What are they doing?
They get into poultry houses and kill the birds
Killing pet rabbits or hamsters
Legal status in Arkansas:
Protected. Weasels are a protected furbearing species that may be taken during the set trapping season.
Weasels may not be hunted
Exclude them from poultry houses:
Close off any holes that are 1” or greater. Use ½” mesh cloth. Or wire mesh to cover the holes
Secure the doors at night
Bury the fence 6 inches into the ground to prevent the weasel from squeezing under it
Use wire mesh fencing that weasels cannot squeeze through the holes
Startle the weasel:
Set up a motion activated sprinkler. Set it up where the weasel is gaining access to the vulnerable area such as a hole in the fence or entryway into a barn
Do not stack wood against the barn or house
Remove low hanging branches on brush and shrubs
Keep the weeds and grass around poultry houses and rabbit pens well trimmed
Remove rock and brush piles from the yard
Remove artificial food sources:
Properly dispose of livestock carcasses
Secure garbage with tight fitting lid
Keep Weasels from Denning in barns:
Close doors when not using
Put wire mesh over holes to prevent entry
Weasels are curious animals and can be trapped relatively easily
If a weasel is in your house using a small cage trap is best
Set the trap near the wall or areas of cover
Bait the trap with fresh meat
Rat traps, only use larger snap traps as mouse traps will not kill weasels
Preferred killing methods:
Shooting, using a shotgun or a .22 caliber rifle
Acceptable killing methods:
Stunning and chest compression
Control strategies that don’t work particularly well or aren’t legal in Arkansas:
Collect dog or cat hair and spread it around the area weasels frequent
Sprinkle red pepper flakes around the perimeter of the area you are trying to keep the weasels out of. The flakes will irritate any soft tissue it comes into contact with
Noisemakers may startle the weasel but won’t drive them off
