Advion Cockroach Gel Bait, 4 Tubes x 30-Grams, 4 Plunger and 4 Tips, German Roach Insect Pest Control, Indoor and Outdoor Use, Roach Killer Gel for American, German and Other Major Cockroach Species

Why I reached for Advion gel

A sudden uptick of German roaches in a rental kitchen pushed me to try Advion gel. I’d already done the usual: deep clean, seal food, take out the trash nightly, and lay out a few generic baits. The activity slowed but never stopped. I wanted a professional-grade bait I could place precisely where roaches live—not just where I could reach with a spray. Advion’s non-repellent formulation and indoxacarb active ingredient fit the bill, and the kit’s four syringes with plungers and fine tips promised a cleaner, more targeted approach.

Setup and application

Straight out of the box, the system is tidy: four 30-gram tubes, each with a plunger and narrow tips that make placement simple. The gel is brown and slightly tacky—easy to deposit as small dots or short lines without smearing.

My prep looked like this:
- Vacuum and wipe down surfaces (especially grease along stove sides and under appliances).
- Remove competing food sources: crumbs, pet food overnight, and standing water where possible.
- Identify harborages: cabinet hinges, under the fridge motor area, along backsplash cracks, inside drawer runners, behind the oven, and along plumbing penetrations under the sink.

I placed pea-sized dots every 8–12 inches in those concealed areas, focusing on tight cracks and dark corners. A little goes a long way; heavy blobs just dry faster and can be wasted. The included tips let me tuck bait into narrow seams without making a mess, which matters if you’re placing many small applications instead of a few big ones.

One tip: avoid placing bait where you’ll wipe daily. Also avoid treating right next to freshly sprayed insecticide; repellent residues can keep roaches from feeding on the gel. If you’ve recently used a strong spray, clean or wait before you bait.

What happened after placement

The first 24–48 hours brought a noticeable change. I saw more roaches in the open at odd times, many moving slowly—classic signs they’ve fed and are succumbing. Over the next week, activity dropped sharply. By the two-week mark, I was down to the occasional straggler.

Indoxacarb is non-repellent and works through ingestion, which is exactly what you want in a bait. The gel also benefits from secondary transfer: roaches that feed on it can contaminate others through feces or shared harborages. In practice, that means you don’t have to hit every nest to see colony-level reductions.

As with any gel, drying is inevitable. In warm kitchens and near appliances, the bait can firm up within a day or two. That doesn’t make it useless—roaches can still nibble at dried deposits—but I found that light touch-ups after 2–3 days in high-traffic spots kept the feeding going. In cooler, shaded cracks, placements stayed pliable longer.

How the formulation factors in

At 0.6% indoxacarb, Advion gel has a strong track record in structural pest control. It’s non-repellent, has good palatability (roaches readily feed), and the bait matrix strikes a good balance between staying put and remaining attractive. I also appreciate the targeted nature of the active ingredient. Used correctly and placed out of reach, it’s designed to limit impacts on non-target organisms while remaining potent against roaches.

For indoor work, the lack of strong odor and the precise tips are big wins. Outdoors, you can use it in sheltered spots (meter boxes, under siding lips, in cracks of masonry, and around trash areas), but protect it from rain and direct sun—weathering will shorten its usable life.

Where Advion gel shines

• High attraction under real-world conditions: Even in kitchens with food competition, the dots drew steady feeding.
• Precision placement: The syringes and tips allow clean applications in tight seams and around hardware where roaches travel.
• Speed and depth of control: Expect noticeable reductions in days and substantial control within two weeks if you prep properly.
• Good value for ongoing maintenance: Four 30-gram tubes cover a lot of ground. I used under a single tube to handle a moderate kitchen infestation and had plenty left for follow-up.

Where it falls short

• Dry-out requires touch-ups: Especially near heat sources. Expect to revisit placements after the first couple of days and again at the one-week mark if activity persists.
• Not a silver bullet without sanitation: If food and water are abundant, bait consumption drops and results slow.
• Resistance management is on you: In sites with chronic pressure or long-term use of a single bait, performance may dip over time. Rotating active ingredients or bait types is smart IPM.
• Outdoor exposure limits: Unprotected placements won’t hold up to rain or direct sun, so you need to be strategic.

Practical tips for best results

• Start with cleanliness: Degrease stove sides, clean under appliances, and keep sinks dry overnight if possible. Starving the population boosts bait uptake.
• Place small, frequent dots: Think pea-sized placements every 8–12 inches along routes and in harborage. Thin lines can work behind appliances and along cracks.
• Refresh, don’t heap: If a dot disappears or is ringed with fecal spotting, that’s a feeding site—refresh with a small new dot rather than piling on a blob.
• Avoid contamination: Don’t spray repellent insecticides near your bait. If you need knockdown, use non-repellent residuals compatible with baiting strategies, or keep sprays away from baited zones.
• Monitor weekly for a month: Lightly reapply in hotspots. Once activity collapses, switch to preventive placements in a few strategic locations.
• Store correctly: Unused tubes keep well when sealed and stored cool and dry. The product lists a multi-year shelf life; I’ve had no issues using a tube months later.
• Follow the label: Keep bait out of reach of kids and pets, and use only for labeled pests. This is not a rodent product—don’t improvise.

Value and scope

Each package contains four 30-gram tubes, which is generous. For a typical apartment kitchen plus a bathroom, one tube is often enough to knock down activity and handle touch-ups. Larger homes or multi-unit buildings benefit from the extra capacity, especially if you’re also treating utility closets, laundry areas, and sheltered outdoor harborages.

Because the gel is non-staining and low-odor, it’s suitable for sensitive areas like around appliances, inside cabinet hinges, and behind baseboards—places where you wouldn’t spray. That flexibility is a big part of its value.

Consider rotation and integrated control

If you manage a long-term or building-wide problem, plan for rotation. Alternate with baits using different actives or bait matrices to avoid selection pressure and bait fatigue. Pair the gel with physical measures: sealing wall penetrations, fixing leaks, installing door sweeps, and establishing a strict cleaning routine, especially at night. Traps (monitoring glue boards) help you track progress without interfering with baiting.

Bottom line

Advion gel earns its reputation through consistent, practical performance. It places easily, attracts feeding even in cluttered environments, and provides both quick relief and sustained control when paired with good sanitation. The drying characteristic means you’ll do light touch-ups, and long-term sites should plan for bait rotation. But if you prep correctly and use small, well-placed dots, the results are fast and thorough.

Recommendation: I recommend Advion gel for homeowners, renters, and facility managers who want a professional-grade cockroach bait that’s easy to deploy and effective against German, American, and related species. It stands out for its non-repellent formulation, strong palatability, and precise application hardware. Use it within a broader IPM plan—cleaning, exclusion, and smart monitoring—and it delivers reliable control without the mess or odor of broad sprays.
