How to Get Rid Of Weasels in House? (3 Effective Ways)

How to Get Rid Of Weasels in House

You walk into your garage one morning and notice strange debris and droppings scattered around. Upon closer inspection, the insulation covering the walls looks shredded in some areas. Chewed-up boxes and shredded paper litter the floor. If this sounds familiar, it’s likely that weasels have entered your house and settled in.

To effectively remove weasels from your home, use a combination of strategies.

  • Carefully place live cage traps baited with pungent cheeses, meats, or fermented eggs along high-activity areas.
  • Find and seal any entry points using wire mesh, caulk, sealant, or similar materials.
  • Eliminate exterior food sources by securely containing trash and keeping pet food indoors.
  • Set up deterrents such as gravel perimeters and motion-activated sprinklers along weasel access routes.
  • Use strong ammonia and bitrex repellents near potential entry points or nest sites.

This guide offers practical solutions to identify weasel infestation signs, trap techniques for these sneaky invaders, and pro tips to make your home weasel-proof. You’ll soon eliminate these chaotic carnivores and stop others from entering your home.

Signs of Weasel Infestation

Property Damage

Weasels have sharp teeth and claws that can shred materials like insulation, wood trimming, cardboard boxes, and paper. Be on the lookout for:

  • Shredded insulation covering walls and ceilings: Weasels burrow into it to line their nests, often leaving fluff trails or tunneled holes.
  • Wood trim, baseboards, and frames chewed up: Weasels teeth create jagged edges with parallel tooth marks.
  • Cardboard boxes and paper shredded to bits: Weasels use these materials to build their warm, cozy nests.


Weasel poop, resembling dark rice grains, is often found along walls, in quiet corners, attics, and garages – typical nesting areas.

  • Droppings near electrical wiring often indicate weasels are chewing on the rubber insulation.
  • Weasels intentionally leave droppings as territorial markers.

Strange Noises

Weasels are vocal creatures, using various barks, chirps, and distress screams to communicate. Listen for:

  • High-pitched squeaking of baby kits asking for food.
  • Chattering noises near their den sites.
  • Barks or shrill cries when they feel threatened.
  • Scratching sounds from tunneling in walls and insulation.
  • Loud sounds while searching through cupboards and containers.
  • Noise from items being knocked over or displaced.

If you hear such loud noises, particularly active at night, it likely means weasels have invaded your space.

Musky Scent Marks

Weasels have scent glands for marking territory. You might notice a strong musky smell throughout your house. Check baseboards, corners, attics, and garages for any hidden weasel odors.

  • The aroma is incredibly potent, similar to a skunk’s smell.
  • Weasels often re-mark the same areas repeatedly.


Trapping is an effective method to capture rogue weasels wandering inside your home.

Use humane methods to trap weasels when possible. Be quick yet patient, as it requires strategy and diligence.

Here are effective techniques to trap these carnivorous intruders:

1. Best Bets: Live Cage Traps

Live cage traps allow healthy capture and release of weasels when done properly. Look for these features in an effective live trap:

  • Choose metal mesh or solid wood traps, as weasels can chew through plastic.
  • Ensure the trap is large enough, at least 30x12x12 inches in size.
  • Select traps with an easy-to-use door to securely and humanely capture the weasel.
  • Look for a trap with a bait cup to place smelly bait and lure the weasel.

When the weasel follows the bait into the trap, the door closes, leaving it unharmed.

Pro Tip:

  • Cover the trap with a dark cloth to make it resemble a cave, which weasels find irresistible.
  • Install expanded triggers in the trap to catch multiple weasels before resetting.
  • If placed horizontally, secure the trap firmly to prevent weasels from tipping it over.

2. Lure Them In Choosing Irresistible Bait

Enticing bait makes weasels less cautious and draws them to the trap. Smelly foods that appeal to their carnivorous appetite work best:

  • Use raw chicken, beef liver, bacon, or canned fish.
  • Try rotten meats such as aged ham or scraps.
  • Offer various cheeses like Cheddar or Swiss.
  • Consider live insects, small snakes, or feeder mice.
  • Use muskrat or mink gland lures.
  • Try synthetic fermented egg formulas.

Rotate baits often to find the most tempting one. Place bait in both the pan and the bait cup to enhance the trap’s odor.

3. Strategic Placement

Focus trapping efforts along patrol routes in areas with:

  • Areas with confirmed weasel activity and known entry/exit points.
  • Locations with droppings and signs of territory marking.
  • Places where damaged items suggest nest sites.

Prime locations:

  • Attics
  • Garages and sheds
  • Crawl spaces
  • Corners of rooms
  • Under decks

Pro Tip: Set up several traps simultaneously in different areas to boost your chances of success.

Prevention and Exclusion

Use these comprehensive methods to weasel-proof your home, making it a secure fortress.

Cut Off Food Supplies

Food scraps and trash attract weasels. Prevent this by:

  • Using secure bins with tight lids for trash storage. Adding raccoon-proof lid locks. Choosing sturdy steel cans with clamps.
  • Regularly remove fallen fruit and seeds. Clean up the area after storms or seasonally. Trim branches that drop fruit near your home.
  • Cover compost piles with approved bin designs. Store eggshells and vegetable scraps securely.
  • Feed pets indoors and avoid leaving food outside. Clean grills thoroughly to remove meat and grease residues.

