PLACING the units in the parking area as at the Hallandalo, Hullandale, Fla., is very effective.

only one or two insects in the Mercury Vapor light traps. The wattage of the black light trap was 15 watts in one trap, and 60 watts in the other. Therefore, by this comparison, it can be seen that the black light traps were much more effective.

It is the purpose of the above information to show that black light tubes, even at far 165s wattage, will draw insects away from other commercial light sources.

It has often been asked how far will these lights attract insects, and what makes them react to the light. Actually, at this time, there is no scientifically accepted answer to either question. It is known that insects marked by dye for identification purposes have been released from as much as three miles from a black light trap, back of a heavy woods through which the black light lamps were not visible to the naked eye; yet, these insects have been taken from the traps the following day. It is aISO reasonably well established that the influence of light on many insects is so strong that they will invariably break their normal routine and move to the light source as soon as they come into the area where the light is exposed.

Another Test

A further indication of the attraction which black light has for insects can be gotten from the results obtained from a test conducted at Clear Lake, California. The unit used in this test had the black light as the lure, but used a suction fan in place of the electric grid. It has been found that the electric grid, such as the one used on the Insectocutor is even more effective than the suction fan. This fan sucked in all the insects that came near the black light and deposited them into a net that was attached. The following facts were given by the U. S. Department of Agriculture: uEight-five pounds of Clear Lake gnats attracted by an electric lamp, were caught in a single night in a suction-type trap. Each pound contained about one million insects. House and stable fiies attracted to a bait in an electric grid box trap have been destroyed at a rate of 100,000 a day?

Installed in Drive-Ins

A number of Insectocutors have already been installed in outdoor theatres, and the reports on them haue been very satisfactory. Charles Goldfine, operator of the South City Drive-In, Philae delphia, Pa., has been using Insectocutors for three seasons, and he reports that, "they have helped considerably to relieve us of our night-flying insect problem. We have found them particularly satisfactory in controlling insects around the

snack bar, restrooms and ticket office."

lnsectocutors have also been installed in drive-ins in the southern portions of the United States where there is a particularly bad bug problem. This area of the country attracts moths, some of

them with wing spreads of as much as four and one-half inches, which fiy across the screen during the projection period. To combat this, units are mounted on each side of the screen and slightly back of it, to the side. The insects will then be drawn to the Insectocutor, but they will not fall in front of the screen. The ticket booth area can be cleared of pesty insects by placing Insectocutors slightly away from the booth, thus drawing the bugs away and killing them.

Construction Features

Although the black light tube used in the Insectocutor does give off some visible light, it is so slight that there have been no reports of a complaint by patrons.

An possible danger which might result from a theatre patron accidentally touchthe electric grid has been avoided by using a step-up transformer which r*duces the current to a maximum of 10 milliamperes, a charge said to be so low that humans and animals cannot be harmed or affected in any way. However, this charge is still strong enough to be deadly to all dying insects on contact.

Another feature of this device which makes its use in drive-ins practical is that it requires no maintenance or supervision. The panels are constructed of high rust-resisting steel, and it is claimed that the transformer and grid will not burn out in high humidity, heavy dew, or a driving rain. This also means that the Insectocutor will work at all times, during any sort of weather. It: construction involves no moving parts, and thus it may render many more sea sons of efficient operation than its estimated 20 years of life.


The black light tubes in the Insectocutor will draw insects from considerable distances, and a rather small number of units will do an adequate job in a drive-in. They may be mounted on poles, fences, or walls, and should be placed from about eight to 10 feet above the ground. While its effectiveness is not lessened against other insects if placed higher, its effliciency against the ordinarily low-Hying mosquito is lessened with each additional foot in height over 10.

Some of the other advantages claimed for Insectocutors are as follows:

1. Reduces the labor requirements for

the control of night-flying insects.

2. Eliminates all, or part of the need for insecticidal mists and fog producing sprays.

3. Eliminates weather hazards which areiencountered during the present control methods.

4. Experiments indicate that black light traps are effective during rainy weather when it is difficult to use dusts and sprays.

5. Eliminate: or reduces possible harm or injury to individuals in the control of insects.

6. The unit is long-lasting, requires little maintenance, and works only when needed.

The Inscctocutors are easy to handle being 24 by 28 inches in size. with a shipping weight of 40 pounds. The black light tubes are estimated to give over 3000 hours of use.
