Bed Bugs

Bed bugs are blood-feeding insects (Figures 1–3) that feed mainly on the blood of humans, but also suck blood from other animals, such as birds, bats, and rodents. Bed bugs usually feed at night when people are asleep because the hosts are unaware that they are being fed upon. As bed bugs feed (Figure 3), they inject a salivary secretion into the wound to prevent coagulation. This fluid often causes the skin to itch and become swollen. Scratching causes sores, which may become infected. Bed bugs are not known to transmit any human pathogens but can cause emotional distress to those affected.

When associated with humans, bed bugs generally infest dwellings such as houses, hotels, dormitories, and cruise ships, but have also been known to infest places such as subways, movie theaters, nursing homes, hospitals, and planes. During the day, bed bugs hide in cracks and crevices and can be found in wall outlets, behind baseboards, wallpaper, and pictures, between bed joints and slats, along the seams of mattresses, and in bed linens. The cryptic nature of bed bugs makes them difficult to detect and locate, making control a complex and laborious process that usually consists of an integrated approach that combines insecticides with other methods.

Bed bugs are transmitted from one place to another because they “hitchhike” on belongings such as clothes, suitcases, second-hand beds, furniture, and bedding. Female bed bugs disperse more than any other stage, so it is likely that the bed bugs that “hitchhike” on people’s belongings are mostly females. Because female bed bugs can store male sperm for four to six weeks, it is also likely that they are pregnant. Therefore, a single, pregnant female that is transferred to a different location can begin a new infestation. Severe bed bug infestations tend to have a sweetish, foul odor that is caused by an oily liquid they emit.

Life Cycle

The adult bed bug is about 1/4 inch long, flat, ovoid, and has no wings. It is generally brown except after a blood meal. The body then becomes swollen and the color changes to dark red from the ingested blood. One female can produce a total of 200 to 500 eggs in her lifetime, laying anywhere from 10 to 50 eggs at a time. The eggs are 1/25 inch long and are slightly curved. They are usually deposited in clusters and fastened to cracks and crevices or rough surfaces near adult harborages with a sticky cement-type substance.

The eggs hatch in one to three weeks. The newly hatched nymph is similar in shape to the adult but much smaller and straw-colored before feeding. The newly hatched nymphs and eggs can be very difficult to see without the use of magnifying equipment. The newly hatched nymph turns red or purple after getting a blood meal (Figure 4). There are five nymphal stages for bed bugs to reach maturity, which usually takes 35 to 48 days. Adult bed bugs can survive for six to seven months without a blood meal and have been known to live in abandoned houses for one year. In some cases they survive without humans by attacking birds and rodents.

Detection

Because there are so many possible harborages for bed bugs, detection of the pest can be difficult. It is especially difficult to locate small, early infestations of bed bugs because of their cryptic behavior. To complicate matters, many people have delayed reactions to bed bug bites, and some people do not react to the bites at all, making it almost impossible to determine the specific timeframe a person was exposed to an infestation. These factors make it difficult to detect early infestations until the populations are excessive and overwhelming, but early detection makes control cheaper and more successful.

One successful method of detection is by the use of bed bug–detecting canines (Figure 5). They can be an essential tool for detection in places with a lot of rooms and a high turnover, such as hotels, cruise ships, and dormitories. The ability to locate bed bug infestations before customer complaints can lower the possibility of litigation. Bed bug-detecting canines can also locate early infestations, even as few as one adult bed bug, leading to cheaper and more successful control.

Monitoring devices can also be used for detection of bed bugs. Sticky traps placed around beds and sofas can potentially confirm an infestation. There are also monitoring systems available that use carbon dioxide and heat as attractants.

Control

Once bed bugs are found, there are several methods that may be used to combat them, some old and some new (Table 1), although combining many methods usually yields the best result. No matter what methods are utilized by the pest control companies, there are many steps that can be taken by the homeowners to optimize the possibility for success. First, as many bed bugs as possible should be physically removed from the premises. This is accomplished by vacuuming all the carpets as well as visible bed bugs from the furniture. Once finished, ensure the vacuum bag is removed, sealed, placed in a zip lock bag, and placed in a deep freezer for at least a week. The four posts of the bed can then be placed in glass dishes or traps. Bed bugs cannot climb smooth surfaces, so the glass dishes will exclude more bed bugs from being able to infest the bed, as long as the bed is away from the walls and covers are kept from touching the floor. All bedding should be laundered with soap and a borax additive and dried at a high temperature. Clothing, pillows and drapery should be dry-cleaned. Also, contents inside dresser drawers should be emptied in order for insecticides to be sprayed under the drawers.