Seal Potential Entry Points

Weasels can squeeze through holes as small as 1 inch wide. Seal off any breaches including:

  • Seal cracks and holes in foundations, walls, and roofs. Focus on areas around utility lines. Use metal sleeves, caulk, or spray foam for sealing.
  • Close gaps where wires or pipes enter the building. Weasels can fit through tiny openings; seal them well. Use caulk, cement, foam, flashing, or mesh for sealing.
  • Secure openings near outdoor vents and fans. Vents can be entry points; cover them with 1⁄4” mesh. Fix loose windows and doors for a tight seal.
  • Use weatherstripping to ensure doors and windows close snugly. Check pet doors for possible entry points. Repair loose siding, flashing, or shingles.
  • Apply caulk or silicone to any gaps or cracks. Block holes near ground-level vents with mesh or concrete. Regularly check for new vulnerabilities to outsmart weasels.

Install Physical Deterrents

Use tactile deterrents to keep weasels from climbing or digging in key areas:

  • Place sharp gravel, large rocks, or concrete pads around foundation walls.
  • Install metal sheeting around the building’s perimeter.
  • Use wire fencing bent outward underground to prevent digging.

Employ High-Tech Defenses

  • Set up motion-activated sprinklers to deter weasels along their travel routes.
  • Use ultrasonic repellers to emit high-frequency sounds that weasels find unpleasant.
  • Install solar-powered ultrasonic spikes that send vibrations through the ground.


Natural ingredients and commercial products can irritate weasels’ senses, making them leave your home for good.

Employ Natural Smelly Scents

Weasels have a keen sense of smell, so take advantage by using pungent natural scents as odor repellents:

Ammonia-soaked rags:

  • Sharp ammonia smell deters weasels.
  • Place soaked rags at entry points or nest areas.
  • Soak cotton balls in ammonia or cleaning liquids.


  • Their strong odor repels weasels.
  • Scatter them around foundations, attics, and crawl spaces.

Apple cider vinegar:

  • Mix with water and spray to protect certain areas.
  • Spray around doors, windows, and perimeter walls.

Garlic oil spray:

  • Spray around entrances and reapply after rain.
  • Mix garlic oil, water, and dish soap in a spray bottle.

Predator urine:

  • Use fox or coyote urine from garden stores around your home.
  • Soak cotton balls in urine for den areas.

Change scents often to prevent weasels from getting used to them. Keep pets and children away from ammonia. Reapply repellents after rain or snow.

Deploy Commercial Repellent Sprays

Hardware stores offer commercial-grade repellent sprays designed to irritate weasels’ senses:

Bitrex®-based formulas:

  • These have a very bitter taste that lasts for hours.
  • They strongly affect the weasels’ taste buds.

Hot pepper wax products:

  • These irritate the weasels’ mouths and noses.
  • Made with capsaicin from hot peppers.

Initially, reapply repellents daily, then switch to weekly once weasels stop trying to overcome the irritating effects.

Pro Tip: Combine natural and commercial repellents for the best results.

Professional Help for Trapping and Removal

You’ve tried every DIY method to evict weasels but with limited success. They keep raiding your trash and causing damage, regardless of your efforts.

If weasels continue to be a problem despite your efforts, consider hiring professional trappers. They have the necessary equipment, expertise, and experience to capture weasels in hard-to-reach places.

For the toughest infestations, let experts take over. Their advanced equipment and strategies are effective against even the most challenging weasel problems.

Understanding Weasel Behavior

Knowing why weasels entered your home can help identify the vulnerabilities they exploited. This knowledge is crucial to remove what might attract them again.

A Carnivorous Appetite for More

Weasels, driven by hunger, eat up to a third of their body weight each day. They are always searching for their next meal.

You’ll entice them by:

  • Not managing food waste properly.
  • Leaving pet food accessible.
  • Having rodents or birds around your home.

Remove the temptation by:

  • Remove outdoor food sources.
  • Secure your trash and compost bins.
  • Install a rodent-proof barrier around your foundation.

Habitat Preferences

Weasels look for quiet, warm, and secluded shelters to sleep and raise their young, especially where nest-building materials are available.

You’ll lure them by providing irresistible den locations:

  • Insulated attics make attractive dens.
  • Cluttered garages and sheds.
  • Woodpiles close to the house.
  • Brush piles near foundations.
  • Openings that allow easy access.

Evoke eviction notices by:

  • Seal all indoor entry points.
  • Keep areas clutter-free.
  • Store firewood and lumber away from the house.
  • Clear away debris piles outside.

Breeding and Dispersal Instincts

Once they reach adult size, juveniles leave the nest to establish new territories.

You’ll recruit new settlers by having:

  • Providing a habitat with abundant food and shelter.
  • Having water sources close by.
  • Allowing easy access to cozy den sites.

Proactively eliminating these necessities will deter weasels from settling near your home.
