Pesticides: |
Pesticides are any substance or mixture of substances
intended for preventing, destroying, repelling a pest.
Pesticides can be chemical substances or biological agents
(like a virus or bacteria) applied against pests such as
insects, weeds, mollusks, birds, mammals, fish, that
compete with humans for food, destroy property, spread
disease or are a nuisance. Most pesticides are hazardous
to humans.

| Definition of IGR’s: |
Insect Growth Regulators (IGR’s) are the insect hormones (or their synthetic mimics) that control an insect’s maturation processes and other important functions. IGR’s are sometimes referred to as third-generation insecticides.
The first generation consisted of stomach poisons such as arsenic compounds.
The second generation included the commonly used organo-chlorines, organo-phosphates and carbamates.
The third generation, the IGR’s, are the newest compounds on the scene and there are great hopes for this class of pesticide.
Insects like other animals are regarded as biochemical factories, with each of their various glands producing specific compounds. These compounds function in reproduction, co-ordination of the nervous system, tissue protection and repair, molting and metamorphosis.
The search for less-toxic insecticides has focused on substances such as IGR’s that affect biochemical processes unique to arthropods (insects, arachnids and crustaceans), so that the potential negative effects on humans and other mammals are minimized.

| Definition of Residual sprays: |
Insecticides that provide residual protection continue working after the initial application, maintaining the efficiency of the treatment against the target pest.
An Emulsifiable Concentrate (EC) is a liquid concentrate that when added to water creates a pesticide solution. In most cases, EC is the designation for an emulsifiable insecticide concentrate product. Emulsifiable concentrates usually dry clear and give 28 to 31 days residual.
A microencapsulated (ME) product can give you a longer residual than a conventional liquid concentrate (EC). This type of insecticide is designed to contain microscopic particles of insecticide (invisible to the naked eye) and when applied will actually deposit on surfaces where it is sprayed or applied. These tiny "bubbles" of active ingredient burst when stepped on by or groomed in by the targeted pest.
Wettable powders (WP) are regarded as the best when maximum residual effect is required. WP’s do not dissolve when mixed with water a wettable powder forms a suspension. Effectively, the particles that make up the insecticide float throughout the solution.
The main advantages of wettable powder insecticides: initial knockdown and kill of targeted pests, extended residual effects and (in most cases) odorless. A WP product has a longer residual than micro encapsulated concentrates.
When an emulsifiable concentrate insecticide is mixed and sprayed on a wood surface, much of the active ingredient is absorbed into the wood or evaporates. When a wettable powder solution is sprayed on the same surface, 100% of the active ingredients are left on the surface of the wood. This feature provides a faster knock-down of insects and other pests. This insecticide formulation also gives a 90 day (or better) residual; emulsifiable concentrated products give 28 to 31 days residual.
The main disadvantage of a wettable powder: the finished solution can leave a visible residue on dark surfaces. (Visible residue is not to be confused with staining. Most professional indoor pesticides are water-safe for fabrics)

| Definition of knockdown: |
Knockdown is a term to describe an ‘instant kill’ insecticide of insects generally a pyrethroid or tetramethrin based ingredient. Theses disrupt neural transmissions by interrupting the normal functioning in the transmission of neural impulses.
