The secret is indoxacarb, a powerful insecticide that roaches ingest and carry back to their hiding spots, spreading it through the colony. Unlike sprays that only kill on contact, Advion continues working long after application, often wiping out entire infestations in days.
At around $30–$40 for a four-tube pack, it’s a solid investment for DIY pest control. Thanks to its easy application, long-lasting formula, and low toxicity to pets and kids, it’s ideal for homeowners who want a pro-level solution without calling an exterminator. In this review, we’ll break down how Advion works, how to use it effectively, and when it might be time to call in backup.
Key Takeaways
- The proprietary gel-bait formula uses the powerful insecticide indoxacarb, which only works when it is eaten by certain insects.
- There is no doubt that indoxacarb is a powerful cockroach killer, showing 100% efficacy in some studies.
- Advion Cockroach Gel bait will last up to a month unless the entire dab is eaten by cockroaches.
What Is Advion Cockroach Gel?
Advion Cockroach Gel is a professional-grade roach bait that uses indoxacarb, a slow-acting but highly effective insecticide. The gel works when cockroaches eat it, and because roaches groom, feed on each other’s waste, and cannibalize dead roaches, the poison spreads through the colony naturally.
What sets Advion apart from other gel baits is its sticky, moisture-retaining formula, which makes it easy to apply in tight spots — under appliances, behind toilets, inside cabinets — and stay effective for weeks without drying out or sliding off surfaces.
Roaches are also known to eat each other, each other’s feces, and each other’s vomit. The indoxacarb can easily spread further this way and kill the entire infestation quickly.
Unlike other gel-based roach baits, Advion Evolution Cockroach Gel has a special formula that keeps it both moist and sticky. This allows you to apply the gel in hard-to-reach areas and be sure that the bait will remain available and in place for up to a month.
This is best seen by the vertical surface test, in which Advion products were proven to remain in place on a smooth vertical surface while other gel baits quickly slid down the surface. The easy applicator means you can place roach bait on almost any surface in your home without worrying the bait will move or be lost.
Does Advion Cockroach Gel Work?
Advion works. It’s one of the most effective roach baits on the market, especially for serious infestations. It doesn’t just kill individual roaches; it wipes out colonies.
In head-to-head studies, including one by Purdue University, Advion maintained 100% control, even when other food sources were present. A Texas A&M study showed it outperformed MaxForce bait, needing less product to kill more roaches. That’s due to its high palatability and non-repellent design—roaches don’t avoid it like they do with sprays.
How To Use Advion Cockroach Gel
The application is simple and doesn’t require professional tools. Each box comes with four tubes, a plunger, and a precision nozzle. Here’s how to apply it:
- Target the right areas: Focus on places where roaches hide: behind appliances, around plumbing, under sinks, and inside cabinets.
- Apply small dabs: Use pea-sized drops (less than ⅛” wide, about 2” long). For moderate infestations, apply 1–3 spots per 10 linear feet. For heavier ones, up to 5 spots per 10 feet.
- Avoid contaminating the bait: Don’t spray pesticides near your gel placements; it can make the bait less attractive or ineffective.
- Keep it away from food: Never apply on food prep surfaces or where pets eat. If you do, wipe it away with soap and water.
Pro Tip: If you’re dealing with roaches in food storage areas, use bait stations to keep the gel isolated but accessible to roaches.
How Long Does It Last?
Advion gel typically stays effective for up to 30 days unless it’s eaten sooner. After applying, check the spots every 12–24 hours:
- If the bait is gone, reapply — it means roaches are feeding and you’re making progress.
- If the bait is untouched, leave it for a few more days or relocate it closer to known roach traffic.
Each tube includes a reusable storage cap, so you can save unused gel for later, just store it in a cool, dry place.
If the cockroaches have infested an area very close to food stores, you may want to consider buying bait stations. This is an effective way to give the cockroaches access to the gel bait without putting the bait directly on foodstuffs or allowing it to contact anything that will be eaten by humans or pets.
Finally, don’t spray any pesticides or aerosol sprays near your bait. It could easily contaminate it and make it unattractive to cockroaches, so they won’t eat it.
Should You Reapply?
One round of Advion may be enough for light to moderate infestations. But in high-infestation areas or apartment complexes, you may have to reapply every few weeks. In extreme cases, rotate with another bait like Optigard Cockroach Gel, which contains a different active ingredient (emamectin benzoate) to prevent resistance.
Rotating baits every 90 days aligns with the typical cockroach lifecycle and helps ensure long-term control.
How Fast Does It Work?
Advion doesn’t kill instantly, but that’s by design. Once a roach eats the gel, indoxacarb kicks in within 24–48 hours, allowing time for the insect to return to the colony and spread the poison.
In some cases, it can take up to two weeks to fully collapse a large infestation, depending on colony size and placement accuracy. But unlike contact sprays, Advion keeps working even after the initial treatment, thanks to its secondary and tertiary kill effects.
If a bait has been eaten, simply apply another dab – this means the cockroaches are taking the bait from this spot and you should continue feeding them until they are eradicated. If the bait is not being eaten, you can leave the application for up to a month or until you see more cockroaches.
Do You Need a Bait Gun?
No, you don’t need a bait gun. The tubes include a plunger that works fine for most household use. That said if you’re treating large areas or using multiple tubes, a bait gun can speed up application and improve accuracy. They’re especially helpful for reaching tight crevices or applying consistent-sized dabs.
What Other Pests Will Advion Cockroach Gel Control?
Advion is specifically formulated for cockroaches, including German, American, Oriental, and Brown-banded species. Due to its starch content, some ants may also take the bait, but it’s not ideal for ant control.
If you’re targeting ants, use a product designed for them — you’ll get faster, more effective results.
Is It Safe Around Kids and Pets?
When used properly, Advion is considered very safe. Indoxacarb has low toxicity to mammals, and the gel is designed to be applied in out-of-reach cracks and crevices. It’s not a spray or powder, so there’s very little risk of airborne exposure.
That said, always keep the tubes out of reach, and never apply the gel on surfaces where food is prepared or served. If a child or pet accidentally ingests the gel, call poison control as a precaution, but serious reactions are extremely rare due to the low concentration of the active ingredient.

Advion Evolution Cockroach Gel Bait Vs. Advion Cockroach Gel Bait
Advion offers two versions of its roach gel bait: Advion Cockroach Gel Bait and Advion Evolution. Both contain the same amount of indoxacarb — 0.6% — and kill roaches using the same ingestion-and-transfer method.
The main difference is that the Evolution formula is slightly updated. It’s more attractive to roaches and better at staying in place, especially on vertical or uneven surfaces. It also holds its moisture longer, which can improve performance in high-traffic or hard-to-reach areas.
Evolution typically costs about one dollar more per tube, or four dollars more per box.
If you’re facing a heavy infestation, the Evolution formula is worth the upgrade. For smaller problems or routine maintenance, the original version still delivers solid results.
Final Thoughts: Does Advion Cockroach Gel Bait Work?
If you’re battling a roach problem, Advion Cockroach Gel is one of the most effective DIY solutions available. It’s easy to apply, safe when used correctly, and proven to wipe out entire infestations — even when other food sources are present.
Whether you choose the original formula or the Evolution version, you’re getting a pro-level product trusted by pest control experts. For severe infestations, pair it with regular monitoring and, if needed, rotate with another bait like Optigard for best results.
