Achen, the person in charge of the pest control company “German Bass Pest Control” shared a case of pest control. About six months ago, he received help from a young man and woman. A few weeks after they returned to Hong Kong from traveling in South Korea, they were suspected of being bitten by insects in their sleeping room. There were bed bugs, so I entrusted him to come and deal with them. Ah Chen said that he came to the house and found a lot of bed bugs in the house, but they were only concentrated in their bedroom. The other elderly person’s room was completely free of bed bugs. In addition, the bed bugs had not yet entered the wall, so he believed that they had just entered the house for about 2 hours. to 3 weeks.

As for the source of bed bugs, since the victim did not shop online during that period, it was ruled out that bed bugs entered the house with the package. Considering that their time coincided with their return to Hong Kong from travel, and the scope of the bed bug infestation was limited to their room, Achen concluded that bed bugs There is a higher chance of bringing it back to Hong Kong from South Korea, and it is believed to be related to the luggage.

“When they arrived at the house, the suitcases were put directly into the room without being processed. They may have brought bed bugs and bed bug eggs directly in.”

More than 30 lice infestation inquiries per day

Achen pointed out that the company has recently received an increase in the number of cases seeking help for lice control. Information inquiries alone accounted for 30 to 50 cases every day, and many of the seekers had traveled abroad. However, Achen believed that most of the cases were actually not ” “Imported cases”, even if citizens return to Hong Kong after traveling and find lice in their homes, they may not have been brought back to Hong Kong from abroad. He said that when determining the source of bed bugs, factors such as the incubation period, degree of spread, living habits, and whether there are high-risk groups in the home (such as the elderly or foreign domestic helpers) should also be considered.

Do not drag suitcases directly into the house after returning to Hong Kong

Achen continued to point out that in fact, the local community has always had a problem with bed bugs, and he believes that the risk of contracting bed bugs when traveling abroad is smaller than being “infected” locally. He also pointed out that bed bugs actually have a “memory”. When they are used to sucking blood in hotel rooms every day, they will not risk crawling into luggage bins to transfer sites unless they are stimulated by other factors, such as guests spraying insecticide water indiscriminately. Secondly, female bed bugs carry eggs and hide them everywhere. Unless eggs enter the suitcase, or the female bed bug enters the suitcase to give birth, bed bugs may not necessarily spread with the suitcase to other places. However, for safety reasons, he suggested that after returning to Hong Kong, you should spray your luggage with steam or alcohol before entering the house, and wash the clothes in the luggage as soon as possible. If you cannot wash it immediately, you should wrap it in a plastic bag.

10 Bed Bug Black Spots

Ah Chen also explained that the reason why bed bugs are “difficult to deal with” is usually because residents fail to detect and deal with them immediately, causing the bed bugs to spread quickly. In particular, the elderly do not feel obvious after being bitten by bed bugs, so they may not know what they are causing. It is infested with lice, so it is difficult to dock the tail. As for outbound travelers, they are generally younger and more sensitive to itching, so they will detect bed bugs earlier and deal with them faster. As for bed bugs, they tend to hide in specific locations after entering the house. Here are 10 home bed bug black spots:

Bed bugs should be killed with high temperature

Ah Chen shared earlier that under normal circumstances, bed bugs and their eggs will die when exposed to high temperatures of 60 degrees Celsius or above. It is recommended that if the public suspects that they have encountered a lice infestation, they can try to use high-temperature methods to kill lice, which is the most effective. , the impact on human body and economic cost are also low.

Take clothing as an example. Washing clothes with hot water can kill bed bugs. As for mattresses and quilts that are difficult to wash, use a regular steam iron or steam iron to kill bed bugs. However, he reminded that high-temperature methods can only be used for relief. Since bed bugs reproduce quickly, if the problem is serious, it is best to hire a professional pest control company to deal with it as soon as possible.

DE powder should be poured into a spray bottle and added with water before use

As for the majority of people who use diatomaceous earth (DE powder) to kill lice, Achen pointed out that many people will use a spoon to scoop up DE powder and sprinkle it on the ground. However, this method is difficult to put in accurately, and on the other hand, the powder is easy to fly up. So choose the right delivery tool.

Achen emphasized that even if the manufacturer claims that DE powder is a food-grade material, there is still a chance of causing harm when the powder is inhaled into the respiratory system through the mouth and nose. Therefore, the safer way is to pour DE powder into a spray bottle and then mix it with a small amount of water. , when the water evaporates, the DE powder will still stick to the surface of the object, exerting its insecticide effect, while preventing the powder from scattering and causing discomfort after inhalation. However, it should be noted that this method should not be used in locations with sockets, otherwise there is a risk of leakage.
