[11] [12] In warm climates, and especially the tropics, eggs may be laid 6 inches (15 cm) or more down the hair shaft. [13]
The presence of nits alone, however, is not an accurate indicator of an active head louse infestation. Generally, white nits are empty egg casings, while brown nits may still contain viable louse larva. One way of determining the nit is to squeeze it between two fingernails; it gives a characteristic snapping pop sound as the egg bursts.

Adult non-biting gnats do not damage plants but are considered a nuisance. Usually, larvae do not cause serious plant damage, but when present in large numbers can stunt the plant growth and damage its roots. [6] To prevent gnats from spreading, measures have to be taken to target immature stages of development of the species.
