Only after it is cleaned and checked. Pets and young children are closer to floors, so they can be affected more. Keep them out until the crew says the work is complete.
If the heating or cooling system ran, it may have pulled irritant particles into vents and ducts and moved them to other rooms. Crews isolate and clean the system so residue does not spread again.
It depends on the agent, the room and the surfaces. Some residue fades in a few days, while some types cling to fabrics and carpet much longer. If burning returns when you go back in, the residue is still there.
Not reliably. Vinegar and bleach do not neutralize these agents, and mixing products can release harmful fumes. Plain water can spread residue. Fresh air and professional removal work better.
No. Baking soda is not a reliable fix, and it may only move residue around. A cleanup crew uses products matched to the agent and removes contamination instead of masking it.
The cost depends on the size of the area, the type of agent, how much soft furniture and carpet was reached and whether the air system ran. The cleanup team sets its price after seeing the space.
