Here's some more info on our lovely little yellow flies.
The worst time of year is from May to mid June.
They are attracted by dark colors, so remember this when dressing. Wear long sleeve shirt and pants. (GREAT, just what you what to do in our Florida heat.)
Deet is an effective repellent. (Deep Woods Off contains a high % of Deet).
Placing traps under trees helps to keep the populations down.
Yellow Fly Trap
This trapping device is used to reduce the number of yellow flies in the vicinity of a fly breeding area.
Below is a list of materials to use and instructions for constructing the yellow fly trap.
Materials
20" inflatable beach ball (available at
WalMart, Kmart etc.)
10"of ¾ inch PVC or 10" of 1" x 2" wood strip
Glossy black spray paint
String
Glue
Construction
1. Inflate the beach ball.
2. Assemble the inverted L-shaped stand using PVC or wood strips.
(The upright portion of the stand is 6" high with 2 " inserted into the ground. The remaining 2" serves as the right-angled support. The ball may also be hung from a tree, but beneath the canopy.)
3. Paint the ball glossy black and allow the paint to completely dry.
4. Tie the string to the inflation tube on the ball and suspend it from the angled support or tree branch.
5. Snip the corner from the plastic glue bag and squeeze the contents on the top of the ball.
6. Wearing disposable plastic gloves, or using a paintbrush, spread the glue evenly over the ball. (Avoid skin contact. Use mineral spirits to remove any glue that inadvertently comes in contact with the skin.)
Trap Location
The glue ball should be located underneath the tree canopy to take advantage of the yellow flies' preference for shade. Balls hung in the open will not collect as effectively as balls in the shade.
Trap Timing
Yellow flies emerge early in May and are gone by mid-June. Trapping should be done in this time period. Once the nuisance has decreased, the trap should be removed. You may do this by puncturing the ball with a sharp object, then carefully, slide the ball into a plastic garbage bag. Dispose of the bag as you would normally with any household waste.
Keep in mind
When a food source (you) is nearby, the flies will go for the food not the decoy. Avoid going outdoors without repellants or appropriate clothing.
Remember....if you put out traps, put them AWAY from where you wish to eat or sit. Kinda like when folks put out bug zappers right by the picnic table, it DRAWS the bugs to the zappers. Better to put them as far away as possible.
Hope this helps.
