NH's most serious indoor roach breeds in weeks, defeats foggers, and triggers asthma. Here's the honest control plan — and why DIY usually fails.

Raid Ant & Roach spray is a dual-pyrethroid contact killer. Dogs tolerate it once dry — but keep cats, birds, and fish away. Honest, vet-sourced safety guide.

Combat Max 12-Month Roach Bait uses enclosed fipronil stations — low-risk when intact, but hazardous if chewed open. Honest, vet-sourced pet safety guide.
