| Fleas |
Description:
Adult fleas are about 1/16 to 1/8-inch long, dark reddish-brown,
wingless, hard-bodied (difficult to crush between fingers),
have three pairs of legs (hind legs enlarged enabling jumping)
and are flattened vertically or side to side (bluegill or
sunfish-like) allowing easy movement between the hair, fur
or feathers of the host.
Fleas are excellent jumpers, leaping vertically up to seven
inches and horizontally thirteen inches. (An equivalent hop
for a human would be 250 feet vertically and 450 feet horizontally.)
They have piercing-sucking mouthparts and spines on the body
projecting backward. |
 |
Adult fleas are not only
a nuisance to humans and their pets, but can cause medical
problems including flea allergy dermatitis (FAD), tapeworms,
secondary skin irritations and, in extreme cases, anemia.
Although bites are rarely felt, it is the resulting irritation
caused by the flea salivary secretions that varies among individuals.
Some may witness a severe reaction (general rash or inflammation)
resulting in secondary infections caused by scratching the
irritated skin area. Others may show no reaction or irritation
acquired after repeated bites over several weeks or months.
Most bites usually found on the ankles and legs may cause
pain lasting a few minutes, hours or days depending on one's
sensitivity. The typical reaction to the bite is the formation
of a small, hard, red, slightly-raised (swollen) itching spot.
There is a single puncture point in the center of each spot.
(Ants and spiders leave two marks when they bite. Mosquitoes,
bees, wasps and bedbugs cause a large swelling or welt). Also,
fleas may transmit bubonic plague from rodent to rodent and
from rodent to humans.
Habits and Habitats:
Fleas pass through a complete life cycle consisting of egg,
larva, pupa and adult. A typical flea population consists
of 50 percent eggs, 35 percent larvae, 10 percent pupae and
5 percent adults. Completion of the life cycle from egg to
adult varies from two weeks to eight months depending on the
temperature, humidity, food, and species. Normally after a
blood meal, the female flea lays about 15 to 20 eggs per day
up to 600 in a lifetime usually on the host (dogs, cats, rats,
rabbits, mice, squirrels, chipmunks, raccoons, opossums, foxes,
chickens, humans, etc.). Eggs loosely laid in the hair coat,
drop out most anywhere especially where the host rests, sleeps
or nests (rugs, carpets, upholstered furniture, cat or dog
boxes, kennels, sand boxes, etc.). Eggs hatch in two days
to two weeks into larvae found indoors in floor cracks &
crevices, along baseboards, under rug edges and in furniture
or beds. Outdoor development occurs in sandy gravel soils
(moist sand boxes, dirt crawlspace under the house, under
shrubs, etc.) where the pet may rest or sleep. Sand and gravel
are very suitable for larval development which is the reason
fleas are erroneously called "sand fleas."
Larvae are blind, avoid light, pass through
three larval instars and take a week to several months to
develop. Their food consists of digested blood from adult
flea feces, dead skin, hair, feathers, and other organic debris.
(Larvae do not suck blood.) Pupa mature to adulthood within
a silken cocoon woven by the larva to which pet hair, carpet
fiber, dust, grass cuttings, and other debris adheres. In
about five to fourteen days, adult fleas emerge or may remain
resting in the cocoon until the detection of vibration (pet
and people movement), pressure (host animal lying down on
them), heat, noise, or carbon dioxide (meaning a potential
blood source is near). Most fleas overwinter in the larval
or pupal stage with survival and growth best during warm,
moist winters and spring.
Adult fleas cannot survive or lay eggs without
a blood meal, but may live from two months to one year without
feeding. There is often a desperate need for flea control
after a family has returned from a long vacation. The house
has been empty with no cat or dog around for fleas to feed
on. When the family and pets are gone, flea eggs hatch and
larvae pupate. The adult fleas fully developed inside the
pupal cocoon remains in a kind of "limbo" for a
long time until a blood source is near. The family returning
from vacation is immediately attacked by waiting hungry hordes
of fleas. (In just 30 days, 10 female fleas under ideal conditions
can multiply to over a quarter million different life stages.)
