It is highly unlikely that fleas will go away on their own without treatment. Female fleas can lay dozens of eggs per day—up to 50—causing their numbers to multiply quickly and spread throughout your home. An adult flea can live for around 100 days or even up to a year as long as it has access to a host, such as a pet or human. Even without a host to feed on, fleas can survive for weeks. Because of their rapid reproduction and resilience, it's best to tackle a flea problem as soon as possible. Hiring an exterminator is recommended to prevent the infestation from worsening.

Having bugs in our houses is quite normal. However, if you notice a sudden uptick in quantity, there's often a reason behind it. Seasonal weather changes, particularly warm to cool, drive bugs indoors as they look for comfort. Structural damage to your home can open up new ways for them to get in, and a new water leak somewhere in the house can invite them to get comfortable.

There's anecdotal evidence that apple cider vinegar does help to repel mice. But the best way to repel mice is to keep your home scrupulously clean and seal up any obvious entry points. If you already have a mouse infestation, apple cider vinegar won’t get rid of the critters. It’s usually worth the cost of professional pest control to make sure a serious mouse problem is eradicated completely.

Although weevils aren’t harmful to humans, it’s best to throw out flour (or any food product) if it contains weevils or other pests. However, if you want to salvage food after finding pests nearby in the pantry, you can freeze it for at least four days. To prevent weevils from returning, make sure to store your food in airtight containers or inside your refrigerator or freezer.
