The best methods to deter unwanted guests is to understand the foe before you take the appropriate action.l believe if you think nature then nature will work for you,so forget about all these man made repellents and look closely at what nature has,which is all free and does work for what you want to achieve.
L personally love the wasp and will never harm them ,since they are a gardeners best friend in fighting a war against the pests that destroys the plants.
The wasp is a very territorial insect and will not tolerate any other nesting wasps in the near vicinity.lt only takes one look from the wasp, to see if there is another nest and they will flee elsewhere,they just can’t be bothered with the hassle from a neighbour from hell.
This is why l will mention on how to make your own wasp nest for the sole purpose of deterrent only.lf you want to deter the troublesome insects that will burden your day to day life while having a social outdoors meal with your acquaintances.This should keep the wasps away,without any of the efforts of flapping your arms,shouting out.”Way Hay” all the time
Here is what to do
1/Get yourself loads of newspaper and make a tight bundle out of it,about the size of a football will do,so it will be noticeable.Make sure the bundle is almost the same and color of a real wasp nest,by making sure the grey newspaper shows more on the exterior
2/Tape the bundle together with grey duck tape,if you can get it
3/Use a coat hanger to hang it,by taping the base of the coat hanger,or you can tie it
4/Hang the bundle up where the wasps are and within a few days you will find the wasps will have moved on.
L read this in one of my gardening books years back,because of the wasp nest l had in my shed l wanted to get rid of,but not to harm them.The next few days they were gone,but they left a half finished wasp nest behind
