Bedbugs, an Emerging Pest

Bedbugs are parasites that feed on human blood, and one of the most unpleasant insect pests you can have in your home. Bedbugs are cryptic and nocturnal, which means they spend most of their time hiding in small spaces, and come out at night to feed. While this pest comes in several varieties, the common bedbug, Cimex lectularius, is the most common species to invade our homes.

Bedbugs are attracted to the carbon dioxide produced by respiration, and also to your body heat. They are mainly active at night; however they are still able to bite during the day if given the chance. A single bedbug can bite a few times while feeding, with around 3 or 4 bites occurring in less than 10 minutes. These bites often form a straight line, which is called the ‘breakfast, lunch, and dinner’ pattern. Bedbugs can live up to a year without feeding, but they will look for a meal once every couple of days.

Bedbugs have been unwanted visitors in our homes since antiquity. Only in the 1930s did we make significant headway against this pest with the development of the pesticide DDT. With DDT, we were able to eliminate bedbugs from most parts of the developed world. After DDT was banned, bedbugs began to resurface as a common pest. Bedbug bites and their complications began to increase in frequency.

These bites cause an itchy rash in most people; however blistering or more serious allergic reactions are not unheard of. It’s also common to experience sleep disturbances and increased stress.

Fortunately, bedbug bites are unlikely to cause serious illness. Scientific studies have shown that they carry a variety of bacteria (including some with antibiotic resistance), but so far there has been no link to disease. Nonetheless, you’ll probably want to wipe out bedbug infestations as quickly as you can.

The hidden truth about bedbugs is that they emit a chemical signature that specially trained dogs can detect. A pest control agency might bring one of these dogs to your home to help confirm the presence of these pests. Once the source is found, the inspector needs to search the area to visually identify the bedbugs.

Once you have confirmed that there is a bedbug infestation, you’ll have a number of ways to eliminate them. Pesticides are not always an option, as some pesticides are harmful if sprayed on clothing, bedsheets, or surfaces that may contact your skin. While it may be necessary to fumigate your home, the hidden truth about bedbugs is that they are sensitive to high temperatures. One effective way to eliminate bedbugs without using pesticides is to heat the room to 57°C (135 °F). This requires special equipment, but is sure to produce results.

The most important tool used to keep bedbugs from spreading is awareness. Since this pest has been uncommon for a few decades, not everyone is familiar with the signs of an infestation. If you eliminate bedbug infestations quickly, they won’t be able to spread to the homes of your family and friends.