 

Insecticides

Insecticides are one option of control, but bed bugs can be extremely difficult to kill with insecticides. Unlike cockroaches (Figure 6), bed bugs do not have sticky pads on their tarsae (feet). When they crawl across residues of insecticide on surfaces, not much pesticide adheres to their bodies and, therefore, it does not kill them. In order to be effective, most insecticides must be applied directly to the insect. This requires searching for every bed bug in a room and spraying it directly. Remember, just because they are bed bugs does not mean they cannot feed and live in other places, such as a couches or recliners. Of course, this process of finding the bug and spraying it is very labor intensive. Most pest control companies budget about five to 10 hours to treat a typical bedroom. Because eggs may not be affected by the spray, the treatment must be repeated after about two weeks to kill newly hatched nymphs.

Dust formulations provide more residual effectiveness than sprays because dusts are more easily transferred from surfaces than sprays. Therefore, dust formulations are usually preferred over sprays for bed bug control. Insect growth regulators (IGRs) have also been tested for use on bed bugs but have yielded conflicting results in studies. A number of pesticides are available for use, as referenced by Table 2. They should always be used in accordance with the manufacturers’ labels. Insecticides can be classified by the mode of application: Mattress and Crack-and-Crevice, Indoor Surface, Indoor Space, and Fumigation. It is important to distinguish the differences among the categories in order to provide the most effective treatment.

Mattress and Crack-and-Crevice

This application is for areas that are normally inconspicuous and difficult to reach. Pesticide dusts and some sprays fall into this category. Dust can be applied using either a puff duster or a paint brush. Dusts are lighter and can penetrate farther than insecticide sprays. Therefore, they should always be used in areas where there are deep cracks and crevices and behind electrical outlets. NEVER SPRAY INSECTICIDES DIRECTLY ON OR IN ELECTRICAL OUTLETS, AND NEVER SPRAY INSECTICIDES DIRECTLY ON MATTRESSES UNLESS THAT USE IS SPECIFIED ON THE LABEL! Remove outlet covers and apply dust into the wall void. Dusts are also preferred over sprays when treating the tufts, folds, and sleeping surfaces of mattresses.

Indoor Surface

This application is for areas where the bed bugs are likely to crawl en route to either their harborages or to where they feed. This type of application is often referred to as residual sprays. They are designed to remain active for an extended period of time to maximize the effectiveness of the application. These sprays should be applied to the bed frame and the nonsleeping surfaces of mattresses. Dresser drawers should be removed and turned upside down, ensuring all surfaces are sprayed. Spray baseboards and under the edge of carpet around the entire perimeter of the room.

Indoor Space

This application is used to kill exposed insects on contact. These insecticides are often in the form of aerosols. When harborages are found, spray the insecticide in the air in the vicinity toward the bed bugs. Aerosols are preferred when treating sensitive materials such as clothing or stuffed animals. Sensitive items can be placed into a plastic garbage bag or a closet (which is also likely to be infested). Spray aerosol into the closet or bag and seal for 10 to 15 minutes.

Fumigation

This is an application of lethal gas to an enclosed structure to eliminate pests. During fumigation, the building must be emptied of all inhabitants for a certain time period. Although it can be costly, fumigation kills every stage of bed bugs including eggs, and should be considered in severe infestations. If total building fumigation is not possible, containerized fumigation may be an option. This method involves the transfer of furniture and other items into a trailer truck or similar container, after which the container and its contents are fumigated. Other control methods are applied inside the building during the fumigation process. It is important to note that using fumigation alone leaves no residual and so cannot help prevent a reinfestation.

Resistance

Bed bugs are known to be resistant to many insecticides, especially pyrethroids. This means that some bed bug populations may not be killed with pyrethroid insecticides. This may be due to cross resistance to DDT. Bed bugs were first reported to be resistant to DDT in the 1950s. Research shows that the organophosphates and carbamates are still effective, but are not registered for use indoors.

Nonchemical control

These methods can include physical removal as discussed earlier, and sealing the mattress and box springs in mattress encasements to ensure any missed bed bugs do not attempt to reestablish themselves. The use of mattress encasements also makes bed bug inspections easier and eliminates the bed as a possible harborage site. If encasements are used, be sure to purchase brands that say they are “bite proof” as well as “escape proof.” Another effective technique is exclusion by placing glass barriers around the bedposts and keeping the bed frame away from adjacent walls.

Heat is a control method that has been utilized since the early 1900s. Bed bugs die at temperatures above 45°C, which is about 113°F. McDonald pest control company  heat treatment to kill bed bugs,
