How to get rid of rats in an apartment's sewage? - briefly
Seal all cracks and pipe penetrations, then set snap traps or electronic bait stations at sewer access points, and enlist professional pest control if the problem persists. Keep the drainage system clean and ensure continuous water flow to deter re‑entry.
How to get rid of rats in an apartment's sewage? - in detail
Rats can infiltrate the plumbing of a flat, causing damage and health risks. Effective removal requires a systematic approach that combines inspection, exclusion, trapping, and sanitation.
First, locate entry points. Examine pipe joints, vent stacks, and wall penetrations for gaps, cracks, or loose fittings. Use a flashlight to trace the sewer line from the floor drain upward, noting any visible burrows or droppings. Seal openings with steel wool, copper mesh, or expanding foam designed for pest control. Apply caulk or mortar around pipe sleeves and around the base of the drain to eliminate residual gaps.
Second, set traps within the drainage network. Place snap traps or electronic kill devices in accessible sections of the pipe, such as the cleanout cover or a removable grate. Bait with high‑protein foods—peanut butter, dried fruit, or canned meat. Check traps daily, remove carcasses promptly, and reset with fresh bait.
Third, consider rodenticides only when other methods fail. Use bait stations that meet local regulations, positioning them in sealed compartments near the sewer entrance. Rotate active ingredients to prevent resistance, and monitor for non‑target exposure.
Fourth, improve sanitation to deter re‑infestation. Remove food residues from sinks, avoid dumping organic waste into drains, and run hot water regularly to flush the system. Install screens on floor drains and laundry tub outlets to block rodents from entering.
Fifth, enlist professional pest‑control services if the infestation persists. Experts can perform sewer line inspections with cameras, apply foam or concrete sealing, and administer licensed treatments safely.
Maintain the exclusion measures: inspect seals quarterly, replace worn caulk, and keep the drainage area clean. Consistent monitoring and prompt repair of new gaps will prevent rats from re‑establishing a foothold in the apartment’s sewage system.
