Insect infestations are pretty frustrating to deal with- they take a lot of time and your hard-earned money to properly eradicate the pest from your home. Many people experience the frustrating reality of moths in their homes, especially in the summer months.

Whether there are several holes in your favorite sweater or a rush of flying moths when a pantry is opened, moths can cause a huge nuisance.

However, only the moth larvae are responsible for the destruction in your home.

However, there are many effective ways through which you can prevent these moths from breeding and snacking in your home again.
