Description
Our verdict: One of the most targeted ant treatments you can buy. The syringe puts tiny dots of fipronil gel exactly where the ants are coming from, such as cracks in skirting, window frames and gaps under worktops, and the ants carry it home to the nest. It’s fast for a bait, but fipronil is a strong insecticide, so apply it carefully, out of reach of pets, and keep it out of drains.
Best for: ants coming from cracks and gaps indoors | Size: 27g syringe | Active: fipronil
What is Combat Ant Killing Gel?
Combat Ant Killing Gel is a bait gel in a precision syringe. It contains fipronil, an insecticide that works slowly enough for worker ants to carry it back to the nest and share it with the colony, including the queen and larvae. The gel has a high water content, which ants find attractive, so they feed on it readily.
The manufacturer says it controls ants in as little as 3–5 days, with fipronil starting to work within hours. Because it’s a gel rather than a station, you can put it right into the cracks, gaps and entry points where ants are coming from.
How to use it properly
- Find the entry points. Follow the trail back to the crack, gap or hole the ants are using.
- Apply small dots, about the size of a lentil, in and beside the crack. Several small dots beat one big blob.
- Leave the ants alone. Don’t spray or wipe the trail while they’re feeding.
- Top up any dots that have been eaten after a few days.
- Keep it away from food-preparation surfaces, out of reach of children and pets, and never apply it near drains or watercourses.

Who should pick something else?
- Have pets that might lick it? Enclosed FERRIS bait stations (4-pack) or Nippon Ant Stop stations keep the bait contained.
- Ants at lots of points? Try Barrettine MoBe bait stations (4-pack).

Frequently asked questions
How long does Combat ant gel take to work?
The manufacturer says 3–5 days to control the colony, with fipronil starting to work within hours of the ants feeding.
Where should I apply Combat ant gel?
In and next to the cracks, crevices and entry points the ants use, in small dots. Avoid surfaces where you prepare food.
Is Combat ant gel safe for pets?
Fipronil is a strong insecticide. Apply the gel only in cracks and places pets can’t reach or lick, and consider an enclosed bait station if you have curious pets. See our guide for homes with pets.
Why are there more ants after I applied it?
That’s normal. The gel attracts foragers, and more of them come to feed and carry it back to the nest before numbers drop.
