Wash your body with Fels-Naptha soap. Use the bar soap as you would traditional soap, moving it over your body and then rinsing with clean water. The soap will help to kill any insects on your body and soothe any bug bites.
Keep Fels-Naptha soap away from your eyes. It contains Stoddard solvent, a white spirit which can be highly irritating to the eyes. If you get Fels-Naptha soap in your eyes, rinse promptly with cool water.
Grate a bar of Fels-Naptha soap. Mix 3 tbsp. of the grated soap with 1 gallon of boiling water. Stir the solution and allow it to fully cool. Place the solution in a water bottle and spray it over your garden. The mixture will kill existing insects and keep new insects at bay.
Cut a bar of Fels-Naptha soap into 1-inch pieces. Distribute the pieces throughout your garden, placing them at the bases of plants. The soap will repel insects.
Treat clothing with Fels-Naptha soap. Rub the bar directly onto your clothing prior to laundering it. If any insects exist on your clothing, it will kill them. The soap will also kill any insect eggs that may be present on the clothing.
