Why Are Dead Cockroaches Always Flipped on Their Backs?
Have you ever noticed something strange about a dead cockroach that you saw in your house or your office? The cockroaches always lie on their backs with the legs in the air. The majority of the population thinks that this position is accidental but there is some real science behind it. The backward death of the cockroaches is not accidental, but it is also the effect of biology, physics, and even pest control products. Now, we shall see what is all this queer stuff.
The Role of a Cockroach Body Structure.
An exoskeleton is the hard outer covering of the cockroaches. This structure offers protection but also limits flexibility. Their bodies are a little rounded and the back is a bit more rounded than the under. Once a cockroach has lost his balance, due to poison or fatigue or injury, it becomes far easier to roll on its rounded back, than to remain on his belly.
Having fallen down, the cockroach has a great difficulty, to stand up again. Its long spiny legs are ideal in running over smooth surfaces but they are not designed to push off the ground when lying on their back. The insect is held in the same position without muscle coordination or traction which causes it to die in that position.
Loss of Muscle Coordination
Developed cockroaches are fast, stable, and nimble. They are motioned by intricate muscle coordination to move, climb and position themselves. Nerve impulses are impaired when an individual is poisoned or it exposes them to insecticides, resulting in spasms and loss of motor control. The cockroach may jerk and kick then roll forward on its back. The nervous system is further affected by the poison which causes its leg and body muscles to stiffen in that position which is upside-down until it is frozen.
Put differently, cockroaches do not make a choice to die on their backs, but rather it was their malfunctioning nervous system that leaves them with no choice. This reaction is directly caused by the neurotoxic nature of most of the modern insecticides.
Insecticides and Their Effect.
The current products used in pest control such as sprays and gels usually contain neurotoxins. This type of chemical paralyzes the insects by obstructing nerve to muscle signals. When a cockroach comes into contact with these materials, it becomes uncontrollable, turns over and gets stuck.
This reaction is in fact an indication that the product is being effective in professional treatments of pests. In case of the application of insecticides by the technicians of Speedy Pest Control, cockroaches that are exposed to the chemical will normally be overexcited and become paralyzed. Their muscles will contract uncontrollably making them fight violently, roll onto their backs and end up dying in that position.
Cockroaches are not the only insects to have this symptom. The same reaction to neurotoxic treatments can be observed with other crawling pests (beetles and crickets) but cockroaches are the most noticeable pests because of their body shape.
Gravity Makes It Worse
Other than the state of biology and chemistry, gravity also has a significant role to play. A cockroach can only go on its back and gravity acts against it. Its body does not shape in such a way that the weight is distributed equally. Its center of gravity is high and thus its upright rolling back is hardly achievable without momentum or muscular force. The roaches are able to twist and push themselves in case there is enough traction but a dying or poisoned one is unable to do so. In due course, the cockroach remains so until death, due to the force of gravity.
This is further complicated by the smooth indoor floors in either the house or the office. The insect has nothing to hold on to and its legs merely keep swirling in the air in a futile attempt to invert. Cockroaches usually find a way to flip back on coarse surfaces such as soil or concrete, but in the house, smooth flooring ends its existence.
The Factor of Dehydration and Exhaustion.
It is known that cockroaches can survive weeks without food, however, they dry up easily when they are intoxicated. As a cockroach dies, it spends the remaining energy reserves attempting to get away or to stand on its feet again. It is no longer able to generate movement as dehydration and exhaustion wreak havoc. This is another reason why you will find them to this day, inverted, and immobile.
Dehydration is also hastened in hot, stuffy conditions and this is the reason why dead roaches are usually found in places where there are heat or in the dry corners of kitchens and bathrooms. Their death is accelerated by the exposure to air and absence of moisture.
Upside-Down Cockroaches Myths.
Some misconceptions exist regarding the reasons behind such death of cockroaches. Other individuals believe that cockroaches roll because they are protecting their vulnerable undersides or warning others that they are in danger, but it is false. Cockroaches do not get the control of their dying moments. The upside-down posture is strictly mechanical, and it is brought about by an imbalance and poisoning, and gravity.
The other myth is that they die in this manner only when insecticides are used to kill them. Although this is more common with the help of chemicals, cockroaches also perish on their backs of old age, injury or accidents which hamper their coordination abilities.
What It Means for Homeowners
Even finding dead cockroaches with particularly their backs raised can be a good indication during pest control. Generally, it implies effectiveness of the products. Nevertheless, their frequent observation might as well signal a bigger infestation issue. Cockroaches are fast multiplying and on every dead cockroach you see, there could be more than that in the shadow.
When dead cockroaches keep showing up, then it is time to call in an expert. Experts in Speedy Pest Control also employ specific techniques in finding areas of nesting, eliminating the cases of the eggs and administering a remedy. This makes certain that not only the visible ones but also the colonies of pests that are not visible are completely eliminated.
How Speedy Pest Control Can Help
At Speedy Pest Control, we don’t just focus on killing visible pests; we ensure they don’t come back.
