Bed Bug bites usually show up in patterns, such as the ones seen in the images below. The bites from bed bugs are usually in a triangular pattern consisting of three or four bites. The bites can also be in a straight line. Despite bed bugs biting into the skin, they do not carry diseases. The following link discusses different types of common bug bites and how to identify them. Types of Bug Bites



Bed bug bites usually result in intense itching. This is because bed bugs inject an anesthetic-like substance into an individual’s skin before the bite. Bed bugs usually bite at night, hence why people wake up itchy the next morning. If someone suspects that they have been bitten by bed bugs, it is important to resist the urge to itch the affected area, as this can lead to secondary infections and other complications.


Some individuals may not react to a bed bug bite. Therefore, it can be difficult to notice any bites at all. Indeed, there are many cases where bed bugs crawl between the mattress and the box spring, so they are not easily visible. In these cases, the only way to determine that there are bed bugs in a household is to do a thorough inspection. Another option is to hire a k9 dog inspection for bed bugs. You can find more info in the following link. K9 Inspection


A common pattern recognized is bed bugs bite in a triangular shape. The triangle pattern consists of three bites, therefore creating that triangle shape of bites on a person’s skin. However, the triangular pattern is not always an exact indication of bed bug bites. It is a good idea to call your doctor but make sure to be referred to a dermatologist. Also, please call Green Heat Bed Bugs Exterminators to get an opinion as well. With an in-person inspection and/or k9 dog inspection, the residence can be inspected accurately.

Where Do Bed Bugs Bite?

Bed Bugs prefer to bite exposed areas. These small pests love to bite at night when the individual is asleep. Any spot on someone’s body, which is easily accessible, is prone to bed bug bites. Many households have pets such as dogs and cats. However, bed bugs do not prefer to bite animals, as it is very difficult to penetrate the skin of animals. The areas of the human body that bed bugs prefer are as follows; Neck/Face, Arms, Hands, Shoulders, Back, and Legs.



Bed Bugs can pose some health risks to humans. While bed bugs do not carry or transmit diseases, their bites can cause redness, itchiness, and swelling. It is important not to scratch the bites as this can lead to secondary infections. This, in turn, lengthens the process of healing. Additionally, individuals who are allergic to bed bug bites can experience more aggressive reactions. It is also important to seek medical attention if the bites get worse or if someone suspects they have an allergic reaction.


The first reaction of a bed bug bite is usually itching and irritation. This is often followed by a swollen reddish mark on the affected area. Bed bug bites can cause different reactions in different people. Some notice them instantly and for some it takes days. It is important to try to avoid scratching the affected areas, as this may worsen the itchiness and swelling. Always vacuum and clean regularly to contain the infestation.


Firstly, try not to scratch the affected areas. Secondly, wash the bites with warm, soapy water. To help with the itching, apply over-the-counter anti-itch creams such as calamine lotion. In rare cases, prescription-strength medication may be required. Consult a physician immediately if the bites are severe, as this may result in an allergic reaction.
