A Brown Recluse Experiments
by David Stewart
The Brown Recluse Experiment: Seeing how squirting a peppermint-water spray would kill flies in mid-air, I wondered what pure oil would do. So I did an experiment on a brown recluse spider. I captured a live one in a jar and carefully placed one drop of peppermint on one side. The pure peppermint repelled the spider who crowded to the other side to avoid the oil. When I tipped the jar to force the spider to fall into the oil, it merely squirmed and got away, still repelled by the oil, but not apparently harmed. Then I put a drop of water with the oil and tipped the jar so that the spider slid into the water and oil together and, instantly, it shriveled up and died.
Conclusion: The oil alone is an insect repellant. Combined with water, it is an insecticide.
