@ITDept For the ones inside, vacuum all of them up first. Then for preventing more, sprinkle diatomaceous earth on the inside of your house near cracks or wherever you think they might be getting in. Use a small spray bottle (about 8-12oz) and fill with water and then add 20 drops wintergreen or peppermint essential oil. Shake it up and spray on the outside of the house all along possible entrances. I personally wouldn't bother the ones outside because if you have a garden, they're useful by eating aphids. But if you want to repel them from the yard, plant some lemongrass, mums, peppermint, lavender, or catnip. Hope this helps! π
