If there is plenty of food and shelter, Roof Rats will gladly live in close proximity to humans, particularly in attics, ceilings and wall areas. Roof rats enjoy inhabiting upper areas of buildings or homes, often gnawing on wires found there, causing fires, outages and production down-time.
The roof rat is implicated in the transmission of a number of diseases to humans and also to pets. They prefer to forage for food above ground in elevated areas indoors and out. Don’t risk your family’s and pet’s safety with disease and potential damage that these creatures can cause.
Below is information on rat repellent, traps and rodenticides. We also offer some prevention tips that will help keep your rodent population from increasing. Rodent proofing your home is the best natural rat repellent.
Rat traps are an effective method of non-toxic Roof rat control. There are 3 types of rat traps commonly used for rodent control: Snap Traps, Glue Traps, and Electronic Traps.
These mechanical traps provide a quick solution to a rodent control problem and can be used many times. One advantage of rat traps is the ability to “recover” the rat to confirm its elimination.
The most important technique for effective trapping is good trap placement in areas of high rodent activity. The most common trapping mistake is using too few traps.
Statistics show that more rodents are trapped on the first night than on any other night. For this reason, it is essential to use a large number of traps initially.
Some rats are harder to catch and are Neophobic or “extra cautious” of new objects that suddenly appear in their environment. For these cases, rat traps should be placed out but left unset and baited for a couple of days prior to setting the traps.
Rodenticides, also known as rodent baits, offer an economical and efficient approach for eliminating rat populations. Just as with trapping, it is critical to place rodenticides in the correct location – typically against the wall between the nest and the source of food.
Additionally, baits should be placed into areas that appear to be their favorite locations (evidenced by piles of droppings, shredded paper, tracks, etc.). Because rats travel further to feed than mice, baits should be placed between 15 to 50 feet apart.
For best acceptance, place rodent baits out during the late afternoon so they will be fresh at dusk when rats become active.
Ultrasonic rodent repellents are an effective method of controlling rats. These high-pitched frequency sound waves emit a non-repetitive pattern to prevent rodents from habituating to the sound.
For additional effectiveness, the loudest spike in sound replicates the scream of a dominant male mouse. Rodents are very territorial and will constantly fight to establish dominance. The sound of a dominant rodent will discourage others from inhabiting a territory.
It is important to note that ultrasonic frequencies do not travel between walls. So for the most effective rat control, ultrasonic units need to be placed in multiple rooms.
The most common repellent mistake is using them alone to control an established infestation.
