"Metro Insect Refill 60 nights" refers to a specific product from the Metro Milan brand, which is a well-known manufacturer of insect control products in Pakistan. This product is a liquid refill for an electric mosquito repellent machine.

Here's a detailed breakdown of the product:

Product Type and Purpose

This is a liquid mosquito repellent refill for an electric vaporizer or heater. It is designed to be inserted into a plug-in device that heats the liquid, releasing an active ingredient into the air to repel mosquitoes and other flying insects. The "60 nights" claim signifies that one bottle is designed to last for approximately 60 nights of use, with each night typically being defined as 8 hours.

Key Features and Benefits

Long-Lasting Protection: The product is designed to provide continuous protection against mosquitoes for an extended period, making it a convenient solution for a full two months.

Effective Repellent: The formula contains an active ingredient (common ingredients in such products include Pyrethroids, though the specific chemical for this product is not specified) that effectively drives away mosquitoes, helping to prevent bites and the spread of mosquito-borne diseases like dengue.

Compatibility: A key selling point of many of these refills is that they are designed to be compatible with other brands' electric mosquito repellent machines, not just Metro's own heater.

Odorless or Lightly Fragranced: Many modern liquid repellent refills are formulated to be either odorless or have a very light, non-irritating fragrance, ensuring they are suitable for use in bedrooms and living spaces.

Convenient and Mess-Free: The liquid format is much cleaner and easier to use than traditional mosquito coils or sprays.
