TechNotes Oct. 2 - Spiders, Soil Temperatures

TechNotes are provided by Syngenta GreenCast.

Spiders

Spider populations seem to peak at this time of the year. Spiders are desirable in the landscape since they feed on many insects including pests. The Funnel or Sheet web spiders produce large, flat, sheet-like webs across the turf, or over the branches of shrubs like the yews and junipers. These webs are quite evident when covered with the morning dew.  

Although there are several insecticides labeled for spider control, control is generally not recommended.
