Description

Insecticide Tablecloth for Electric Fumigator -

  The present invention relates to a

  insecticide position for electric fumigator More

  In particular, it relates to a

  breuse having a thickness of 1 to 1.25 mm and

  surface area of 5 to 15 cm 2, and containing a

  high concentration of insecticide which is obtained by impregnating a web of a premix composition comprising pyrethroid insecticides, stabilizers, dyes, and other adjuvants

  in an amount of 75 to 300 mg.

  Traditionally, so-called mosquito rollers have been used to exterminate

  mosquitoes, mainly in homes.

  Recently, the classic mosquito roll has been upgraded to a new device called a fumigator

  which consists of the combination of a

  electric heating system and a fumigant

  molded generally referred to as a mosquito

  to be placed on the heater to vaporize insecticidal ingredients that

are contained.

  The particular terminologies and con-

  Basic births relating to what is mentioned above are explained for example in the United Kingdom of Great Britain and Ireland

1,288,138 and 1,587,396.

  Electric fumigators used as electric mosquito exterminators, as well as mosquito rollers and insecticide aerosols are now widely used. However, the presently available slick targets only mosquitoes, as indicated

his common name -

  Finally, in chicken coop areas,

  cattle, from the landfill, swarm

  wind flies that go to a residential area

  It is therefore desirable to apply

  continue to take effective measures to combat a nuisance caused not only by mosquitoes but also by flies and

other vermin.

  After studies to meet this requirement, it has been found that a sufficient amount of active ingredients can be vaporized in the air and maintained at an effective concentration for a long period of time, by heating the

  sheet having the characteristics mentioned above

  sus, at a temperature between 1400 C and 1800 C, which exterminates flying insects, such as flies, mosquitoes and, in addition, crawling insects and other than cockroaches, fleas,

bedbugs and other vermin.
