6 Super Effective Ways How to Keep Flies Out of Garage

Fortunately, there are several effective ways you can protect your garage from these pesky insects. Here are some of the most effective methods for keeping flies out of your garage.

Caulk and Seal Cracks and Gaps

First, you should thoroughly check for any cracks or gaps in your garage’s walls, windows, and doors. If you find any, caulk them up immediately, as these can provide easy access for flies. You should also seal any other openings around the garage that could let flies in.

Caulk and Seal Cracks and Gaps

You should check window sills, door frames and weatherstripping, vents, plumbing pipes, and electrical outlets. The smaller the opening, the more effective your barrier will be. Check around the edges of the doors and windows and any vents or pipes that enter your garage from outside.

Install Screens on Windows and Doors

Installing screens on your windows and doors is the best way to get rid of flies in your garage. This will block the entrance points for these annoying insects and help keep other pests like mosquitoes out. To provide maximum protection, use tight-weave screens and ensure that all edges are firmly attached.

The screens you choose should be made of durable materials that can withstand the elements. The best option is to use fiberglass screening, which provides the most protection while allowing airflow through the garage. In addition to keeping flies out, this will help keep the garage cool during hot summer days.

Store Food Properly

Another important step in keeping flies out of your garage is properly storing food. Flies are attracted to any food, so ensure that all edibles are kept in airtight containers and stored away from the garage door or windows. These containers should also be cleaned regularly to prevent any buildup of residue or food debris that might attract flies.

It’s also a good idea to keep the area around your garbage can clean and free of food scraps. If you have an outdoor garbage bin, ensure it is covered at all times and that the lid is securely closed when not in use.

Utilize Traps, Repellents, and Zappers

If you notice that you still have trouble with flies in your garage, several products are available to help keep them away.

A fly trap for a garage can be set up to attract fly repellent for the garage, while insect repellents can help prevent them from entering the area in the first place. If you want a more hands-on approach, you can also invest in an electric zapper that will kill any flies that come close. All these options effectively limit your fly population without resorting to chemical sprays and foggers.

For those looking for an even more natural approach, utilize items like cloves and bay leaves, which act as deterrents to pests. Simply place them around the edges of your garage or near cracks and windowsills to repel any pesky flies trying to get in. Alternatively, hanging up a fly swatter can help keep them away and ensure they don’t return.

Removing Standing Water Sources

Flies are drawn to standing water sources, so check your garage for any puddles or other damp areas that could attract them.

Remove any standing water and thoroughly dry the area before covering it with a tarp or plastic sheeting. This will help keep the flies at bay, eliminating their water source. You can also use products like mosquito dunks to prevent larvae from forming in any remaining water.

The best way to prevent standing water from collecting in your garage is to keep it clean and dry. Make sure the flooring is sloped so that any liquid runs out of the area quickly, and inspect the roofing regularly for signs of leaks or other damage.

Install Screens on Windows and Doors

By eliminating standing water sources, you can help ensure that flies will have fewer places to lay their eggs and breed, helping you get rid of them for good.

Bring in a Professional Exterminator

If all else fails, you can always call an exterminator to eliminate any persistent fly infestations. An exterminator can identify the problem’s source and devise a plan to effectively eliminate the pests from your garage. They may also suggest other prevention methods to help you avoid them in the future.

No matter what your fly problem is, following these steps can help you get rid of them and enjoy a fly-free garage. With proper prevention and maintenance, you can ensure that your garage stays clean and comfortable for years to come.
