Its great capacity to adapt to environmental changes make cockroaches the most successful insects of survival of the planet, and therefore, also one of the most complicated pests to control in homes and businesses.
How are they introduced in the Houses?
Cockroaches can be introduced into the house by different means: hidden inside bags, packages, cardboard boxes, egg cups, or infected appliances, sneaking from the outside through cracks or holes in doors or windows or through drains, or moving from one home to another by pipes, wiring or shared walls.
The main reason why the introduction of cockroaches at home goes unnoticed is because of their nocturnal activity. When they remain inactive during the day, the probability of being able to observe them entering the home is very low.
Cockroaches do not just enter dirty houses
There is a false belief that cockroaches only invade dirty homes or homes, so many people find it hard to recognize that they suffer from this plague in their homes. While it is true that the lack of hygiene is a great help for these insects to reproduce explosively, it must be made clear that this is not the reason why they enter homes.
A cockroach only requires water, food and a warm temperature to settle in a house, so any house is susceptible to suffer its annoying presence, regardless of how clean and orderly it is. However, keeping the house clean and tidy is one of the keys to control the levels of infection and prevent them from increasing exponentially, since it allows limiting the amount of food and shelters available, and therefore, stop their multiplication.
Cockroaches reproduce very quickly
One of the reasons why cockroach pests in homes are so difficult to control is their great potential to reproduce, which allows them to multiply their number in a few days.
Thus, for example, in the case of the German cockroach (Blattela germanica), one of the most frequent cockroach species in infested houses, a female can have 4 to 8 beetles throughout her life, of which, they appear between 30-48 nymphs in just 28 days. This results in:
This taking into account that each one of the females reproduces only once, and that the invasion is produced by the introduction in house of a single female.
These values give us an idea that it is really important to recognize and treat the problem of cockroaches at home at the first sign of infection, since the control of the plague is complicated by the increase in the number of individuals.
Signs of a plague of cockroaches at home
Its presence, unless the levels of infestation of the house are very high, goes very unnoticed because its activity is concentrated during the night.
The most unmistakable traces of the presence of cockroaches at home are the marks made by the jaws during feeding on any type of surface: pasta, food, book bindings, paper, glue, rubber, etc.
In the same way they are the presence of excrements (also known by the German term “frass”), which has the form of black powder and which they leave in any frequented place.
Another element that can help detect a plague of cockroaches is the presence of discarded skins and ootheca, which are like small elongated cases of reddish or black color depending on the species, and inside which the cockroach nymphs develop.
They can also be detected by looking for individuals directly, under appliances, behind laundry rooms or in dark and wet cracks or crevices.
In any case, in the presence of cockroaches at home, and taking into account their great capacity for survival, the best solution to effectively end the plague hide with one of our experts in pest control.
