can-eat buffet for ants. Dust to Dust is Dr. Killigan’s outdoor ant killer—safe for pets—is a plant-powered formula that stops ants in their tracks.
This fine powder blends rosemary oil, peppermint oil and silica to target ants (including odorous house ants, pavement ants and black carpenter ants) plus a host of other crawling and flying pests. Apply it directly to problem spots or lay down a pest-blocking perimeter around doorways, patios and foundation lines.
Dust to Dust gets to work on contact and keeps protecting as long as it stays dry. A little goes a long way—just a light puff is all you need. Reapply only after heavy rain or if the treated area is disturbed.
Note: Dust to Dust contains rosemary oil (0.5%) and peppermint oil (0.5%). While these plant oils are safe in low concentrations, we recommend allowing treated areas to settle before letting pets roam freely—especially cats, who can be more sensitive to essential oils.

Six Feet Under: Barricade | Long-lasting perimeter defense, safe for pets

Note: Six Feet Under: Barricade contains peppermint oil (5.3%).
