Cockroaches Near the Gas Stove and Chimney: Why They Gather There

If you see cockroaches around the hob, behind the cooktop or near the chimney, you are not imagining a pattern. The cooking area gives them warmth, grease and many small gaps, which is why it is one of the most common hotspots in Indian kitchens.

This guide explains why and how to handle it safely, taking care around gas and electrics.

The short answer

Cockroaches gather near the gas stove and chimney because heat keeps the area warm, cooking grease and food splatter provide food, and the gaps around the hob, wall tiles, gas pipe and chimney duct offer shelter and routes into the wall. To control them, degrease the stove, wall and chimney regularly, seal gaps around the pipe and duct, use gel bait placed safely away from heat and flames, and avoid spraying flammable aerosols near the stove.

Why the stove area is attractive

• Warmth: Residual heat keeps cavities warm.
• Grease and splatter: A rich food source on the hob, wall and chimney filter.
• Gaps: Around the gas pipe, hob cut-out and chimney duct opening.
• Dark voids: Behind the cooktop and inside the cabinet below.
• Moisture: Steam and cleaning water.

Where to check

1. Under and around the hob edges
2. The gas pipe entry and regulator area
3. Behind the stove and the wall tiles
4. The chimney body, filter and duct opening
5. The cabinet under the hob
6. Gaps between countertop and wall

Safety first

• Do not spray aerosols or flammable products near the stove or when the gas is on.
• Turn off the gas and the electric supply before cleaning behind the hob or chimney.
• Keep bait away from direct heat and open flames.
• If you smell gas, do not use any treatment. Follow safety procedure and call the gas provider.

Cleaning routine

• Wipe the hob and surrounding wall daily after cooking.
• Degrease the chimney filter and body as the manufacturer advises.
• Clean under the burners and the drip trays weekly.
• Vacuum behind and beside the stove when possible.

Sealing and treatment

• Seal the gap around the gas pipe and the chimney duct with suitable heat-appropriate material.
• Close wall cracks near the hob.
• Ask a professional to place gel bait in cracks and hinges near, not on, the heat zone.
• Treat the main source elsewhere in the kitchen.

When to call a professional

Because of gas and heat, professional treatment is the safer choice here. A technician can choose bait placement and avoid risk, and treat wall voids that home methods cannot reach.

Frequently asked questions

Why are roaches near the stove at night?

They forage for grease and crumbs when the kitchen is quiet and the surface is still warm.

Is it safe to spray near the stove?

No. Avoid aerosols near gas and flames.

Do I need to clean the chimney?

Yes. Grease buildup feeds roaches, and it is good for chimney performance too.

Can I seal the gap around the gas pipe myself?

Ask a qualified person, especially for gas lines. Do not block ventilation.
