Lagos…it is the city of possibilities. From careers to aspirations…
Cockroaches have always been insects that invoke fear and hysteria in many people even becoming the favourite ‘prototype’ for aliens in Hollywood. A few people actually love them and others eat them. Whatever side of the divide you are on, you should find this list we have prepared of the top questions people ask about roaches and their answers very interesting.
1. Where do cockroaches live?
Most of them live in wet areas like the damps, decaying surfaces, toilets, bathrooms, just anywhere wet but the brown-banded specie could live anywhere in the house especially the dryer, hotter places. The Americans hate cockroaches so much but guess where they live, in their restaurants.
2. What do cockroaches feed on?
When we talk about cockroaches, these insects could come in different species from the white one to the brown ones or from the Orientals to the Germans making some basic factors to vary. As for its feeding it varies because some could be selective, some eat any form of garbage, or wallpaper paste, book bindings, non-organic items such as toothpaste, including plants and other (dead) insects. Funny enough, American roaches have been seen feasting on pepper and onion before, we think because they just love hydrated food.
3. Can cockroaches be eaten as food?
Although Westerners may consider eating this insect as irritating, some other people see it as mouth-watering like the Chinese, Mexicans and the Thaïs. Most of the time this is prepared by removing the head, legs and sometimes internal organs. In China, people eat them toasted, fried, sautéed, or boiled and you can find roach delicacies prepared around many Chinese restaurants.
4. What are the health benefits of cockroaches?
According to a study conducted by the School of Veterinary Medicine and Science, researchers discovered that this insect’s head in its brain(cells and tissues) carries a powerful anti-biotic which is strong enough to kill 90% of MRSA and pathogenic Escherichia coli, without harming human cells and also a cream made from powdered cockroaches is used in some hospitals in China and Korea to trade burns and other facial injuries.
5. What is the economic Importance of cockroaches?
Let’s take for example in china even though the Westerners like the Americans are looking for ways to eradicate roaches, the Chinese have taking up the business of rearing them in farms (when I say rear I mean the same way you have your chicken reared) and according to them it’s a lucrative business.
6. How fast is the cockroach?
Looking at a crawling cockroach you might take it for a slow thing but if you’ve been desperate enough with your broom or shoe trying to kill a one before, then you can understand me when I say ‘speed power’. In the early 90s two scientists at the University of California, Berkeley conducting a speed test on roaches and an American specie was covering 1.5 metres (5 feet) in one second, achieving a speed of 5.5km/h (3.4mph). So what do I say to you? Before killing one aim well before striking or else…
7. How sharp is the sight of a cockroach?
Just like I said, these beings are hard to get, so you might wonder how come they are smart when it comes to running and hiding. Actually these insect possess a compound kind of eyes not like that of humans that captures clear pictures but instead the ones that traces motion, that is why whenever you turn on the light they kind of scatter or they sense you approaching they run simply because they care not about the prey but the food and probably predator . Interesting enough, that’s why they go for hiding when not in search for food.
8. The two antennas, what are those?
Most of the time you try to pick it by its antenna, careful cause you might be hurting its eye. Cockroaches uses those antennas in the form of a sight device, at the tip of this poles are tiny hairs which detects a minute air so helping it to notice the movement of an animal, presence of food and sometimes “smell” chemicals in the air.
9. Do cockroaches eat pepper?
Like i said before, they do. The world’s oldest pest, as researched by Imperial College London in 2010, does eat organic materials. They have existed before dinosaurs, and as an omnivore, they can eat anything including leather, paper scraps and even nylon clothing. Due to their digestive tract that possess a plethora of protozoa and bacteria aiding them to feast on non-food items. However, if no food is available, they resort to cannibalism.
10. Can cockroaches hatch without their mother?
Yes. This is because some roaches are ovoviviparous – the roaches grow in an ootheca – a sac where roaches carry their eggs, which is attached to their abdomen – inside the mother’s body. Although, in few species, the eggs grows in the mother’s uterus without being surrounded by an ootheca. Just as they would feed outside the body, the developing roaches inside feed on the eggs’ yolks. Additionally, most roaches are oviparous – whereby their young grow in eggs outside the mother’s body. The Pacific Beetle Cockroach is an example of a viviparous specie – producing live species as most mammals do.
11. Can cockroaches produce milk?
Diplotera punctata, also known as the Pacific Beetle Cockroach, produces milk crystals. These milk crystals contain three times more energy than buffalo, which were formerly the species producing a protein with the most calories. The milk contains everything from proteins, fats, sugars to essential amino acids. Making it a complete meal.
12. Can cockroaches survive frezzing?
Roaches need food and water to survive (more of the latter than the former), and even in an unfavourable condition as winter. They survive. And they do this by hiding in cracks, walls, shoes, behind appliances and even close to water sources. However, there are exceptions to this. An instance is the American cockroach that moves indoors whenever there is severe cold.
13. Can cockroaches survive a nuclear fallout?
Yes and no. Yes, because they possess the ability to withstand the heat due to their body design and slower cell cycles. The activity of cells increases when it is exposed to radiation by actively dividing. However, due to the fact that the average roach molts once weekly, and its cells divide within two days. It means that circa 75% of roaches exposed to radiation will not die, at least relative to the cells that are dividing.
No, because they can only survive it to an extent. After which they die off. If the nuclear radon units are high enough, say 100, 000 rads of Cobalt 60. They will die off. However, if at 1, 000 rads, they can still survive. In comparison to humans, 1, 000 rads can kill a person within 10 minutes.
14. How to control their spread?
Whenever I look at them or get sight of anyone of them, the first thing my brain asks me is “where on earth is your broom?” But seriously speaking there are cool insecticides out there in stores, just go get one and use them moderately or better still get a professional fumigator to help you out.
