Lavender is a safe, natural way to give spiders the boot without exposing your kids to the dangerous chemicals contained in pesticides. It won’t kill the spiders but they don’t like to walk across areas with strong scents including lavender, citrus and peppermint. Since spiders taste with their feet they are thrown off by powerful fragrances and will normally avoid sprayed areas at all costs.
Fill a 16-ounce spray bottle nearly full of warm water. Leave enough room to add lavender oil and dish soap, plus a bit of space so that you can shake it up.
Add between 5 and 7 drops of essential lavender oil to the water in the spray bottle.
Measure 3 to 5 tablespoons of dish soap into the spray bottle to help the oil droplets break up and spread through the water more evenly.
Replace the top on the spray bottle and shake well.
Spray the mixture anywhere spiders are a problem. The lavender will form a barrier and repel the eight-legged intruders. Spray areas such as around windows and doors, at the base of walls and from ceiling to floor in corners.
