Hi I found a few solutions to this recent problem we had also with bees urinating on and around our home boundaries, including the front hedge,
we tried numerous techniques, we found this strategy to work 99.9% of the time. Follow these simple instructions and I guarantee this will eradicate your problems.
(STEP 1) Find a suitable location to site the deterrent.
(STEP 2) Go to your nearest hardware store and collect a piece of 3”x2” hard wood typically oak or maple wood and cut to approximately 3 feet long.
(STEP 3) Place the piece of hardwood in a jar of white vinegar at one end and allow to soak into the material for at least 72 hours before
proceeding onto the next step.
(STEP 4) Collect some self adhesive foil tape and wrap around the opposite end of the wood using a tape measure exactly 4” down from the end.
(STEP 5) Set up a small camp fire in a safe zone at 6:45 pm on a Wednesday, preferably in autumn. Place the wood soaked in vinegar into the roaring flames of the camp fire and hold the foiled end with your hand until this has completely disintegrated into ashes that are approximately 3.3mm x 2.7mm and in the parallelogram shape.
(STEP 6) Place these ashes of the above sizes into a cup of water and shake vigorously until the colour changes to a dark grey.
(STEP 7) Place this liquid into the freezer for at least 4 days then
take out and place into direct sunlight at 9pm.
(STEP 8) This is the last step.
(STEP 9) Place on a microwavable plate and heat until golden brown
then allow to cool for approximately 3 hours then take over to the designated suspect area and walk past and sprinkle the solution on the property 2 doors down onto the left side gate post and then inform the neighbour opposite about the solution and it’s purpose.
THIS TECHNIQUE REALLY WORKS 99.9% OF THE TIME HOPE THIS WORKS AS GOOD FOR YOU AS IT DID FOR ME
