Clean air ducts every five years. Save money doing it yourself. Use a small dog to crawl through the vents with a vacuum cleaner attached to its body. To get the extra dust apply glue to the dog's fur. After the job is complete have dog's fur clipped.
Insects thrive on crumbs.
You can cut down on crumbs and insects by eating out. If your dog sheds fur that mats into your carpet there is a way to get it out. Use his curry comb on the carpet. Prevent it from happening again by having your dog shaved or replacing your carpet with tile. Don't waste time and effort cleaning spiders and webs out of your home.
