Cockroaches usually become a problem when they invade areas such as the kitchen, bathroom or bedroom. Getting rid of them is a challenge, because they thrive in humid, warm places where dirt can accumulate.
Many tricks to get rid of cockroaches include a simple ingredient: sugar. Here we explain why insects hate it and how they learn to avoid it, according to studies.
A study published in the journal Science revealed that German cockroaches, one of the most common types of cockroaches in the world, have learned to avoid sugar. This finding may have important implications for pest control, since cockroach traps often use sugar as bait.
The study, led by Coby Schal of North Carolina State University, examines the evolution of sugar aversion in cockroaches.
What was found?
Researchers discovered that cockroaches exposed to traps containing glucose, a type of sugar, developed an aversion to this compound.
Sugar-averse cockroaches use tiny hairs to taste food and reject it if it contains glucose. When cockroaches eat glucose, a chemical reaction occurs that triggers an alarm signal in the insect’s brain. This signal causes the cockroach to avoid glucose in the future.
“They retreated as if they had been electrocuted. This is very, very, very obvious behavior. They absolutely refuse to enter it,” said Shacl, a professor of entomology.
Are cockroaches intelligent?
The study by Schal and his colleagues suggests that cockroaches can learn and adjust quickly to changes in their environment. This may explain why these pests have become so difficult to control.
Of the 19 types of cockroaches under study, seven showed rejection of glucose. “It’s a global phenomenon. It’s not limited to the United States,” he said.
The findings of this study suggest that cockroach traps that use glucose as bait may become less effective in the future. Also, it emphasizes the importance of pest control research. As cockroaches evolve, new strategies have to be developed to fight them, as is the case with other insects.
How to avoid cockroaches at home?
Cockroaches are common pests that can cause health problems and property damage. It is important to take steps to prevent cockroaches from entering and spreading in your home.
Sources such as the special site ‘Hogarmania’ give their best recommendations to prevent the appearance of cockroaches at home, such as keeping everything clean and free of food and water.
Another important point is to seal the cracks and gaps to prevent it from entering. Cockroaches prefer humid environments, so it’s important to keep your home dry. This includes drying dishes and utensils after use, as well as properly ventilating your home.
You can clean all the corners of the furniture and places that these animals can easily see with vinegar and lemon; Additionally, you can add bay leaves or garlic paste.
