Drain Cleaning and Pest Control in Commercial Kitchens

Kitchen drains collect grease and food residue, which feed flies and cockroaches and can hide rodents' entry routes.

Regular drain care is a key part of pest prevention.

The short answer

Clean drains and grease traps regularly, scrub the inside of floor drains, keep covers in place, fix leaks and ensure proper flow. Dirty drains produce drain flies and fruit flies and shelter cockroaches. Combine cleaning with professional pest control.

Problems drains cause

• Drain flies and fruit flies.
• Cockroaches nesting in pipes and gaps.
• Odours and slippery floors.
• Possible rodent access if pipes are damaged.

Maintenance routine

1. Daily: flush with hot water and clean strainers.
2. Weekly: scrub floor drains and covers.
3. Regularly: service grease traps.
4. As needed: repair broken pipes and seals.

Pest checks

• Look for flies around drains.
• Check for cockroaches at night.
• Inspect covers and seals.

When to call help

If flies or cockroaches keep returning despite cleaning, ask the provider and a plumber to inspect for hidden leaks or damaged pipes.

When to call a professional

If the problem is widespread, keeps returning or you are unsure what you are dealing with, a professional inspection will save time and avoid wasted effort.
