Benefits of technology

The present invention provides a way to prevent mosquitoes from breeding in septic tanks and other water / liquid tanks. It does this by using existing waste gas and air vents and reducing exposed areas of still water used by mosquitoes for breeding. The invention also prevents entry of particulate debris, rain or snow and resultant septic tank overflows. The invention is a mosquito screen attachment that is easy to install and prevents rainfall from entering and clogging the systems. The screen is made of a rigid PVC material and can be attached to the vent pipe using PVC cement or metal screening such as aluminum or copper. The screen has screened open faces that help keep particulate debris, rain or snow from accumulating to clog the screened openings. The invention is effective and affordable.

Problems solved by technology

However, they allow rain to penetrate into the septic tank which can cause septic tank overflows.

Embodiment Construction

[0023]FIG. 1 shows the prior art situation with a vent pipe 1 having an open end through which mosquitoes can enter and leave at will.

[0024]FIG. 1A shows another prior art vent pipe 1a having a screened horizontally oriented top open end through which debris, rain and snow can enter and clog the septic tank or other waste disposal structure within the ground.

[0025]FIG. 2 shows the vent pipe screen attachment 2 as a pipe T joint with horizontal section 6 and downpipe 4. Note that downpipe 4 is attached to the open end of vent pipe 1. Circular screen sections 8 are adhesively attached to the open ends of horizontal section 6 by using adhesive in the edge ring area 10.

[0026]FIG. 3 shows the vent pipe screen attachment 20 as a pipe having a horizontally oriented L-shaped joint with two horizontal sections 26 and downpipe 24, which is attached to the open end of the vent pipe 21. Circular screen sections 28 are adhesively attached to the open ends of horizontal section 26 by using adhesi...

Abstract

A mosquito screen attachment denies access to mosquitoes from entering a vent pipe connected to a subterranean septic or other fluid filled tank. It includes a pipe joint section with mosquito screen pre-attached to the one or more vertical open faces of the horizontal portion. The lower opening on the vertical downpipe is simply attached atop the open vent pipe. Preferably the pipe joint is made of PVC which is also the typical material of the vent pipe. A rigid PVC mosquito screening is used, which is bonded or sealed to the edges of the one or more exposed holes of the pipe joint section. A robust material as opposed to a softer fabric screen is preferable to keep out bats or the beaks of birds attracted to hovering mosquitoes near the openings. The vertical orientation of the two vent holes helps keep debris from accumulating to clog the screened openings.

Description

RELATED APPLICATIONS[0001]This application is based upon provisional application serial No. 61 / 573,843 filed Sep. 13, 2011 and claims benefit and priority therefrom under 35 U.S.C. §119(e), which application is incorporated by reference herein.FIELD OF THE INVENTION[0002]The present invention relates to mosquito control.BACKGROUND OF THE INVENTION[0003]Septic systems of buildings are vented to permit accumulated gasses to escape. Carbon dioxide and water vapor constitute some of the escaping gasses. However, mosquitoes are attracted to water vapor, as is commonly known, and to carbon dioxide, as noted in Pike; Jason, “Mosquito Host Attractants”, Colorado State University Entomology course, 2000. Methane is also present in septic systems.[0004]It is well known that mosquitoes seek out still stagnant water to breed. In certain seasons the female is attracted to water vapor and carbon dioxide while seeking a hospitable place to lay eggs. Acting as a lure, septic system vent pipes creat...
