unless defined otherwise , technical and scientific terms as used herein have the same meaning as commonly understood by one of ordinary skill in the art . one skilled in the art will recognize many methods can be used in the practice of the present disclosure . indeed , the present disclosure is in no way limited to the methods and materials described . any references cited herein are incorporated by reference in their entireties . for purposes of the present disclosure , the following terms are defined below . as used herein , “ a reduction ” of a population of arthropods such as an insect population or arachnid population in an environment having phpg means that the level is reduced relative to the numbers of organisms of a population in an environment lacking phpg . in some aspects , a reduction may occur due to the death or incapacitation of an arthropod population or due to the exit of members of the population from the phpg containing environment . as used herein , the term “ at least a partial reduction ” of a population of arthropods such as an insect population or arachnid population in an environment having phpg means that the level is reduced by at least 25 % relative to the numbers of organisms of a population in an environment lacking phpg . also as used herein , it is understood that in environments having multiple populations of arthropods , each population may be “ partially reduced ” independently . as used herein , the term “ a substantial reduction ” of a population of arthropods such as an insect population or arachnid population in an environment having phpg means that the level is reduced by at least 75 % relative to the numbers of organisms of a population in an environment lacking phpg . also as used herein , it is understood that in environments having multiple populations of arthropods , each population may be “ substantially reduced ” independently . as used herein , the term “ an effective elimination ” of a population of arthropods such as an insect population or arachnid population in an environment having phpg means that the level is reduced by greater than 95 % relative to the numbers of organisms of a population in an environment lacking phpg . also as used herein , it is understood that in environments having multiple populations of arthropods , each population may be “ effectively eliminated ” independently . an effective amount of phpg is preferably capable of providing at least a partial reduction , more preferably a substantial reduction , or most preferably effective elimination of an arthropod population . as used herein , the terms “ suppress ,” “ repress ,” and “ downregulate ” when referring to a population of arthropods used equivalently herein and mean that the levels of a population of arthropods are reduced relative to the number of arthropods in a population that would occur in the absence of phpg under similar or identical conditions . as used herein , the terms “ control ,” “ controls ,” or “ controlling ” a population of arthropods by providing phpg to the arthropod for a period of time refers to either the killing of the arthropod , induction of a behavioral change in the arthropod , or both , that results in reduction of the population of the arthropod in the phpg environment relative to an untreated environment . as provided in detail below , different arthropod populations are controlled at different levels of phpg and may require different periods of exposure to the phpg environment to accomplish desired levels of reduction . as used herein , the singular form “ a ,” “ an ” and “ the ” include plural references unless the context clearly dictates otherwise . for example , the term “ an arthropod ” or “ at least one arthropod ” may include a plurality of arthropods , including mixtures thereof . also as used herein , an arthropod includes and provides for a population of arthropods . as used herein , a population of arthropods may further include a mixed population of arthropods . the present disclosure provides for an includes method for controlling an arthropod by providing phpg to the arthropod for a period of time . an arthropod may be controlled in a variety of ways including by killing the arthropod at one or more stages of development or as an adult . in certain aspects , providing phpg to an environment leads to the death of the arthropod after a period of time . in an aspect , providing phpg gas provides for the death of a nymph stage of an arthropod . in an aspect , phpg gas causes the death of an arthropod egg such that larvae never hatch . in an aspect , phpg acts on adult stages of an arthropod . in some aspects , providing phpg is an effective arthropodicide against all developmental stages of an arthropod species . as provided below , both the length of time necessary to kill the arthropod and the amount of phgp necessary to kill the arthropod may vary depending on the species of the arthropod . the present disclosure also includes and provides for methods of control which disrupt the behavior of the arthropod . in some aspects , the methods of control provide for both the disruption of arthropod behavior and provide arthropodicidal effects . in some aspects , after initial exposure to a concentration of phpg , the arthropod ceases all activity and becomes immobile and dormant . in other aspects , exposure to a concentration of phpg leads to enhanced activity of the arthropod . in certain aspects , the activity of flying arthropods greatly increases and can be characterized by high agitation and frantic activity . in aspects according to the present disclosure , control of an arthropod after exposure to phpg includes disruption of normal mating behavior . other behavioral changes observed in arthropods exposed to phpg containing environments includes disorientation . in an aspect , the present methods included inducing disorientation in an arthropod species . in some aspects , disorientation leads to a loss of feeding behavior . in other aspects , disorientation leads to a loss of mating behavior . in certain aspects according to the present disclosure , changes in behavior caused by exposure to phpg may also be accompanied by physical signs of distress of the arthropod . in some aspects , physical signs of distress include regurgitation