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.
Are centipedes dangerous? Centipedes are generally considered nuisance pests because they do not pose significant health or property threats. However, all house centipedes have poison jaws with which they inject venom into their prey.
Centipedes are easy to spot by their elongated, worm-like body with their many pairs of legs. They can actually have anywhere from 15-177 pairs of legs with one pair per segment, depending on the species. Interestingly, centipedes always have an odd number of pairs of legs.
