Wasp repellant. Fill a plastic bag with water, drop a penny into it and hang it above an entrance/patio door and it will prevent the yellow jacket wasps from entering your house and will also help keep them away from your patios. It tricks them into thinking it is another nest so they avoid that area.
The best wasp/yellowjacket repellant for summer picnics: 2 ounces of mint extract. 2 ounces peppermint extract. 10 ounces rubbing alcohol. Pour ingredients into spray bottle and label. Spray down picnic area and play area. The mint is neurotoxic to bees and wasps. Somehow they know to stay away, but if you spray it on them directly it can also kill them.
Your mom may have told you to leave the insects alone, and they wouldn't bother you, but she might need to make an exception for yellow jackets. Members of the Vespidae family, these aerial and ground nesters usually stick to preying on other insects
