With warmer days ahead, I swear by this trick to getting rid of all the flies, mosquitoes, and bugs

Step 1: Combine Things needed: Mix the shampoo and vinegar in the small basin. Make sure the vinegar and shampoo are well combined by stirring them together.
Olive oil should be added. Add the olive oil little by little to the bowl. A thin coating of oil should form on top of the liquid as it floats to the top.
Deploy the Trap: Put the basin somewhere where you often see a lot of mosquitoes or flies. Any wet spots, such as those near windows or doors, might be a candidate.
The Process:
Because of its powerful and delicious aroma, vinegar attracts flies and mosquitoes and serves as a bait for them. Particularly effective is apple cider vinegar because of its inherent fermenting properties, which these insects find enticing.

Entrapment: Insects that try to settle on the surface of the vinegar will find it simpler to sink thanks to the shampoo in the combination, which lowers the surface tension of the vinegar.
A slippery barrier is formed on top of the mixture by the olive oil. If you put flies or mosquitoes in the trap—particularly via the perforations in the plastic wrap—the oil will suffocate them, limiting their ability to fly away.
Notes:
Use this trap around the house without worrying about hurting your kids or pets. If you’re worried about spillage, however, put it somewhere out of reach.
