I have put 2 small stones in the canister but find that I have to shake it often or it stops putting out dust. Have it 1/2-3/4 full. It is scary to be in or beside a hornet nest and have no dust coming out!
We would recommend that you do not fill it any more than half full. Unfortunately, putting a stone and/or penny in the bulb will help keep the dust from clumping too fast but you will still need to shake the duster occasionally.