of recent meals . in another aspect , the arthropod may prematurely lay eggs . in certain aspects , the prematurely laid eggs may be fertilized eggs . in other aspects , the prematurely laid eggs may be un - fertilized . in aspects according the present disclosure , exposure to phpg gas results in the death of the prematurely laid eggs . also provided and included in the present disclosure are methods of controlling larval forms of an arthropod . in certain aspects , providing a phpg leads to the premature hatching of an immature egg . in an aspect , methods to control an arthropod lead to the death of larval forms of an arthropod . in some aspects , larval forms are more sensitive to exposure to phpg than adult or nymph forms . thus , in some aspects lower levels of phpg may control immature forms of arthropods where the adult form is significantly less affected . in some aspects , phpg is provided to a larval form to inhibit the metamorphosis of the larva . in an aspect , phpg may be provided at sufficient levels to act as a larvacide . the present disclosure further provides for and includes methods of killing nymph forms of arthropods . for many arthropods , exposure to phpg leads to significant changes in behavior and phpg acts as a very strong repellent . in some aspects , exposure to phpg leads arthropods to search for an exit from the phpg containing environment . in an aspect where the arthropod is unable to escape , the arthropod locates to a source of fresh ( non - phpg containing ) air and attempts to survive . in household or non - experimental setting , such arthropods would exit the domicile or environment . similarly , arthropods are repelled from entering environments that have even very low concentrations of phpg . thus the present disclosure provides for methods of controlling an arthropod by providing a phpg containing environment and repelling insects , thereby blocking their entry . in aspects according to the present disclosure , phpg levels may be provided in excess over the amount necessary to kill a arthropod species . in such aspects , the control methods of the present disclosure are effective against almost every arthropod tested including examples from multiple phylogenetic orders and classes . the few arthropods that appear to be resistant to phpg levels up to 0 . 6 ppm for 24 hours included adult cockroaches and tarantula spiders . phpg is lethal to most species . determining whether any specific species of arthropod is resistant or susceptible can be easily performed using the methods described below and known to one of skill in the art . certain arthropods are more susceptible to the methods of the present disclosure . not to be limited by theory , flying insects , such as diptera , are generally most susceptible due to high activity and rapid pumping of air containing hydrogen peroxide through their tracheal tubes . accordingly , methods to control flying insects require lower levels of phpg gas and are particularly suited to methods of control wherein the arthropod is repelled from the phpg containing environment . with respect to arachnids , those species having ‘ book lungs ’ are generally more susceptible than the tracheal tube systems of crawling insects . the present disclosure provides for and includes methods of controlling book lung containing arthropods including arachnids and scorpions . in some aspects , larger arthropods appear to be more resistant to the killing effects of a phpg environment . not to be limited by theory , this may be the result of an increased diffusion distance to more sensitive portions of the arthropod body . alternatively , the larger arthropod may be able to survive longer on stored oxygen once the tracheal system is closed off . in aspects according the present disclosure , resistance may be overcome by either increasing the length of time of the exposure , increasing the concentration of phpg gas in the environment , or both . it is understood that using the methods of the present disclosure and the knowledge of one of ordinary skill in the art , the particular effect on an arthropod may be readily determined . further the level of phpg necessary to kill , inhibit , or repel a given arthropod as well as the length of time necessary to kill , inhibit , or repel may be readily determined using the disclosed methods and knowledge known in the art . without being limiting , phpg may be produced by a device for producing non - hydrated phpg having an enclosure , an air distribution mechanism providing an airflow , a thin air - permeable substrate structure having a catalyst on its surface , and a source of light , where the airflow is through the air - permeable substrate structure and the device produces phpg and directs it out of the enclosure when in operation . in some aspects , the source of light is a source of ultraviolet light . in some aspects , the airflow comprises an angle of incidence to the substrate structure that is greater than 45 degrees . in one aspect , the angle of incidence is 90 degrees . in another aspect , the airflow comprises air that has a humidity of at least 5 %. in one

s instructions . the polytron displays a digital reading when air is drawn through the mesh sensor . most commonly , draeger tubes are used after clipping on both ends and placement in a accuro ™ pump . per manufacturer instructions , the tubes are pumped 100 times and the level of phpg determined by observing the color change in the crystals . the pac iii has proved to be generally less effective in measuring very low levels of phpg . the effects of purified hydrogen peroxide gas ( phpg ) on selected arthropod species is performed to determine the efficacy on controlling an arthropod using the indirect dispersion of phpg in a space . in these experiments , the knockdown and mortality rates in mosquitoes , bed bugs , termites , ants , moths , house flies , and spiders is assessed . black wood ants , house flies ( adult and pupae ), large saturniid moths , termites ( soldier and living ), and cellar spiders are obtained from carolina supplies and shipped overnight . all organisms are fed prior to shipping from carolina supplies . bed bugs and mosquitoes are sourced locally due to government shipping restrictions . the test samples are stored in a cabinet at ambient temperature and humidity until use in the study . the samples are labeled and color - coded for easy identification . in certain experiments , specimens of wild caught arthropods are used in the controlled experiments , including for example brazilian cockroaches . all testing is conducted in a sealed , static dissipative pvc chamber , terra universal ( fullerton , calif .) model 3305 - 10f : 59 inches w × 24 inches d × 25 inches h . with additional airlock terra universal model 1680 - 81b 11 . 