Bedbugs scientifically called ‘Cimicidae’ are insects that belong to the order of ‘Heteroptera’ and prefer human blood as their main food.
In the case of strong infestations, bedbugs are also capable of attacking domestic animals. The size of these pests is so small that they do not exceed 8 mm in length when grown up.
Their body is similar to that of ticks and, like this other type of parasite, they have a swollen belly if they have just fed, while they appear flat if they are fasting.
The parasites have six legs equipped with excellent anchors and good mobility and allow them to move skilfully towards their favourite place, i.e. objects adjacent to the bed.
But it is not only the pillows and mattresses that are the places where the bugs nest, who also love to hide behind paintings, under the skirting boards raised from the floor and in the under beds.
The bugs are lucifugal, that is, they tend to come out of their hiding places when they are not noisy and there are no significantly bright light sources.
Bedbugs have a reddish tinge when they are fasting but their colour changes when they are fed blood and becomes much darker.
They produce white, transparent eggs and are capable of nesting in places that are very difficult to locate and reach using ‘homemade’ methods.
How and when does the bug bite?
The bug’s meals take place about every 4/5 days but the rule is not fixed. As mentioned above, the bug feeds on human blood and sometimes on pet blood.
To do this it uses the ‘rostrum’ an organ of its body very likely to be a needle syringe with which it pierces the skin and injects an anesthetizing substance which is contained in the insect’s salivary glands.
This substance numbs the point on the epidermis on which the bedbug intends to act and then quietly sucks the blood for a time ranging from 2 to 3 minutes.
What are the consequences of the bedbug bite?
Many times the unsuspecting victims are not even aware of this ‘bite’, but people suffering from allergic diseases are at risk, because with this inappropriate bite they may have not exactly pleasant effects such as inflammation and redness of the skin, but also asthma or general illnesses that are not easily diagnosed.
Unfortunately for humans, parasites may be carriers of diseases acquired during their previous stings on other subjects.
