The shelf life of pesticides varies depending on the type of pesticide and its formulation. Generally, pesticides can be stored for 1-3 years without significant loss of effectiveness if stored properly in a cool, dry, and dark place. It's important to check the label for specific storage instructions and expiration dates.

What are persistent pesticides?
Persistent pesticides are chemicals that remain in the environment and can accumulate over time in soil, water, and organisms. These pesticides do not easily degrade, which can lead to long-lasting environmental and health impacts. Examples include organochlorine pesticides like DDT and chlordane.
Does sea salt expire?
Sea salt does not expire, as long as it is stored in a cool, dry place away from moisture and contaminants. It can last indefinitely without losing its flavor or effectiveness.
How do pesticides contaminate groundwater?
Pesticides can contaminate groundwater when they are applied to fields and leach through the soil into the groundwater. Rainfall or irrigation can help move the pesticides deeper into the ground where they can reach the groundwater. Once in the groundwater, pesticides can persist for a long time and potentially impact drinking water sources.
How do pesticides get into rain?
Pesticides can get into rain through a process called atmospheric transport, where they evaporate from the soil, plants, or water bodies into the air and then get carried by wind currents. Once in the atmosphere, pesticides can be transported over long distances and eventually combine with water vapor to form clouds and then fall as rain containing pesticide residues.
How long should I freeze an ice pack for optimal effectiveness?
For optimal effectiveness, freeze an ice pack for at least 2 hours before use.
Can probiotics be frozen for long-term storage without losing their effectiveness?
Yes, probiotics can be frozen for long-term storage without losing their effectiveness.

How long does pesticide last on grass and what factors can affect its duration of effectiveness?
Pesticides can last on grass for varying lengths of time, typically ranging from a few days to a few weeks. Factors that can affect the duration of effectiveness include the type of pesticide used, weather conditions, application method, and the presence of other chemicals or substances in the environment.
How do persistent and non-persistent pesticides differ?
Non-persistent pesticides are compounds that break down quickly in the environment. Several different classes of pesticides make up this group: • Cholinesterase-inhibiting pesticides, which includes the organophosphates and carbamates • Chlorinated phenols • Herbicides • Pyrethroids • Fungicides • Repellents Non-persistent pesticides became widely used after persistent organochlorine pesticides were banned from manufacture and use in the United States in the 1970s. Non-persistent pesticides are less harmful to the environment because they do not build up but they have to be applied more often to households and crops to be effective.
Can a store kick you out without any valid reason?
Yes, a store can ask you to leave without providing a specific reason as long as it is not based on discrimination or violating your legal rights.
What are persistent pesticides?

How long does potting soil last in the bag before it expires or loses its effectiveness?
Potting soil typically lasts for about 1-2 years in the bag before it may expire or lose its effectiveness. It is important to store it in a cool, dry place to maintain its quality.
Who started organic gardening?
Long before there were synthetic pesticides and fertilizers, everyone grew organically. In modern times, organic became a label that is used for food produced without the use of synthetics.
Why are non-persistent pesticides more dangerous than persistent pesticides?
Non-persistent and persistent pesticides are equally dangerous, but non-persistent has immediate impacts whereas persistent pesticides wield long-term effects.Specifically, non-persistent pesticides include the super-powerful organophosphate malathion. They may impact people and wildlife for hours to weeks until they degenerate. In contrast, chlorinated hydrocarbons represent prime examples of persistent pesticides which survive for months to decades in the environment.It is the difference between immediate, sudden death or disability and long-term, protracted fatalities.
What is the shelf life of a Bic lighter and how long can it be stored before it may lose its effectiveness?
The shelf life of a Bic lighter is typically around two years. However, if stored properly in a cool, dry place, it can last longer without losing its effectiveness.
Can you get banned from a store without any valid reason?
Yes, a store can ban a customer without a valid reason as long as it is not based on discrimination or other illegal factors. Stores have the right to refuse service to anyone.
