I kinda figured this would be the best place for this.
Most folks know I live remote, very remote. Water around here is very scarce in any form, folks here have wells. Every year the Mud Daubers have been getting worse, and that can of wasp spray isn't getting any cheaper.
I've taken down the nests over the years only to have them rebuilt in no time. Every time we water here out they come in full force and gather mud at an alarming rate.
I got this recipe off of YouTube and decided I only had a few bucks to lose if it didn't work.
16oz empty spray bottle (Must have a stream nozzle and NOT the spray nozzle.) Almost full of water of course
1\4-1\2 cup of Dawn soap.
20 drops of Peppermint Oil (@ WallyWorld $6 for .5 oz)
When you give them a good hit with the stream from the spray bottle the results are almost instant. Had a few hornets come in and I got the same results, and so far flies aren't immune either.
It doesn't work like the poisonous sprays, but takes a few seconds for the spray to take effect so be patient. Sprayed any nest I could find since the spray gets rid of what is inside as well.
Here I was making rice loads for the 357mag and getting them that way. Those Mud Daubers seemed to be armor plated at times, but this stuff really does the job and it isn't toxic like the canned spray. I made almost 200 rounds of those rice loads, which take a while to do, and this home brewed spray is rather cheap and effective.
A person needs to enjoy the smell of peppermint, just a single spray and it gets fragrant real quick.
