Roach bait gel / cockroach spray — household safety profile

Elevated risk

Indoor cockroach control products in gel bait (syringe applicator) or aerosol spray formats.

What is this product?

Indoor cockroach control products in gel bait (syringe applicator) or aerosol spray formats. Gel baits typically contain fipronil or hydramethylnon as the active ingredient in a food-grade attractant matrix. Spray formats use fast-knockdown pyrethroids. Primary hazard is accidental ingestion by children and pets who contact bait placements. Fipronil disrupts GABA-gated chloride channels; hydramethylnon inhibits mitochondrial electron transport. Boric acid formulations offer lower acute toxicity but chronic exposure risk.
