Les nuisibles sont des insectes qui envahissent toutes sortes de logements (maison, bureaux, etc.) et présentent une menace au bien-etre, la sante publique et le environnement.
Cependant, les pesticides vendus dans la circuit de grande consommation n’ont pas suffisamment d’effet sur ces insects. Pourtant, leur utilisation excessivement impliques un niveau d’exposition que présente certains risques pour la sante et l’environnement.
Pesticides are the chemicals used to control or kill various insects, weeds and diseases. They include insecticides, fungicides, herbicides, rodenticides and growth regulators.
They are important in agriculture and help in improving the production. They are also useful in preventing the spread of diseases, which are harmful to human beings.
Ideally, pesticides kill only the target pest and not other nontarget organisms. However, they can have a negative impact on the environment and on people.
The toxicity of pesticides to nontarget organisms depends on several factors. These include how long the chemical stays toxic in the environment and how it is absorbed, moved and destroyed by other processes (e.g., runoff).
Pesticides have many benefits, but they can be hazardous to people and the environment if not used safely. They can also harm beneficial organisms, such as bees. These impacts are the main reasons why many people choose to use natural remedies instead of synthetic products.
2. Heat Treatment
The use of heat treatment is a great way to kill pests without using chemicals. This method involves gradually heating a space to high temperatures that are lethal to bed bugs and other insects at every life stage.
Unlike traditional pesticides, heat treatment leaves no residues behind in or around your home that could be potentially harmful to you or your family. This makes it a great choice for people who are concerned about the chemical exposure they would be exposed to, or those who simply want to avoid toxic chemicals in their homes.
It can also help you achieve a completely eradicable infestation in a single treatment. This eliminates the need for re-treatment in the future.
Before you have a heat treatment done in your home, you should take steps to prepare the area for the process. This includes unplugging electronics and removing furniture that could be obstructing the airflow or blocking the entry points for pests.
There are millions of chemicals on Earth — some occur naturally, and others are made by people. You probably use chemicals every day, such as chlorine (used for bleaching fabrics or in swimming pools).
There is also a wide variety of man-made chemical pesticides that are used to kill or harm insects, weeds, fungi and other creatures. Some of these include insecticides, herbicides and nematicides.
These chemicals are often more effective than organic alternatives, but they can cause environmental and health problems if not properly handled. You should always read the label and safety data sheet to be sure you are using them correctly.
The toxicity of chemicals is measured by their LD50, which is the amount of a chemical that it takes to kill 50% of lab animals in a test. Those with higher LD50s are generally more toxic, and those with lower LD50s are less toxic.
