Deer flies can be a persistent nuisance around outdoor trash cans, but there are several effective strategies to keep them at bay. First, ensure your trash cans have tight-fitting lids to minimize odors that attract these pests. Regularly cleaning the bins with a mixture of vinegar and water can also deter deer flies by eliminating food residues.

Another method is to use natural repellents like essential oils (e.g., eucalyptus or citronella) around the trash area. These scents are unappealing to deer flies. Additionally, placing sticky traps or fly ribbons near the cans can help reduce their population.

For long-term prevention, consider relocating trash cans away from high-traffic areas or shaded spots where deer flies thrive. Combining these tactics will significantly reduce the likelihood of deer flies swarming your outdoor trash cans.
