It would involve constant vigilance and good habits which are geared to cleanliness, structural integrity, and awareness. First, regular checks in your home would be in order; inspect any new signs of rodent activities especially around food storage areas such as the kitchen or pantry, or in otherwise secluded spaces like the basement or attic. Clean your living space very well: pick up crumbs and spills instantly, clean food and not keep pets' food overnight. Attractants may be reduced by a consistent practice related to waste management whereby waste should be sealed in good containers and put into the trash often. It is also advisable to keep the outdoor places clean; cut shrubs and trees, clear the chaff and debris, and pile firewood far away from the house as rodents may hide in these areas. Use natural repellents around the entry points and suspected nesting sites using essential oils. Door sweeps can be installed, and windows need to be sealed to eliminate any possible entry routes. Educate your family members about these practices; involve all family members in the maintenance of a clean home, and report any signs of rodent activity immediately. Lastly, you may want to arrange for periodic inspections by pest control professionals who can offer expert advice and assistance in identifying vulnerabilities in your home. Adhering to these tips devoutly will give you an easy, rat-repelling place to live and hence avoid rat infestation.
