Rodent Control

The City of Chicago provides several options for rodent baiting. If you see rodents in either the alley behind your home, or on your property (front or back yard, gangway, etc.), please call our office at 773-525-6034. We will work with the Bureau of Rodent Control to bait the area to prevent further rodent sightings. 



Note: If you request rodent control bait your property, we will pass your information (name, address, phone number) onto the Bureau of Rodent Control to schedule a baiting appointment. You must be present for the baiting, rodent control needs permission from the owner/tenant of the home to enter the property.  Please note: Rodent Control will NOT inspect or bait the property with out the property owner or a representative on site.

The bait used by Rodent Control is an anticoagulant, which causes rodents to dehydrate internally and seek a water/moisture source. When an area has been baited, there will be an uptick in rodent activity which will last a couple of days, as the rodents seek a water source. 

Rodent Control-These are a few simple proactive things residents can do to be part of the solution:


  • Pickup after your Dog.  Dog excrement is one most common contributors to the City of Chicago's Rodent population.  Dog excrement is is a Rodent favorite!  If you are experiencing issues with dog owners neglecting to clean up after their dog, please contact our office to reserve a parkway sign.  You can preview the sign by clicking on the link below

  • Eliminate food sources; clean up pet waste, don’t overflow garbage carts or put garbage bags on the ground next to the carts.
  • Rid outdoor areas of old lumber, brick piles, junk autos, old equipment or any other debris that potentially shelters rats. If you need to store any of these materials, place them at least 18 inches above ground level and at least one foot away from any wall or fence.
  • Look for holes in pavement or walls.
  • For large openings, it may be necessary to first cover the open area with the hardware cloth and then solidify the opening with fresh concrete or blacktop as needed.Give careful attention to the exterior doors, making sure any opening to the door and floor is too small for rats and mice to enter (less than three-eighths of an inch).
  • Loading docks can become harborage when the steel corner plates are loose enough for rodents to squeeze behind them; the chicken wire and/or hardware cloth method can deny them further entry.
  • Close any such openings by inserting a ball of chicken wire and/or hardware cloth into the holes so tightly it cannot easily be removed; then cement over the opening with fresh concrete mix.
  • Another common rat harborage area is the small easement space between two adjoining buildings that runs between the street & the alley. Often this space is too narrow for a person to walk through, making it more secure for rats to set up housekeeping. Both property owners should work together to anchor a strip of sheet metal connecting the property walls from the ground level to a height of at least seven feet. This metal can be pre-colored, particularly on the street side, to complement the appearance of the buildings.
  • For larger easement openings which often house air conditioners or other exterior equipment, a tightly sealed metal locked door with a concrete threshold at each end will deny rats access to this space.
  • Make sure garbage carts are securely closed. Periodically rinse your garbage storage area and keep the area swept, clean and free of food debris.
  • Pine Scented cleaners deter rodents (Pine Sol or Pin-A-Len are strongly scented). Periodically clean your carts inside and out with a pine scented cleaner.
  • If your carts are in need of replacement due to rodent holes or missing/damaged lids, please call either our office or 311 to request a new cart. Please note, cart delivery may take up to eight weeks.
  • Check garden hose connections, gutters and downspouts and eliminate any water sources. Dripping hoses, containers/planters with standing water, etc. should be repaired or removed.
  • Overgrown weeds, ground cover and dense plants provide the perfect nesting places for rodents. Keep landscape pruned and free of weeds and debris.
  • Always call 311 to report rodent activity and request baiting. The 311 Call Center is the “hub” for all City Services and is a mechanism of tracking used by all City Departments. Any rodent complaints received by our office are also input to the 311 System.  Please note, rodent control will not bait private property unless the owner or an authorized representative is on site.
