Rodent Repellent
The most effective rodent repellent method is cleanliness. Most rodents are scavengers and will consume any food available to them. After locating a secure food source, rodents will nest within close proximity and populations grow at rapid rates. It is important to store trash in tightly sealed containers and to dispose of garbage regularly. Coordinated effort with neighbors will help to further prevent rodent infestations.
Repellents may also be used to deter rodent populations. Both natural and chemical-based repellents are commercially available and vary in effectiveness. The smells of some plants, such as eucalyptus, wormwood and mint, are unattractive to rodents. Concentrated application may be effective at repelling rodents for days at a time. Repellent dusts produced by manufacturers work in much the same way.
Sound-based repellents are capable of emitting sound at a register too high for humans to recognize. These sounds are disconcerting for rodents and tend to prevent them from infesting the area around them. However, sound-based repellents also bother house pets.
In the event of an infestation, contact your local pest control expert. Repelling rodents from certain areas within the home may prove effective for a few days, but the effect is localized and does not address entire populations. Professional extermination methods are often required in addition to repellent measures.
