Rodents

Rodents are among the most successful of all mammals, because they are extraordinarily adaptive toward their living conditions. In addition, they are capable of producing at a rapid rate thus making eradication program difficult.

Senses of smell and touch are crucial for rodent. These two senses are the key for their survival and help them avoid danger. Though rodents are keen with smell and touch, it does not mean that their other senses are less effective. Rodents are good with their hearing. Their eyesight enables them to forage at night and are highly sensitive toward predatorial movements.

They mark their territory along their food sources, and diligently search for new harborage areas to store food. They often harbor in covered places, warmth, and are close to their food source.

Some types of rodents have been known to live alongside human. They are acquainted with our living condition. With their highly adaptive skills, they can make most places their home. As a quick learner from past experiences and having good memories, rodents are known to be smart and cunning.

Rodents are known to chew their way in to find food. Rodents’ teeth are capable of tearing up iron, woods, copper, and aluminum. For this reason, traces of rodent’s infestation may come in forms of chewed electrical cords, air-con system malfunction, chewed plastics, chewed food packages, etc.

Success Stories from our Team

Where did the rat come from?

Our team received a call from a client that needs us to go investigate her condo. She wanted to know how did a rat entered her place. She insisted there was a rat in her room because the food was drag from its original place. There were chewing traces. The client informs the condo management team to which they called their pest control contractor. The contracting pest control confirmed that there was no rat, and no entrance that the rat could enter the room. The maid also insists that there was no way the rat could get in. The client, however, was suggested by her friend to call Virocare.

She called us for Virocare inspection program. Our staffs went in and found foot prints around the air compressor at the balcony. These foot prints led the team to believe that there is a pathway along the air-conditioning pipe. The pipe is connected to the client’s ceiling. However, when our staff check at the possible access point, he found that it was sealed shut. He couldn’t find the access point that the rat could take from the ceiling into the room. He rechecked the lighting system and still could not find any possible entrances. The other staff suggest that there might be a spot that the rat can use, but they were unable to check that spot. The spot is at the ceiling corner above build-in closet which the team couldn’t access.

Eventually our team decided to mix things up a bit. They attached a phone with a broom and turn on the phone camera so they could reach in and see into the space. They found the rat entrance there including foot prints indicating that it was the access point of the rat into the room. The client was happy with this finding, and recommend Virocare to some of her friends.

Chewed Electrical Wires in a Car

One of our clients suffered with rodent infestation. A rat got into his car and chewed the car’s electrical cords causing an expensive damage. The car was repaired with the cost of six digits figure. He also told us that, they (rodent) dug around his lawn, and burrowed under his house. It was a nuisance thus he called Virocare.

Our team went in to investigate and let him know some of the risk areas and possible entrances. His garage, when close down, wasn’t completely closed causing a small space between the ground and garage door. This small space is the entrance the rat use to enter his garage. The client fixed this problem and also other possible access point for rats. When all the risk were fixed, combined with Virocare rodent eradication program, the rodent problem was reduced significantly. After 6 months, the house was rodent-free.

Caused by trees

A client found rodent infestation in his house. When inspected, our team found there were sewer rat and roof rat activities in the vicinity. Surrounding the house were trees with one of them around 3 meters tall. The tree branches were long overarching the house roof. Our team informed the client that the tree branches were the pathway that rats use to access his house. Our staffs installed bait stations around his house, especially at the bottom of the tree. Later on, the client called and told us that he cut down those trees down which quickens a positive outcome. Combining with Virocare rodent eradication program, after two weeks the client feedback to Virocare that he continuously found dead rats. This went on for about 2 months, and after that his house was back to peace.

"I used to have small cockroaches in the apartment. They lived in drawers and cupboard. The juristic offers pest control service, too, and they come into solve our cockroach problems. The problem still exists. My girlfriend called Virocare. The team arrived and inspected our place. They told us the problems we were experiencing. They found eggs; cockroaches’ egg and the younger generation cockroaches that probably just hatched. After the first service treatment, the number of cockroaches reduced significantly. The service team puts several cockroaches traps in our apartment to check the pest population. These traps, we also used before they carried out service. They were always full with roaches. After the treatment, we saw the difference this time. We found the number was far less than what we had encounter. The big ones still existed, but in a much less number, less than 5 (from more than 20). The team came in once more for a follow up session. After that our apartment was roaches-free. Since we chose one-time service, after the follow up session, we still use the roaches trap to keep our eyes on them. Surprisingly, they didn’t come back. We were very happy with the outcome."
