What will keep the Cluster Flies away?

One of the most effective ways to get rid of cluster flies is to hire a professional exterminator. Pest Control companies like Birch Fumigator have access to powerful insecticides that can quickly eliminate an infestation. Exterminators will also be able to identify potential entry points and take steps to prevent future invasions.

If you find cluster flies in your house during winter, they are likely already overwintering within your home. You can use a vacuum cleaner to remove visible flies. It’s also a good idea to inspect your home for potential entry points and seal them. Sometimes, especially if the infestation is large, you may want to contact Birch Fumigators for a more comprehensive treatment. Additionally, using light traps in areas like attics or basements can help manage the population until the weather warms up and the flies naturally leave the building.

If left untreated, cluster fly infestations can recur annually, becoming more severe over time. Continuous presence can lead to staining from droppings and an ongoing nuisance. Additionally, neglecting the problem may signal a lack of maintenance, potentially affecting property value and perception in commercial settings.

Natural remedies, such as essential oils (e.g., eucalyptus, lavender, or peppermint oil), can act as deterrents but are usually less effective than professional treatments. Light traps and sticky traps can also be used to capture flies. However, for large infestations, these methods may not be sufficient, and professional intervention might be necessary.

Weather and seasonal changes significantly affect cluster fly activity. They are most active in late summer and early fall when they seek shelter for overwintering. Warm, sunny days during winter can also stimulate activity within buildings. Understanding these patterns helps in timing prevention and control efforts effectively.

Cluster flies typically enter buildings through small openings around windows, doors, siding, eaves, and roof vents. Sealing these entry points is essential in preventing infestations. This can be done using caulk, weatherstripping, or screens. Paying particular attention to south and west-facing walls, where flies are most likely to enter, effectively sealing off entry points.
