Fly paper is an effective way to control flies. These strips are made of sticky material and should be hung in areas where flies are most likely to hang out. However, the flypaper should be changed every few days because it gets dusty and can lose its effectiveness. The strips are effective only when flies are trapped inside them. It is recommended that you do not hang flypaper on walls or near pets or children.
If you are not sure if the insect repellent you are using has reached its expiration date, you should call the manufacturer. Calling the manufacturer is usually the best way to find out if the product is still effective and how long it has been in the shelf life. Moreover, the expiration date is not a set number but depends on the ingredients and brand.
Fly paper is made from sticky paper that contains aromatic, sweet or noxious substances that attract flies. It originated in the days of horse-drawn carts and was available in local drugstores. The advantages of using flypapers included their convenience, affordability and disposal. The invention of glue boards was also based on flypapers.
