Head Lice Medication Available By Prescription

louse nit and louse

Back in 2011, the US Food and Drug Administration approved a new product called Natroba Topical Suspension to treat head lice in both children (4 years of age and older) and adults.

 Take a look at this article Head Lice Biology and Control in School-Age Children for current treatment guidelines for parents and schools.

The active ingredient in Natroba is spinosad a relatively new type of natural, organic insecticide that has been used in commercial agriculture and home gardens for several years. Spinosad is derived through a fermentation process using a specific microbe that was originally isolated from soil. See Using Spinosad in Home Gardens for more information. Natroba is currently available only by prescription for head lice control.

Over-the-counter medications containing permethrin and pyrethrum are still effective against the majority of louse populations but there is some evidence that insecticide resistance to these compounds is increasing. Where resistance to permethrin and/or pyrethrum is suspected spinosad-based treatments may be a viable alternative. No matter which pediculicide (louse medication/insecticide) is used however, proper combing with a fine-tined metal comb is still critically important (see Selection and Use of Lice Combs).

What are these BIG black ants in my house?

carpenter ant In early spring or late winter people often encounter these large black ants in homes. These big ants are different than the more common small, brown "nuisance ants" that plague kitchens. The big ants are called carpenter ants ( Camponotus spp .) and unlike their smaller cousins, nest above ground in cavities. Nest building and cavity expansion by these large, powerful ants can cause damage if nests occur in our homes. Most of the ants you find in homes are small, less than 1/4", and brown. There are several species of small brown ants that can nest in our home's walls or nearby soil and enter homes in search of food and water (see House Ants for identification and control). Nuisance ants are just that, a nuisance. They won't damage your home and pose no health threat of any kind.  There's another ant, however, that occasionally is found in homes that is much bigger (1/4"-5/8"), darker in color, nests in the walls, floors and c...

a thrips next to a leaf vein Have you every felt a sharp pinch while outside during summer only to find a tiny, yellow or black, sliver-like bug when you investigate the bite? These bites are from a tiny insect called a thrips (the name is always plural; one thrips, many thrips). Thrips normally feed on plants with very sharp, knife-like mouthparts but some are predators of other small insects or mites. If they happen to land on us they can bite causing a sharp, stabbing pain. The bites are annoying but completely harmless and are more common in mid- to late summer. Unfortunately, insect repellents don't work against thrips. Continue reading to discover ways to avoid thrips bites at our 'Bugs website . drawing showing feathery wings Thrips can be important plant pests where they damage leaves and in some cases even infect plants with a virus. Greenhouse growers in particular often treat their crops with insecticide to prevent thrips damage. ___________ ...

More Mysterious Bites at Night - After Moving Into New House

The question below represents a number of similar questions we've gotten about "bites" that mysteriously appear in the morning. In this case, the bites started shortly after moving into a newly built home.  Question: What's Causing the Itchy "Bites" - After Moving Into New House? itchy "bites" "We recently built a new home from the ground up. The process took a little over a year but we finally moved in this past October (2009). Not long after we moved (maybe a month?) I started to experience mysterious bites mostly along my thigh area down my leg to my ankle or foot (see photo). These were happening at some point in the night and every night because I am certain they were not there the previous day.  We immediately thought bed bugs since our mattress was stored in a garage during the build, wrapped in fabric but not plastic. We instantly got rid of the mattress, thoroughly cleaned the entire bedroom and home, then continued to sleep on ...
