Few insecticides are effective for spider mites and many even aggravate problems. Furthermore, strains of spider mites resistant to pesticides frequently develop, making control difficult. Because most miticides do not affect eggs, a repeat application at an approximately 10 to 14 days interval is usually needed for control. Since an egg can develop into a mature spider mite able to lay eggs of its own in as little as 9 days, more frequent application may be required in hot, dry conditions.
