Advion Hot New Syngenta has Indoxacarb as the active ingredient, which, when ingested, will wipe out the whole roach colony in and around your home. Clear any food remains and debris lying around the house.
After the roach eats the Indoxacarb, it is allowed some moment to travel to its nest. And as mentioned earlier, the roach will regurgitate the food and die in the roach nest.
The other roaches will definitely eat the vomit, feces, and the body of the dead roach, which will poison them to their death. Therefore, the Indoxacarb will cause a horizontal/ secondary kill effect on other roaches in the colony.
Precautions: Avoid using this Advion Hot New Syngenta combined with other contact roach killers like sprays or the ones that kill the cockroach instantly. This is because Indoxacarb is supposed to function effectively when it causes systemic and progressive deaths of roaches, even in their nests.
