How to Prevent Rodents from Coming Into Your House

As the Coronavirus infected more people day by day, one person from southwestern Yunnan province passed away after contracting the Hantavirus. In 1993, the virus was first reported in the U.S and is transmitted to humans by rodents such as mice and rats. However, it does not easily pass between humans and only be caught through contact with the bodily fluids and excrements (urine,feces,saliva) of the rodents that sometimes can cause potentially fatal disease in humans. Until now, there is no WHO-approved Hantavirus vaccine available, therefore preventive measures must be taken in order to reduce your risk of contracting this virus.

Rats and mice are rodents that give rise to the most common and serious pest problems in Malaysia. This is due to the poor public sanitation and the abundance of their primary diet which mainly consists of disposed of food found in the trash of homes, restaurants, shopping centers and even hospitals.

There are 2 types of control methods to prevent rodents from coming into your house.

Physical Control 

  • All holes and cracks on the walls and ceilings should be sealed up to prevent the entry of rats.
  • Door gaps and windows should be closed by using door-seals or door-sweeps.
  • All air ventilation systems in the bathroom and kitchen should be covered with mesh screens that make it inaccessible for any rats or mice.

Chemical Control

  • Eliminating rats and rodents can be done by using rodenticide which acts as baits.
  • The baits should be kept in a small holed container to prevent children or pets from accessing them.
  • Outdoor baits must be placed inside a plastic wrap to prevent them fromrain and shine.

Chemical Control

Indoor Control

RIDPEST uses toxicant rat baits that contain anti-coagulants which triggers the blood to clot and blocks the effectiveness of vitamin K, preventing blood clotting.  Usually, the rodents upon consuming the bait will die within 4 – 10 days from internal bleeding.

Rat baits installed Indoor

For indoor areas, 3 blocks of rat baits will be placed. The baits are properly placed (under or behind furniture or inside a cupboard) out of sight from infants or pets.

Outdoor Control

For outdoor control, a rat baiting system is known as Tempered Rat Bait Station (TRBS) will be used. The station is made of PVC that comes with a secure lock. The station comprises of ‘first line defense’, ‘second line defense’ and ‘third line defense’ placed along the perimeter of the premises.

Cylindrical TRBS with Lock

First line defense is a system where the cylindrical TRBS are put along the fencing areas around the premises.

 Square TRBS

Second line defense comes in the form of square TRBS placed against the outer wall edge around the premises.

Third line defense also comes in the form of square TRBS placed around the inner wall edge of the premises.

At least 3 blocks of rat baits will be placed inside the stations. The baits are monitored and will be replaced regularly. The number of baits consumed and the presence of rodent feces; if any, will be recorded. The recorded data will give information on the heaviness of the infestation.
