Are Spider Mites Killed By Heat?

The study investigates the effects of hot air on the survival and reproduction of the European spider mite species, Tetranychus ludeni Zacher, an important invasive pest in horticulture. Spider mites thrive in warm and dry conditions, which are ideal for indoor plants and outdoors in summer and winter. They prefer dusty plants, making it helpful to spray outdoor plants with a water hose.

Spider mites are vulnerable to being overused by broad-spectrum pesticides, which can lead to large infestations. To eradicate spider mites, one can use one hot air treatment at 57°C for six hours or two treatments at 51°C for three hours at a 10-day interval to kill all eggs in the first treatment and those laid by survived adults in the second.

Spider mites are tiny sap-sucking plant pests that attack the underside of leaves and suck the vigor from plants. Overnight freezing temperatures are only effective at killing spider mites when it occurs early in the season, before the mites have developed. To combat spider mites, bring down the temperature in grow spaces, such as air conditioning or venting greenhouses.

Spider mites are highly successful at surviving unfavourable environmental conditions, such as winter temperatures and periods of heat or drought. At temperatures over 40ºC (104ºF), they suffer from heat stress and may die, especially if these climatic conditions remain for a prolonged period. Control of spider mites by P. persimilis may become less efficient under extreme heat waves, partly because spider mites are tiny insects that suck the life out of plants. Both warm and cool season spider mites do best in the absence of rain when humidity is low, but extremely high temperatures, especially those above 33°C, can be lethal to spider mites.

In conclusion, the study suggests that using hot air treatments at 57°C for six hours or two treatments at 51°C for three hours at a 10-day interval can effectively eradicate spider mites from indoor plants.
