๐ฎ๐ง๐ ๐ฎ๐ฌ ๐๐ง๐๐ญ๐ฌ? Fungus gnats are tiny flying insects, usually no more than an eighth of an inch long. At a glance, they look like miniature mosquitoes, but theyโre more annoying than dangerous. While adult gnats donโt bite or harm plants directly, their larvae feed on organic matter and sometimes delicate plant roots in the top layer of soil. That means young seedlings, herbs, and moisture-loving houseplants are most at risk. They thrive in damp, organic-rich soil, especially when containers stay moist for too long, which makes them right at home in many indoor setups. ๐๐๐จ๐ฐ ๐๐จ ๐๐ฉ๐จ๐ญ ๐ ๐
