Beginner Gardening: Help! Foreign Spiders, 1 by ninachopper

I have recently purchased two Tacca chantrieri Black Bat Flower bulbs. They were shipped to New Jersey from Thailand. Upon opening them I discovered a small spider (harmless looking but... you never know!) I got rid of it and took out the bulbs getting ready to plant. Then I found two more spiders that looked the same only much, much smaller. I do not want to introduce any foreign species to my yard, but I am worried about more babies. Is there something I can do to the bulbs before planting without harming the plants to get rid of any eggs, nests, or babies?
Thanks for any advice!!