Newly emerged adult fleas live only about
one week if a blood meal is not obtained. However, completely
developed adult fleas can live for several months without
eating, so long as they do not emerge from their puparia.
Optimum temperatures for the flea's life cycle are 70°F
to 85°F and optimum humidity is 70 percent. The cat flea
is the most common flea in Ohio which feeds on a wide range
of hosts.
Control: Flea
control is best achieved with a simultaneous, coordinated
effort involving strict sanitation, pet treatment and premise
treatment (both indoors & outdoors).
Inspection - Before treatment, discuss the
pet's habits with family members to determine where resting
and sleeping occurs most frequently. Flea activity "hot
spots" can be detected by placing white socks over shoes
and walking through the residence into suspected areas. Research
has demonstrated that these areas will contain the highest
amount of eggs, larvae and pupae even after vacuuming. Hot
spots for homes with dogs are usually areas where the pet
goes in and out of the house, eats, sleeps and spends time
with the family at the base of furniture. For cats, check
the tops of refrigerators, cabinets, book cases and higher
locations.
Sanitation - Before vacuuming, collect all items (toys, shoes,
clothes, etc.) off the floor, under beds, furniture, in closets,
etc., to ensure best access for treatment. Also cover fish
tanks, remove bird cages, pet food and water dishes and wash
or dry clean any pet bedding. Vacuuming carpet with a beater-bar
type vacuum where the pet rests and sleeps will help control
flea larvae by removing eggs and dried blood feces (larval
food) plus opening up the carpet's nap for more effective
insecticide treatment. Vacuuming must be performed on a regular
basis every other day to be effective. Flea larvae do not
move far from the site of hatching when there is adequate
food (dried blood feces from adults). Research indicates larvae
spend 83 percent of the time deep in the carpet at the base
of fibers frequently becoming entwined within the carpet.
At pupation, the larva move up the carpet fiber spinning a
camouflaging cocoon around itself. Vacuum especially where
lint and pet hairs accumulate along baseboards, around carpet
edges, on ventilators, around heat registers, in floor cracks,
and under and in furniture where the pet sleeps.
After vacuuming, place the vacuum bag in
a large plastic garbage bag and discard in an outdoor trash
container. If the cleaner uses a liquid water medium in a
plastic pan (rather than a dust bag) discard dirty water far
away from the house.
Prevention - Trim lawns and weeds to create
a drier, less-ideal environment for flea larvae. Avoid piles
of sand and gravel around the home for long periods of time.
Fence yards to prevent dogs from roaming freely in heavily
infested areas or contacting other infested animals. Discourage
nesting or roosting of rodents and birds on or near the premises.
Screen or seal vents, chimneys, crevices, etc. where rats,
mice, squirrels, raccoons, chipmunks, etc. may use to enter
crawlspaces and buildings. Wash or destroy pet bedding, regularly
groom pets and vacuum frequently to remove up to 95 percent
of the flea eggs, some larvae and adults. Only about 20 percent
of the larvae might be removed when vacuuming since they wrap
themselves around the bottom strands of carpeting. |

| Honey Bees |
| DESCRIPTION: The honey bee is
covered with short, dense hair, usually golden-brown and black,
and its abdomen is striped. There are three castes of honey
bees in the colony: workers (2/5 to 3/5 inch long), drones (3/4
to 5/8 inch long), and the queen (3/5 to ¾ inch long).
HABITAT: Around flowers and
flowering trees
LIFE CYCLE: The queen is responsible
for reproduction. The drones are fertile male bees that mate
with new queens. The workers are sterile females responsible
for feeding the queen, maintaining the hive, gathering the
pollen and nectar, and protecting the hive.
TYPE OF DAMAGE: Honey bee workers
have a barbed stinger that becomes detached along with a venom
sac after the sting. |
 |
CONTROL:
When stung by a bee, immediately remove the stinger and venom
sac by gently scraping or flicking the stinger with a fingernail.
Do not use tweezers or try to squeeze out the stinger- this
pushes more venom into the wound. Next, wash the sting site
with soap and water. Apply ice to minimize pain and swelling.
