Indeed.
With donkeys.
Using fly spray on Sugar and Spice has been an interesting process, but halelujah, I think we've won the battle.
Wait, I think I'm mixing metaphors. Oh well. Be patient.
When fly season began, it seemed clear they had never been sprayed. If I so much as appeared with the bottle in my hand, they'd hightail it outta Dodge. So the step process began:
1. Entice everyone into the barn with a "treat" (actually a supplement but they gobble it up).
Spray Luigi and Gabs (who have never been a problem for the past 8 years). Put a halter on S&S with leadline. One person holds the donk while the other sprays. Release the beasts.
After a couple of weeks --
2. Repeat Step 1, omitting the halter. Spray Luigi and Gabs. One person throws the leadline over Sugar/Spice holding securely and the other sprays. Release the beasts.
After a few days --
3. Repeat Step 2, omitting the leadline. One person puts a hand on Sugar/Spice's back or neck to steady them while the other sprays.
It was critical to always spray Luigi and Gabariella first to show S&S they didn't die from the procedure and, in fact, didn't pay much attention. Release the beasts.
After a few days --
4. Repeat Step 3 omitting a person. The procedure requires only one person .Spray everyone in the correct order. Release the beasts.
After a few days --
Spray Luigi and Gabs in the donkey yard. Next spray Sugar (just a wee bit of verbal reassurance needed. Spray Spice with extra verbal reassurance and hand pressure.
Piece of cake!
The beasts (in order of cooperative attitude):
Luigi
Gabariella
Sugar
Spice
Proud as punch of my two little girls!
