Description

Gosh darn red spider mites kill my tomatoes every time. They're less during the rainy season, but as soon as it's dry for a week, they pop up. Brushing webs off and spraying and/or brushing the leaves down helps a bit, but it has to be done regularly. That was with diluted neem soap, I haven't tried fresh neem yet. Next round.
They like beans too. When the infestations get really bad they'll even spread to squash and non-living plant matter (like stakes and the fence)

Description from Wikipedia

Arachnids are a class (Arachnida) of joint-legged invertebrate animals in the subphylum Chelicerata. All arachnids have eight legs, although the front pair of legs in some species has converted to a sensory function, while in other species, different appendages can grow large enough to take on the appearance of extra pairs of legs. The term is derived from the Greek word ἀράχνη (aráchnē), meaning "spider".