If you experience anything more than a localized, normal reaction,
seek medical attention immediately. Sting victims should be
kept calm, quiet and inactive. In some cases, an allergy specialist
may advise a series of injections to lessen sensitivity for
persons with case histories of severe allergic reactions to
insect stings.
PREVENTION:
Wear proper clothing and use caution when worker honey bees
are foraging around houses on flowering trees and plants.
When flowers finish blooming, the danger will decrease. It
is best to allow swarms of honey bees to leave on their own.
A swarm of bees will remain clustered until scout bees have
located a suitable site for permanent nesting. In two days
or less, the swarm will usually break the cluster and fly
away. If it is necessary to remove a swarm, be sure to contact
a local beekeeper, who usually will be happy to get the bees.
(Contact your county extension office for a list of local
bee keepers.)
REMOVAL FROM BUILDINGS:
Honey bees are valuable pollinators of crops and other flowering
plants. There are situations, though, when our "beneficial"
honey bee can become a "nuisance" honey bee requiring
control. Treatment is only recommended when swarming bees
move their nest into a building, wall void, attic void, chimney,
garage or porch roof. Remember that after the honey bees are
killed, they must be removed with their comb nest along with
honey. Untended honey soon begins to decompose and/or seep
out of the comb, causing odor problems, staining walls or
ceilings, and encouraging secondary pest infestations by ants,
cockroaches, wax moths, flies, and dermestid beetles. Clean
the area with soap and water and let dry completely. Left
over odors from the previous colony can attract other bees
into the same location. Other bees in the area may try to
remove honey from the killed colony and the site is likely
to be recolonzied by other bees. Fill the void with insulation
or other material to keep it from being used as a nest site
again. |

| Roaches |
Description:
Most cockroaches have a flattened, oval shape, spiny legs,
and long, filamentous antennae. Immature stages are smaller,
have undeveloped wings and resemble the adults. Adult German
cockroaches are light tan to medium brown except for the shield
behind the head marked with two dark stripes (separated by
a lighter stripe), which run lengthwise on the body. Adults
are about 1/2 to 5/8-inch long and have wings, but rarely
fly. Wings cover the entire abdomen of females and all except
the abdominal tip in males. The male is light brown and rather
boat-shaped, whereas the female is slightly darker with a
broader, rounded posterior. Young roaches (nymphs) are wingless
and nearly black with a single light stripe, separating two
black bands, running down about halfway of the middle of the
back. Egg capsules are light tan and less than 1/4-inch long.
|
 |
These are the most common
roaches found in homes, apartments, restaurants, supermarkets,
hospitals, and other buildings where food is stored, prepared,
or served. They eat food of all kinds and may hitchhike into
the home on egg cartons, soft drink cartons, sacks of potatoes
or onions, used furniture, beer cases, etc. These roaches
will move from building to building during the warm summer
months. They can develop into large populations and live throughout
the home, especially in kitchens and bathrooms. Roaches can
foul food, damage wallpaper and books, eat glue from furniture,
and produce an unpleasant odor. Some homeowners are allergic
to roaches, and these pests can contaminate food with certain
bacterial diseases that result in food poisoning, dysentery,
or diarrhea. Cockroaches can cause childhood asthma.
Habitat and Habits:
German cockroach females, unlike most other roaches, carry
the egg capsule protruding from their abdomen until the eggs
are ready to hatch. The case is then dropped in a secluded
location, with the nymphs emerging within one day. A female
may produce four to eight cases during her lifetime, each
containing 30 to 48 eggs. Eggs hatch in about one month, and
nymphs develop in 1-1/2 to 4 months. Female roaches live about
6-1/2 months and males live slightly less. The German cockroach
produces more eggs and has more generations per year (three
to four) than other roaches, and only a few individuals are
needed to develop into troublesome infestations. This roach
is spread by commerce and transportation as well as mass migrations.
It is the most prevalent pest in the Apartment Industry in
the United States.
During the day, these roaches may be found
hiding, clustered behind baseboard molding, in cracks around
cabinets, closets or pantries, and in and under stoves, refrigerators
and dish washers. If clusters of roaches are seen during the
day, the population is large. Both nymphs and adults are very
active and capable of running rapidly. German cockroaches
have a high need for moisture and usually travel 10 to 12
feet from their harborage for food and water in kitchens,
bathrooms, utility rooms, etc., preferring darkness. Without
food or water, adults may die in two weeks, but can live a
month with only water.
