Household Pests

crickets spiders

CRICKETS are usually a seasonal pest. If you treat for them in the Spring when they are the size of an ant you can prevent them from over taking the cool days of Autumn.

SPIDERS are helpful exterminator’s in our world. They spin their webs to catch food BUT no one likes unwanted guest hanging around.

CAMEL BACK CRICKETS look a lot like spiders but are in fact crickets, and are usually found in wet areas such as laundry rooms, bathrooms and tubs.

Century Termite and Pest can treat for crickets, spiders and camel back crickets. We power spray the perimeter of your home and also treat the interior. We want to put the barrier up to get them coming and going.


Adult centipedes are yellowish to dark brown, often with dark markings, and 1/8 to 6 inches long. The body is flattened with 15 to 177 body segments which typically have one pair of legs each. The house centipede is grey-yellow with three stripes down the back and has very long legs banded with white. The largest centipedes are found in the Southwest.

Centipede Biology
Centipedes typically winter over outdoors, and, in the summer lay 35 eggs or more in or on the soil. Newly hatched centipedes have four pairs of legs; during subsequent molts, the centipede progressively increases the number of legs until becoming adult. Adults of many species live a year and some as long as five to six years.

Centipedes, including the house centipede, prefer to live in moist environments. The house centipede can live indoors in a damp basements, moist closets, and bathrooms and outdoors under stones, decaying firewood, objects on the ground, piles of leaves, mulch, etc. Most centipedes are active at night. The first pair of legs on centipedes has poison glands which are used to kill prey, such as insects and spiders. They obtain most of their water from their prey. Centipedes can bite humans, but the bite is seldom worse than a bee sting.


Crickets of the family Gryllidae (also known as “true crickets”), are insects somewhat related to grasshoppers, though more closely related to katydids or bush crickets. They have rather flattened bodies and long antennae. There are about 900 species of crickets worldwide. They tend to be nocturnal and are often confused with grasshoppers because they have a similar body structure including large hind legs used for jumping. Crickets are harmless to humans.

Only male crickets chirp. Along the bottom of each wing is a large vein with “teeth,” much like the teeth of a comb. They run the top of one wing along the teeth at the bottom of the other wing to generate the chirp — not by rubbing their legs together, as many people believe. As he does this, the cricket also holds the wings up and open. This allows the wings themselves to act as acoustical reflectors.

Like all other insects, crickets are cold-blooded, which means that they take on the temperature of their surroundings. As the temperature rises, it becomes easier to contract the muscles used to produce the chirping and the chirping speeds up; as the temperature falls it slows down. So, it’s somewhat true that you can tell how hot a night is by the speed of the cricket‘s chirp.

Crickets are omnivores and scavengers. They feed on organic materials, as well as decaying plant material, fungi, and some plant seedlings. They’ve also been known to eat their own dead when there is no other source of food available — to the extent that they will exhibit predatory behavior toward other weakened or dying crickets.

Crickets mate in late summer and lay their eggs in the fall. The eggs hatch in the spring and have been estimated to number as high as 2,000 per fertile female. Female crickets have a long needle-like egg-laying organ called an “ovipositor”.

Crickets are popular pets and are considered to bring good luck in some countries. In China, crickets are sometimes kept in elaborate cages. It is also common to find them as caged pets in some European countries, particularly in Spain and Portugal. In Southeast Asia and elsewhere, cricket fighting has been a betting sport for thousand of years.


Silverfish are primitive (i.e., older than cockroaches), wingless insects that are 1/2-inch long when fully grown. They are covered with silvery scales and are flattened and somewhat “carrot” shaped. Three long, slender “antennae-like” appendages project from the end of the abdomen giving them the name “bristle tails.”

The female lays one to three eggs per day in crevices or under objects. The female molts after laying a batch eggs and sheds her skin as many as 50 times after becoming an adult. The eggs hatch in about 43 days at 72-90 F and at least 50-75% relative humidity. The young silverfish look exactly like the adults, except smaller, and feed on the same foods. Under ideal conditions, they molt every two to three weeks becoming adults in the three to four months. However, under poor conditions, this might require two to three years. These insects are very long-lived, commonly living at least three years. The silverfish are unlike most of the other insects in that they continue to molt after they become adults.

Silverfish are tropical insects that easily adapt to the structural environment. They live in warm (71-90 F), moist locations in the structures; hide during the day; and rest in tight cracks and crevices. They roam great distances looking for food, but once a food source is located, they remain close until the supply is exhausted. They can be found throughout a structure from the basement to individual floors to attics to shingles on the roof. They readily feed on books, cloth, and sometimes dried meats or dead insects. They seem to be especially fond of the sizing on books and paper, and the glues and pastes found on wallpaper, labels, and paper products.

During the inspection, look for activity in areas that provide moisture, shelter and food. Reducing moisture, lowering the temperature, and removing infested items can help eliminate localized infestations. Sanitation is helpful but may not greatly reduce the problem because these pests feed on so many paper products. They can survive for weeks without food and water.


There are over 35,000 species of spiders worldwide, with about 3,000 occurring in North America. Many species of spiders are household pests. Wherever their food is available, spiders are likely to be found. All spiders are predators, feeding mainly on insects and other small arthropods. Controlling spiders involves a six step process:

household pest spider

A thorough inspection of the building or household.

Accurate identification is important for both pest management and medical reasons.

This consists of making sure that the building or home is in good physical condition, and properly screened and sealed to reduce entry. Also, in homes changing the bulbs near the entrances to yellow bulbs, may be of some help in reducing attractiveness.

Such practices consists of keeping the premises free of debris such as boxes, papers, clothing, scrap and lumber piles, etc.; it is wise to wear protective gloves and clothing when cleaning out such accumulations of clutter. A thorough housecleaning should be done twice each year.

Mechanical Measures
The key to control is the timely mechanical removal of spiders, webs, but especially the egg sacks with a vacuum, both inside and outside; seal and dispose of the bag immediately. If a broom is used for the removal, then it is suggested that if a spider is present on the web that an appropriate labeled flusher be used for a quick contact kill before removal of the web.

Pesticide Application
If desired, chemical control consists of the application of appropriately labeled dusts, wettable powders, micro encapsulated, or lacquer pesticides in typical spider harbor ages. If web-building spiders are the problem, lightly dusting the web with a non-repellent dust is very effective because these spiders recycle their silk.
