What are the black dots that we can see on the walls of the house? A woman says that she saw some black marks that she had never seen before on the walls of her kitchen. she was scared and immediately took a picture of the wall and shared it on the internet.
Some people responded by telling her not to be afraid, the black dots could be spider excrement, when the woman heard this she was horrified. It has been scientifically proven that many people are irrationally afraid of spiders.
Her photo on Facebook received many comments and some friends advised her to clean the kitchen walls. But how harmful can the spider and its droppings be if they affect the food or the environment where we live? Spider droppings are liquid and leave marks.
They are usually brown and black. Many people in the world are very afraid of spiders and are protected from their venom. But scientists are trying to explain that there are animals or insects dirtier and more dangerous than spiders.
Spiders are not always poisonous and terrifying. They can be small and grow near the windows or in the corners of the walls. This usually happens in old houses or damp houses. Many people and scientists have many questions about spiders.
The answer about the black marks
A student decided to put an end to some of them. Therefore, a student who had finished his studies at Washington State University decided to study the level of danger in spiders.
The question which she studied was about pathogens that can grow in spiders. Do spiders have Staphylococcus spp., Streptococcus spp., Enterococcus spp., Salmonella spp., and E. coli, as do many other insects? Can we get infected with these pathogens if the spider comes into contact with our food?
So she analyzed the spider’s feces but did not detect any of the above-mentioned pathogens in the insect’s feces. So, according to studies of spiders, some antibacterial abilities attack these dangerous bacteria. However, the environment must always be kept clean and spiders must be removed from the interior of the house.
