How To Identify Rats
Rats are intelligent robust creatures that carry disease and can be very tricky to eradicate. Here are some signs to look for when trying to identify a rat infestation.
Rats are most active at night so you may hear signs of movement or scratching in walls and ceilings. They often gnaw through into rooms at the wall floor junctions under kitchen units, so check for holes in these areas as well as around pipes coming up through flooring. Rats can squeeze through a hole the size of a fifty pence piece. Rub marks are dark shadows left by the oil on rat fur which can often be found around holes or along routes often used by rats (rat runs).
Rats leave around 40 droppings per day, often in one particular area they feel safe in. These droppings are dark brown in a tapered, spindle shape, between 10 and 20mm long. As Rat incisor teeth continually grow they love to gnaw, evidence of this can frequently be found by way of wiring being chewed through in lofts and riser cupboards. Also foot prints and tail swipes can sometimes be seen in very dusty areas.
When looking for signs of rats outside, in the garden and around buildings, look for burrows. These will have an opening of between 5 and 10cm wide and will usually be found around the roots of trees and bushes, in overgrown areas, or going under decking and sheds or down the side of building walls.
The source of rat infestations is often a faulty drainage system so check around the outside of any manholes for evidence of burrows and rat activity.rds. Also foot prints and tail swipes can sometimes be seen in very dusty areas.
How Fast Can A Rat Infestation Grow?
It is estimated that there is 5 times as many rats as humans on planet earth. Rats have between 3 to 12 litters per year. The average Litter size is 8 infants, though can be as many as 14. The female is pregnant for 3 weeks. The infants will be sexually mature and ready to mate within 10 to 12 weeks. So, a pair of brown rats can have as many as 1500 descendants if all are left to breed uninterrupted, within 1 year.
