How Much Does Roach Extermination Cost? (2026 Guide)
One-time vs. quarterly, gel bait vs. spray — a breakdown of what pros charge and what you actually get.
Roach treatment costs vary widely by home size, species, and how bad the infestation is. Here's what to expect.
Typical price ranges
- One-time treatment (small apartment): $100–$200
- One-time treatment (single-family home): $200–$400
- Heavy infestation with follow-up visits: $400–$700
- Quarterly maintenance plan: $40–$70 per visit
Why gel bait beats spray
Off-the-shelf sprays kill the roaches you see but scatter the colony. Professional gel baits are carried back to nests by foragers, killing the queen and next generation. That is why one gel-bait treatment often outperforms months of DIY spray.
