This is how to prevent spiders, scorpions and other insects from crawling through HVAC vents. HVAC registers are a common point-of-entry for insects, especially if there is a basement below. Most HVAC duct work has small holes and insects can enter the HVAC duct work through through the small holes and then enter the house. These HVAC register covers still allow air to flow but deter most insects, snakes, lizards, etc. from being able to crawl through the HVAC register. If you have an insect problem in your house, these magnetic HVAC vent covers may help with the problem. These magnetic HVAC vent covers may also better prevent jewelry, trash and other items from falling into the HVAC duct work. #Howto #Insects #Spiders #Scorpions
