Are fungus gnats harmful? Adult fungus gnats don’t damage plants or bite people; their presence is primarily considered a nuisance. Larvae, however, when present in large numbers, can damage roots and stunt plant growth, particularly in seedlings and young plants.
Are wolf spiders dangerous? These spiders are often big and hairy which alarms some people, but they are primarily nuisance pests. Wolf spiders can inject venom if continually provoked. Symptoms of their bites include swelling, mild pain, and itching.
