Lifecycle, Diet & All

Rodent Characteristic

The Rodent Lifecycle

They need at least 3 weeks to mature from birth to adulthood. In 5 weeks, they are already sexually mature and can start reproducing. On average they can live for about one year, those that lives indoor can live for 2 to 3 years. They can survive longer in a safe environment.

Baby rat weighs about 3 to 6 grams, depending on the species and at birth blind and naked without any fur. After 6 days, they will start opening their eyes. Then at the start of the third week, they will start growing fur.

The Rodent Anatomy

They have upper and lower pair of incisor teeth, used for gnawing. It does not stop growing, so they must chew to maintain and wear it down. Chewing on a variety of items available to them resulting to great damage in and around homes. Most rats, especially brown rat rattus norvegicus species are well-known for rapid breeding.

They constantly reproducing to maintain their large population. Example: Female can give birth to an average of 40 babies a year. When the condition is ideal, they can start conceiving again after 48 hours after giving birth. This is the reason their population gets bigger in a short period.

The Rodent Dietary

Habitats like whether they are in urban area, rural or the wild can affect their food sources. Roof rats, although omnivorous, prefer nuts and fruits. But ultimately, they will eat anything if they get hungry. They also tend to stash food at their harbouring area.

On the other hand, norway rats diet consist of literally anything cereal, meat and just about anything to survive. Meanwhile, house mice Singapore prefer seeds, nuts and cereal grains, similar, to roof rats and norway rats, they will eat anything. They can only survive at least 4 days without any source of food.


The house mice dropping are the smallest among the three. Just like their body size compared to the others. Rat control specialist can identify the type of rodent is infesting your home just by looking at the dropping size. Obviously, the bigger the rodent, the bigger the dropping size.


Rodents are bait shy for example, they will not eat a whole loaf of bread. And instead, will start chewing the packaging consuming small bites each time. You will notice evidence of multiple rat bite marks or chewing signs on the food packaging over time.

Live Presence

Rodents breed all year round and needs a well hidden nesting area for them to reproduce. It is also common for them to start shredding nesting material for their nest. Material such as paper, card board and even cushion sponge. You should be very alarmed when this happens.

Smear & Foot Prints
