Bed Bugs Have Favorite Colors

Did you know bed bugs might have favorite colors?  A recent study conducted by researchers at the University of Florida and Union College determined that bed bugs are more prone to hide or live in certain places if they are specific colors.  If you have a lot of furniture in these colors, take caution!

Bed Bugs Drawn to Certain Colors, Study Shows

New research published in the Journal of Medical Entomology shows that bed bugs strongly preferred red and black, and they seemed to avoid colors like green and yellow.

April 27, 2016

Researchers from the University of Florida and Union College in Lincoln, Neb., wondered whether bed bugs preferred certain colors for their hiding places, so they did some testing in the lab. The tests consisted of using small tent-like harborages that were made from colored cardstock and placed in Petri dishes. A bed bug was then placed in the middle of the Petri dish and given ten minutes to choose one of the colored harborages. A few variations of the test were also conducted, such as testing bed bugs in different life stages, of different sexes, individual bugs versus groups of bugs, and fed bugs versus hungry bugs.

The results, which are published in the Journal of Medical Entomology, showed that the bed bugs strongly preferred red and black, and they seemed to avoid colors like green and yellow.

Bed Bug Bites

At Arizona Heat Pest Services we are able to effectively remove bed bugs from your house or office.  However, we do not offer treatments if you have been bitten by bed bugs.  This article comes in handy with this aspect because there are home remedies you can try yourself to cure your bites.

How to Treat Bed Bug Bites

 Naturally the first thing you will need to do if you have been bitten by a bed bug is to start a program to rid bed bugs from your home. These persistent little pests will only grow in number very quickly if you do not learn how to get bed bugs out of your house.

We will all react very differently to the bite of a bed bug, for a lucky few there is very little or no reaction and these people will hardly be aware of a pest problem in their home. Other individuals will react very badly and can be covered from head to foot with large ugly, red welts that drive them mad with the itching.

The most important thing to keep in mind if you are the victim of bed bug bites is that you must not scratch them. This may be very difficult for anyone who reacts badly to these bites, but to prevent possible further infections from breaking the skin you must resist the urge to rub and scratch the bites.

A Vacuum for Bed Bugs

French scientists have created  a vacuum for bed bugs.  This method has been attempted before using other types of suction, but now a more powerful method exists.  If put out for use, the creators of this vacuum hope the bed bugs collected can be used for examination and data collection.

New device may help collect bed bugs safely and effectively

In recent years, bed bugs (Cimex lectularius) have been appearing more and more often in beds around the world, and entomologists need specimens for research purposes.

Scientists in France have developed a tool that will aid this research, and their device is described in an article called “A High-Performance Vacuum Cleaner for Bed Bug Sampling: A Useful Tool for Medical Entomology” that was published in the Journal of Medical Entomology.

“The need for bed bug amelioration requires increased bed bug monitoring and control,” they wrote. “To increase monitoring and control levels, laboratory research on this pest insect is required for the development of innovative strategies and tools to eliminate bed bug infestations. Prior to developing laboratory experimental protocols to control bed bugs, field collection of this insect is necessary.”

With the goal of collecting bed bugs to be used in laboratory research, they modified a Dyson hand vacuum (model DC34) with a sampling vial and a nozzle and created a device that proved to be effective at collecting bed bugs. In a bed bug-infested apartment where the device was tested, it collected more than 700 bed bugs in under 15 minutes, including adults, larvae, and eggs.

Researchers describe how bed bugs break down insecticides

If you have been using insecticides to combat against insects like bed bugs, you might want to think again.  A recent study has been published stating that bed bugs can resist the chemicals and even break them down.  Until there are new household available insecticides created, we recommend leaving removal up to the professionals!

There are many reasons why bed bugs have made a comeback in recent decades, and their resistance to commonly used insecticides is one of the most widely accepted explanations.

In a new paper published in the Journal of Economic Entomology, scientists from the University of Sydney and NSW Health Pathology describe how bed bugs are able to resist pyrethroid insecticides via metabolic detoxification, the process by which bed bugs break down insecticides.

The researchers focused on two types of detoxification enzymes, which are broadly known as esterases and oxidases. These two types of enzymes change the chemical composition of insecticides so that they’re less harmful to the insect.

To understand which enzyme type might be responsible for resistance to commonly used insecticides, chemicals called synergists can be used. Synergists can inhibit or lower the levels of detoxifying enzymes, thereby increasing the toxicity of the insecticide. By using different types of synergists, it is possible to determine which enzymes may be present.

One of the most widely used synergists is a chemical called piperonyl butoxide (or PBO), which can inhibit both esterases and oxidases, but that ability in turn makes it hard to determine which enzyme type is contributing to the resistance.

However, a new synergist known as EN16/5-1 only inhibits oxidases, and not esterases, so it provides an opportunity to investigate the role of metabolic resistance and to determine which enzyme type may be responsible for resistance.
