Deer flies bite both humans and animals, and they draw blood by piercing and sucking it from its victim for several minutes. The various species of deer flies tend to be active from early spring to late fall. Oftentimes, these flies are found in large swarms near bodies of water. To eliminate deer flies and the discomfort they bring, make a rolling trap with the guide below.
Step 1 - Make a Pot Holder
Obtain some wooden planks that can stretch across the hood of your car or front of your lawnmower. Then, mount four to seven four-foot rods into the wood, spacing them equally apart. Allow enough space between the pots to give them free rotation without letting them bump into each other.
Step 2 - Wrap the Pots
Use some bright wrapping paper to wrap the nursery pots. Deer flies are attracted to bright colors, so this will coax them to your trap.
Step 3 - Coat the Pots
Next, spray some insect-trap coating all around the pots. This coating will capture the flies once they draw near to the bright pots.
Step 4 - Mount the Trap
Place your rolling trap across the hood of your vehicle or across the front of your lawnmower. Use some heavy stones or other weights to keep the trap securely placed at the base.
Step 5 - Drive Slowly
For the traps to be effective, they must not only rotate but also be in motion. Deer flies prefer to fly out and attack their prey rather than wait to be attacked. Drive around your yard several times, slowly. The traps will capture large numbers of deer flies. Do this during the day, especially in the mornings, for the best results.
Step 6 - Take Further Preventative Care
While the above method should decrease your deer-fly population, there are a few other things you can do to lessen their numbers.
Construct Shaded Areas
Increase the shaded areas in your garden by planting fast-growing trees or constructing garden umbrellas or canopies, as these pests don’t like shade. Try using homemade fly traps in these shaded areas to get rid of even more of them.
In addition, limit the presence of water bodies and swampy areas in or nearby your home. The larvae hatch in high populations in water bodies, as well as wet soils.
