Advion Cockroach Gel is a professional-level bait by Syngenta. It contains a slow-acting poison, so the roach normally returns to its nest before dying after consuming the gel. This allows the poison to spread to other cockroaches living in that area.
Advion Cockroach Gel is for both indoor and outdoor use, but consumers should never place it in areas that are easily accessible to children or pets. To use, apply a small dot of gel to areas where roaches have been seen, and repeat as often as necessary. However, customers should keep in mind that it can take several weeks to see results if the infestation is severe.
