noun
chicken mite; red poultry mite
Scientific name Dermanyssus gallinae; a common pest in poultry farming.
ワクモは鶏舎でよく見られる吸血性のダニです。
The chicken mite is a blood-sucking mite commonly found in poultry houses.
The origin is uncertain. The kanji 鶏 (chicken) and 蜱 (tick/mite) describe the organism, but the reading わくも does not follow standard on'yomi or kun'yomi patterns and may be a specialized term.
