You may not see dead ants immediately after applying Phantom II Aerosol Spray as it is a slow kill so it has time to be taken back to the colony and spread. How long it will take to completely eliminate ants depends on the size of the colony you are treating and how many colonies you are treating. You can reapply every 4 weeks but as long as they are contacting the treated area they will die and transfer it back. You should start to notice a reduction in activity within a few days though.
Phantom II Aerosol Spray can be applied to cracks of drawers only (inside edges and along the runners on the outside). Once dry, you can put clothes back in.
