is there a way to delete local parts?

repeat wait() 
until game.Workspace:FindFirstChild("WinerMessage")~= nil
player = game.Players:GetChildren()
for i,v in pairs(player) do
    local playercharacter = v.Character
        if game.Workspace:FindFirstChild("WinerMessage")~= nil then
			playercharacter.Humanoid.LocalBin:Destroy()
end
end

my code ^ -- it wont delete the local parts. i made a script that gives local parts to all the players. i want the local parts to be destroyed if something called 'WinerMessage' pops up in workspace. so basically if a message pops up in workspace names WinerMessage all the local parts should get destroyed all the local parts from each player. i place my local parts in players humanoid. is there a way to delete them?
