Humane Rodent Control Solutions

Controlling and deterring rodents requires a commitment if you want to see long-term effects. When managing rodents, poisons are never a good solution because of their potential secondary effects on children, pets and wildlife.

As well, poisons pose a hazard to our watersheds and environment. Furthermore, the use of poison bait is another attractant for rodents. Poison is not the answer!

The key to reducing rodent populations long-term requires Integrated Pest Management (IPM) utilizing deterrents, exclusion methods and eliminating rodent attraction sources.

Below are Wild Care’s recommendations for reducing or controlling rodent populations humanely and long-term.

Integrated Pest Management:

  • Eliminate food sources that attract rodents. This includes outdoor pet food, cleaning up fruit and berries dropped by trees/shrubs, eliminate waste under bird feeding stations and/or take in bird feeding stations at night. Clean up dog feces promptly. Dog poop is an attractant.
  • Practice good refuse management. Keep garbage receptacles and dumpsters closed at all times. Purchase rodent proof garbage bins and dumpsters.
  • Utilize rodent proof compost bins. Do not throw food waste into your backyard.
  • Trim or remove foliage so they are at least 2 feet away from the side of your home or dwelling, to prevent rodents from climbing, nesting and hiding in them.
  • Seal up cracks, crevices and potential entry points into your home. Use 1/3 inch metal mesh (hardware cloth), not chicken wire, to block entry points.
  • Remove brush piles from near your home or dwelling.
  • Seal up cracks, crevices and potential entry points in your home – with course grade steel wool (#3 or #4). Stuff wool in crevices tightly, then seal with spray foam insulation.
  • *Utilize electronic zappers or snap traps within your homes to control mice. (Never place these outside.)
  • *Humane traps can be used to capture mice and rats in your home. Release rodents outside on your property. Use exclusion techniques to prevent re-entry. MA state regulations require that all wildlife is released back onto your property. It is illegal to relocate wildlife to a new location and often lethal for the animal.
  • Utilize rodent birth control methods below.

* Please note, when using snap traps, electrocution traps or humane trap-and-relocation on your property during the spring and summer months, you are potentially killing/releasing a nursing mother, and leaving babies behind. I recommend utilizing these methods during the fall and winter months to avoid creating orphans. Practice indoor exclusion during spring/summer to prevent rodents from getting in.

Devices and Products for Lethally Controlling Mice and Rats:

  • Rats: Stuff dry ice pellets into burrow entrances/exists. Cover with soil to asphyxiate rats. (Please note, Bell Laboratory produces pellets approved for rodent control. “Rat Ice” is only available for rodent use in certain states.)
  • Rats and Mice: Put instant mashed potato flaxes into re-labeled empty bait boxes. Mix with sunflower seed/peanut butter. (*Remember: Any time you put out a food source, you are attracting rodents.)
  • RatX Product: Kills rats by dehydration
  • A24 Good Nature Autotraps: Self-setting, self-baiting and self-clearing. For rats or mice.
  • Smart Boxes by Anticimex
