Do-It-Yourself Bed Bug Detector

From December 18, 2009 Science News, by Susan Milius

After trying some 50 arrangements of household objects, researchers have come up with a new, homemade bed bug detector.

Wan-Tien Tsai of Rutgers University worked with Changlu Wang, also at Rutgers, for six months on designing homemade devices that lured bed bugs out into a trap so residents can tell whether a home is infested.  Like many insects that search for blood, bed bugs are attracted to plumes of concentrated carbon dioxide, good clues that an animal filled with liquid dinner is breathing somewhere nearby.  In lab tests, carbon dioxide beat heat and several chemical attractants in drawing the bugs out of hiding.

 The adult house fly is 6 to 7 mm long, with the female usually larger than the male. The abdomen is gray or yellowish with dark midline and irregular dark markings on the sides. The underside of the male is yellowish.

Maggots are the early instar larvae. They are typically creamy whitish in color, cylindrical but tapering toward the head. The head contains one pair of dark hooks. The legless maggot emerges from the egg in warm weather within eight to 20 hours, and immediately feeds on and develops in the material in which the egg was laid.

Killing adult flies may reduce the infestation, but elimination of breeding areas is necessary for good management. Garbage cans and dumpsters should have tight-fitting lids and be cleaned regularly. Dry garbage and trash should be placed in plastic garbage bags and sealed up. All garbage receptacles should be located as far from building entrances as possible.

Please visit our Do-It-Yourself-Store for all the products you will need for these and other insect problems. A good residual to use is Talstar or Max Force bait.

Thank you for reading and I hope it helps.

 After you are done come to my Ants-R-Pests Depot Do It Yourself Pest Store to keep the spiders from jumping on you.

Remember spiders need live insects to feed on to live. They catch the spiders by using webs. They inject their prey with venom through fangs.

When you are moving things indoor look to make sure they are not harboring any spiders or insect prey that will feed the spiders.

Typically spiders will not go on offense to attack a person. They will bite when pressed between shoes, clothes or hats and your skin.

Some great products to use are: CB80-Extra, Demon WP,or Delta Dust . Click on them to purchase and/or view the product items.

Where are they?

Weems and Whitcomb (1975) noted that, “on many occasions specimens have been inadvertently brought into Florida in trucks and automobiles, hidden in luggage, boxes, and various commercial cargoes, but to date it appears to have been unsuccessful in establishing breeding populations in Florida.”

Gertsch and Ennik (1983) reported a few records from Arizona, California, Colorado, Florida, Maine, Minnesota, New Jersey, New Mexico, New York, North Carolina, Wyoming and Tamaulipas (Mexico).

What do they look like?

The description is taken from Gertsch (1958). Adults of both sexes are similar in appearance and size, ranging from about 7 to 12 mm in body length. Adult females average slightly larger, about 9 mm compared to about 8 mm for adult males. In total, these markings appear in the form of a violin. In addition, three dusky patches may occur along the margin on each side. The sternum is yellowish, with other ventral body parts of the cephalothorax darker reddish brown.

Where do they hang out?

Most are found in buildings and outbuildings, especially in boxes and among papers, in every room from basement to attic. They were found in almost any place which had remained undisturbed for lengthy periods of time, such as behind pictures, beneath or behind furniture, in boxes of toys, in clothing, among stored papers, in the corrugations of cardboard boxes, and in discarded articles, such as tires, inner tubes, and assorted other junk. Most of the specimens found in feral conditions were under rocks, especially in bluff outcrops, with a few under bark or in logs. They definitely seemed to prefer dry conditions.

Bites and Bite Symptoms

Brown recluse spiders usually bite only when they become trapped next to the victim’s skin. Bites occur either when sleeping humans roll onto the spider or put on clothes into which the spider has crawled (Vetter and Visscher 1998). Typically bites occur under clothing, mostly on the thigh, upper arm, or lateral torso, less often on the neck (Anderson 1998).

Description of the symptoms is from Wingo (1960), Gorham (1968, 1970), Anderson (1982, 1998), and Vetter and Visscher (1998). Reactions to a bite vary from no noteworthy symptoms to severe necrosis or systemic effects. Discomfort may be felt immediately after the bite, or several hours may pass before any local reaction to the bite occurs. In one study, only 57% of the patients realized they had been bitten at the time of the bite.

Typical symptoms are as follows: Symptoms start two to six hours after the bite. Blisters frequently appear at the bite site, accompanied by severe pain and pronounced swelling. By 12 to 24 hours, it is usually apparent if a Loxosceles wound is going to become necrotic because it turns purple in color; if necrotic symptoms do not express by 48 to 96 hours, then they will not develop. If the skin turns purple, it will then turn black as cells die. Eventually the necrotic core falls away, leaving a deep pit that gradually fills with scar tissue.

•  There are about 1000 species of spiders in the United States. They live everywhere, even inside homes and buildings. The brown recluse and the widow spiders are considered venomous spiders; however, most spiders are not harmful to man.
• Spiders feed entirely on living insects or other animals, they may actively search for their prey, hide and wait for them to pass, or build webs to trap flying insects.

Control:

Non-Chemical Control of Spiders

 Outside lights should not be left on at night.  Trash, lumber piles, bricks, weeds, and outside structures are good breeding places for spiders and should be cleaned up. Inside the home spider webs should be brushed down. The egg sacs should be destroyed, vacuum cleaner attachments may be used to clean walls, and the collected debris should be destroyed.

Chemical Control of Spiders

Chemical control of spiders is difficult outdoors because web spinning spiders do not tend to contact treated surfaces. Inside the house, space sprays containing pyrethrins or pyrethroids are effective in killing spiders. Space sprays have little residual activity and should be applied when spiders are noticed. Dust formulations can be used in crawl spaces, attics, and utility areas to provide long-term protection. The insecticidal dusts tend to cling to the spider webs for long periods of time. When spiders chew their webs to recycle the silk they consume the toxicant and die.

I hope this helps anyone who reads this.
