My cat ate a dead roach with Indoxacarb. Is there a toxicity risk?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 1 year and 2 months old | 12 lbs

Hi there, I am researching pest control products and came across Indoxacarb which is used in Activyl for flea control. I am looking to purchase Advion cockroach bait which also uses Indoxacarb as the active. I know that Indoxacarb remains active in dead cockroaches so that others will die after eating them. Is there a risk of Indoxacarb toxicity if my cats ingest dead cockroaches with the chemical inside of them?

If ingested in high doses, indoxacarb can lead to seizures in cats. However, this medication has a relatively high margin of safety in both dogs and cats. I do not know how many indoxacarb-containing cockroaches would constitute a toxic dose., but it is unlikely that eating an infected cockroach or two will cause significant problems. Obviously try to avoid ingestion of any cockroaches if at all possible. Ideally consider kenneling Fox or sending him to a friend's house while you are treating your home for cockroaches to avoid exposure.
