Can you put cockroach bait in air vents?

• <div><p>We don’t recommend putting cockroach bait traps inside your air vents. While it may seem like a simple way to trap roaches where they hide, the bait traps can contain chemicals that aren’t great for humans or pets to inhale. Instead, implement the removal methods of fixing air conditioner leaks, sealing any cracks, and hiring an HVAC professional. </p></div>

Q: Is it mold or dust in my air vent?

• <div><p>You normally won&rsquo;t see any dust or mold actively floating out of your vent, but you might notice your vent looks dirty. Mold will cling to the sides and collect almost like black soot. Dust will look, well, dusty, but there will usually be a heavy buildup so expect thick gray layers on the bottom and sometimes the sides of the vent. <b>If you suspect you have mold in your vents, call a professional immediately. </b></p></div>

"Great! Very impressed with the professionalism of this company. Men wore booties in the house to keep from tracking in dirt. I’m picky about that! My husband had watched a YouTube video recently on the proper way to have duct work cleaned. It just so happened, the men also followed the same procedure. They were courteous and answered all the questions we had."
