There are more than 120,000 species or types of flies in the world, and 18,000 of these species can be found in North America. Although they only live for about 21 days in total, female houseflies can lay up to 600 eggs in their lifetime, and female fruit flies can lay up to 500 eggs in 8-10 days of life. It's no wonder that when these pests invade, there seem to be so many of them! Although houseflies and fruit flies don't bite, they are quite dangerous and can carry over 100 harmful bacteria that can make us seriously ill.

Sometimes flies can seem to show up without any warning signs, so where do they come from and how do they get into our home? Read on to learn where to find them and how to get rid of these pesky invaders.

Where do flies lay their eggs? 

Flies can lay eggs in trash cans, compost heaps, excrement and rotting organic materials. Female flies can lay between 75 and 150 eggs at a time, which when mixed together is about the size of a pea! Due to their small egg size, flies are extremely difficult to identify, and before you know it, you have a fly infestation (or a big problem)!

The housefly is the most common type of fly found in and around our homes. Houseflies are so common because they reproduce quickly and in large numbers, making them difficult to get rid of! They are sometimes known to move up to 20 miles from where they hatched, but usually these flies stay within one mile of their birthplace. They typically hatch outside and then enter homes through weak points in the structure, such as damaged seals or torn screens covering windows and doors.

Fruit flies are also common in homes due to their attraction to food waste, such as rotten fruits and vegetables, or drains clogged with rotting food. Fruit flies often enter homes as hitchhikers on produce brought in from outside, and can also be found in trash cans and compost bins containing rotting fruit and vegetables.

How to get rid of flies? 

House flies usually do not breed inside because they enter homes from the outside, but flies often travel from inside the home into trash cans and compactors. This creates the perfect environment for them to breed inside. For this reason, it is important to ensure that all rubbish bins are kept clean and that waste is disposed of regularly. Throwing away fruits and vegetables before they rot will protect them from fruit flies, and it's also important to keep your kitchen clean.

You can help prevent fly infestations in the first place by throwing out trash regularly, closing all trash cans, disposing of pet waste immediately, and making sure all windows and doors are free of scuffs and tears.