5 inches w × 10 inches d × 10 . 5 inches h . arthropods are placed inside transfer containers ( pint size paper containers ). the top and bottom diameters of these containers are 3 . 75 and 2 . 87 inches respectively with a height of 3 . 5 inches . all arthropods are released once the airlock is sealed . arthropods are allowed to recover following phpg exposure and observed in 8 oz glass pyrex ® ( tewksbury , mass .) containers with sealed glass lids . three replicates of ten of each arthropod are subjected to phpg . an additional three replicates are subjected to a non phpg producing device and serve as untreated controls . the arthropods are observed for knockdown at 0 . 5 , 1 , 2 , 3 , 4 , 5 , and 15 minutes . mortality counts are taken after 24 hours of phpg exposure . if at 24 hours mortality is less 90 %, additional readings are taken following 48 hours of phpg exposure . the test samples are exposed to the test environment containing phpg until a 90 % knockdown is achieved . the test samples are provided phpg emitted from a phpg producing device in the center of the test chamber . time frames are recorded for each replicate . just prior to treatment the arthropods are transferred into the transfer containers . forty eight hours after treatment , they are removed from the treatment chamber and transferred to recovery containers and covered with screened lids for observation . after treatment , the arthropods are observed for knockdown and mortality at 0 . 5 , 1 , 2 , 3 , 4 , 5 , 15 , 30 minutes and 1 , 2 , 3 , 4 , 5 , 10 , 15 , 24 , and 48 hours . knockdown occurs when an arthropod cannot right itself when placed on its back but is still able to move at least one body part . the arthropods are then transferred from the treatment chamber to recovery containers . another knockdown / mortality observation is made 15 minutes later . if all ten arthropods are recorded as knocked down or deceased during any observation before 15 minutes have elapsed , subsequent observations are not made . mortality counts are made at 24 hours , and 48 hours or sooner ( if applicable ). all dead arthropods are confirmed by probing or agitation to make sure that they are unable to move ( any that show movement visible to the naked eye are recorded as moribund ). arthropods that can crawl or right themselves when placed on their backs are recorded as being alive . after the knockdown counts are complete , the arthropods are maintained in the laboratory at ambient temperature and humidity conditions with a normal 8 : 16 light : dark cycle for 24 hours . additional mortality readings are taken at 48 hours if less than 90 % mortality is recorded at 24 hours . a 48 hour reading depends upon control mortality remaining less than 10 %. temperature and humidity are recorded in the treatment area , and in the laboratory where the arthropods are subsequently held for the duration of the test . the number of dead arthropods per replicate are added together for a total mortality count . abbott &# 39 ; s formula is used to correct for any mortality among the controls . the results are presented in table 1 . in november 2012 , the effects of phpg gas treatment according to the present disclosure was performed on a 1400 sq ft pool house that had not been maintained for years . prior to testing , the primary function was for storage and the very occasional guest . window seals were cracked and therefore air leakage throughout the space was increased . initially there was some mold present on the wall with an “ in window ” air conditioning unit . prior to the initiation of testing , the space itself was cleared out and swept clean . no chemicals or cleaners were used at any time in this space for weeks prior to testing . there was no cleaning or dusting of the exposed rafters , kitchen cabinets , drawers , closets or the hvac system that was not operational for years . a space heater was included to maintain the temperature above 60 degrees ° f . two 14 ″× 12 ″ by 12 ″ phpg generating devices comprising a filters , fan , bulb , and a phpg generating sail ( see , u . s . pat . no . 8 , 168 , 122 , u . s . pat . no . 8 , 685 , 329 , and u . s . patent application no . 61 / 988 , 535 ). two phpg generating devices were placed in the space for an initial cleansing and to establish levels . after 27 hours , 109 arthropods were confirmed dead including crickets , ants , spiders , and house flies . the majority of the kills happened around the outer walls of the space with limited kills in the interior portions of the space . observed concentration of phpg , measured as provided in example 1 , at 27 hours was 0 . 4 ppm . no live insects were observed . the effects of phpg treatment of human lice was observed . after installing a phpg generating device , the child subject reported the end of itching within one hour . all signs of lice were eliminated and lice free within two days of the initiation of treatment . additional observations of the effects of phpg treatment of arthropod species was observed during the development of phpg generating devices for the control of molds , bacteria , and viruses . the results and observations of these species is presented in table 2
the present disclosure relates to methods and devices for controlling arthropods , including insects and arachnids in an environment . the methods generally comprise : generating a near - ideal gas purified hydrogen peroxide gas that is substantially non - hydrated and substantially free of e . g ., ozone , plasma species , and / or organic species ; and directing the gas comprising primarily phpg into the environment such that the phpg acts to control arachnids in the environment . in certain aspects , the arachnids may be totally or partially killed .