Control: German
cockroaches can be detected by examining the premises after
dark with a flashlight. During the day, probing hiding places
with a wire or thin wood strip will expose roaches. Adults
and nymphs usually hide clustered together.
German roaches can move from one building
to the next during the summer, entering through cracks in
foundations, around loose-fitting doors or windows, and along
water and gas pipes. Repair leaky water faucets and pipes.
Seal openings such as cracks in foundation walls, exterior
walls around air conditioners, doors, windows, floors, ceilings,
around plumbing fixtures, electrical outlets, baseboards,
etc. with putty, plastic wood or other caulking material.
Inspect for roaches and their egg cases in sacks, cartons,
boxes, used appliances and furniture, etc., brought into the
home. Sanitation is critical in roach control. (Unclean living
conditions from housekeeping neglect is the major contributing
factor of roach outbreaks.) Clean areas beneath cabinets,
sinks, stoves, refrigerators, etc. as well as cupboards, pantry
shelves and food storage bins. Do not line cabinets with paper
products. Do not keep brown grocery casks around since they
are often contaminated with roach eggs. Roaches can thrive
in the dark warm folds of paper sacks. Clean up spilled foods
and liquids. Avoid leaving scraps of food on unwashed dishes
and countertops overnight. Keep food in tightly sealed containers,
rinse cans and bottles before putting in the trash, and transfer
garbage outdoors into roach-proof receptacles away from the
house. Leftover pet food should not remain in the feeding
dish overnight. Remember that "wet" pet food attracts
roaches faster than dry pet food. |

| Silverfish |
Description:
Silverfish are always wingless and are silvery to brown in
color because their bodies are covered with fine scales. They
are generally soft bodied. Adults are up to 3/4 inch long,
flattened from top to bottom, elongated and oval in shape,
have three long tail projections and two long antennae. |
 |
| Life
Cycle: Females lay eggs continuously after reaching
the adult stage and may lay over 100 eggs during her life.
Eggs are deposited singly or in small groups in cracks and
crevices and hatch in 3 to weeks. Silverfish develop from
egg to young to adult within 4 to 6 weeks and continue to
molt throughout their life. Immature stages appear similar
to adults except they are about 1/20 of an inch long when
they first hatch and whitish in color, taking on the adults’
silver coloring as they grow. They are long-lived, surviving
from two to eight years. Simple metamorphisis (egg, nymph,
adult).
Habitat, Food Source(s):
Silverfish are chewing insects and general feeders but prefer
carbohydrates and protein, including flour, dried meat, rolled
oats, paper and even glue. They can survive long periods,
sometimes over a year, without food but are sensitive to moisture
and require a high humidity (75% to 90%) to survive. They
also have a temperature preference between 70 and 80 degrees
F. They are fast running and mostly active at night and generally
prefer lower levels in homes, but may be found in attics.
Pest Status, Damage:
Primarily a nuisance pest inside the home or buildings; can
contaminate food, damage paper goods and stain clothing; medically
harmless. Many of their habits are similar to cockroaches
and they appear to be more common as household pests in drier
parts of the state. Occasionally damage book bindings, curtains,
wallpaper.
Control: Sanitation
only helps prevent a reinfestation after a population has
been eliminated. It alone cannot control silverfish or firebrats
and is only marginally effective in reducing their numbers.
However, a reduction in available water or relative humidity
is helpful in eliminating silverfish and firebrats. Dry out
or ventilate resting or shelter areas to reduce their moisture
level. Since these insects prefer darkness, lighting a sheltered
area sometimes forces them to migrate to sites where they
cannot survive or where they can be controlled more readily.
Apply insecticide sprays to sheltered areas,
cracks, crevices, around floor moldings, in and behind furniture
and in attics. Occasionally, large populations become established
in wall voids. It may be necessary to drill small holes in
the walls in order to treat inside them.
It is advisable to use the services of a
pest control operator when the infestations are large, persistent
and hard to find. A commercial operator has the knowledge,
training and equipment to perform safe and effective control. |
