Cockroach

Cockroaches come in dark brown and shiny black colors.

Cockroaches appeared on the face of the earth approximately 400 million years ago and, in our country, 644 species are known, most of which inhabit forest environments. Approximately five species of these insects are associated with urban environments and, therefore, present in human dwellings in different regions of the globe. Here’s how this little animal is classified:

Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Blattodea
Family: Blattidae
Genus: Periplaneta
Species: Periplaneta americana

The sewer cockroach, or flying cockroach, Periplaneta americana , is one of the most common domestic species in our country. This animal can live in various environments, preferring more isolated, warm and humid places. Baseboards, cracks, corners, cracks, drains and grease traps in our homes can shelter these beings whose presence is not very welcome.

These animals are more active at night, when they leave their shelters in search of food, usually rich in sugar and/or fat, although wiring, boxes and clothes can also be part of the diet, unfortunately. Surprisingly, individuals of this species are able to go up to 15 days without feeding.

Oval and flattened body, approximately 50 mm long, coloration that can vary between black and brown tones, short head, antennae and large and compound eyes are part of the morphology of this animal.

As for reproduction, cockroaches lay approximately 15 eggs in a capsule called ootheca, being able to carry it for up to 24 hours, depositing it in generally warm and humid shelters. The incubation period is approximately 30 days, until the nymphs are born, which are wingless and sexually immature. It takes between 9 and 19 months for an individual to be fully developed into its adult form, and it will be able to live for up to three years, giving rise to an average value of 800 individuals during this period.

Cockroaches are responsible for transmitting a range of diseases: gastroenteritis, such as salmonellosis and dysentery; infections, allergies, verminoses, mycoses and amoebiasis. The control of these species, removing their possible shelters and food sources, is necessary. Hygiene measures such as isolating the garbage, keeping the yard weeded and free of garbage, eliminating cracks, gaps, baseboards and stops, keeping food in safe packaging and applying insecticides are some examples of what can be done to control the proliferation of this insect. .
