A person suffering from heat exhaustion will feel hot - cool them off as rapidly as possible and summon help. Fire ant stings are common. Grabbing tree trunks with bare hands to catch one's balance can elicit a bite from orange crab spiders or scorpion stings. Wasps nest on the underside of leaves in the understory, but they have very small colonies and are easily escaped by running through shrubs for a short distance. There are many plastic and metal pipes in the forest that are used as plot markers, and these are favored retreat sites for tarantulas.
Giant centipedes are relatively rare.
They are no more toxic than a normal bee, but they are much more aggressive in defending their colonies. They also divide colonies and occupy new nest sites more frequently than normal bees. There will be traps near the El Verde Research Areas and the Bisley Watersheds that contain an attractant. These traps are very attractive to bees looking for a nest site and should reduce the incidence of new nests in our main LTER research areas. The traps are checked every two weeks, and the hives destroyed.
