When I removed the window AC before winter arrived, I found about 20 stink bugs were hiding in the fold of my window curtains in my bedroom. They don’t really do much and don’t carry diseases, but do have an odor, which can increase if scared or harmed, so I collected them and left the jar outside to let them live. Over the last few months I’ve noticed them around the house, in my office, and in local stores this year more than previous years. They aren’t that small, compared to say an ant, so it’s curious how they seem to make their way into so many buildings throughout Connecticut. It seems as though this year they have higher numbers than of years past, so it has become more of a nuisance.
Stink bugs have only been in the Connecticut are for a couple decades, which is still fairly new in the insect world. They are surprisingly resilient to pesticides, but because they are not harmful, we don’t suggest using pesticides to kill them unless it is a true infestation. In most cases they are fairly inactive and easing them into a container to bring them outside is a simple solution; many people choose to use a vacuum, though they can potentially escape a vacuum and you may notice their odor lingers.
Our inspections and treatments can help to prevent stink bugs (and other bugs) from getting into your home or business. We look for gaps, poor seals, holes in screens, and other ways pest may be entering.

Many people think pests aren’t as big of an issue in the winter in New England, but it is more common for rodents to find their way in to homes and businesses. Rodents reproduce quickly, have a strong odor if they die in hidden places, and carry up to 35 different diseases. Mice, rats, squirrels, and even raccoons have been known to make their way into homes and businesses.
Signs you’ve got unwanted company. Typically, rodents are nocturnal, so often your first sign that they have moved in will be hearing them at night in walls or ceilings. It may be more difficult knowing by sound in a business because most businesses are closed during a rodent’s most active hours. Some other signs to help you determine if you have a rodent problem, consider what may be good nesting material sitting around or stored and see if there is any damage from nibbling, such as blankets, pillows, boxes, or newspapers, also look for droppings in areas where food may be near.
How we help. If you have a rodent issue, we will inspect your property for potential ways they are entering the premises, and put traps in locations most likely to rid you of your problem. All of our rodent services include a free followup visit to check and remove traps, as well as review how the issue has improved.
Cockroaches are among the hardiest insects. Some species are capable of remaining active for a month without food and are able to survive on limited resources, such as the glue from the back of postage stamps. Some can go without air for 45 minutes. Japanese cockroach (Periplaneta japonica) nymphs, which hibernate in cold winters, survived twelve hours at −5 °C to −8 °C in laboratory experiments.
Experiments on decapitated specimens of several species of cockroach found a variety of behavioral functionality remained, including shock avoidance and escape behavior, although many insects other than cockroaches are also able to survive decapitation, and popular claims of the longevity of headless cockroaches do not appear to be based on published research. The severed head is able to survive and wave its antennae for several hours, or longer when refrigerated and given nutrients.
It is popularly suggested that cockroaches will “inherit the earth” if humanity destroys itself in a nuclear war. Cockroaches do indeed have a much higher radiation resistance than vertebrates, with the lethal dose perhaps six to 15 times that for humans. However, they are not exceptionally radiation-resistant compared to other insects, such as the fruit fly.
The cockroach’s ability to withstand radiation better than human beings can be explained through the cell cycle. Cells are most vulnerable to the effects of radiation when they are dividing. A cockroach’s cells divide only once each time it molts, which is weekly at most in a juvenile roach. Since not all cockroaches would be molting at the same time, many would be unaffected by an acute burst of radiation, but lingering radioactive fallout would still be harmful.
The Blattodea include some thirty species of cockroaches associated with humans; these species are atypical of the thousands of species in the order. They feed on human and pet food and can leave an offensive odor. They can passively transport pathogenic microbes on their body surfaces, particularly in environments such as hospitals. Cockroaches are linked with allergic reactions in humans. One of the proteins that trigger allergic reactions is tropomyosin. These allergens are also linked with asthma. About 60% of asthma patients in Chicago are also sensitive to cockroach allergens. Studies similar to this have been done globally and all the results are similar. Cockroaches can live for a few days up to a month without food, so just because no cockroaches are visible in a home does not mean they are not there. Approximately 20-48% of homes with no visible sign of cockroaches have detectable cockroach allergens in dust.
Mice can have 10-12 babies a month.
The average gestation period is 20 days. A fertile postpartum estrus occurs 14–24 hours following parturition, and simultaneous lactation and gestation prolongs gestation 3–10 days owing to delayed implantation. The average litter size is 10–12 during optimum production, but is highly strain-dependent. As a general rule, inbred mice tend to have longer gestation periods and smaller litters than outbred and hybrid mice. The young are called pups and weigh 0.5–1.5 g (0.018–0.053 oz) at birth, are hairless, and have closed eyelids and ears. Cannibalism is uncommon, but females should not be disturbed during parturition and for at least 2 days postpartum. Pups are weaned at 3 weeks of age; weaning weight is 10–12 g (0.35–0.42 oz). If the postpartum estrus is not utilized, the female resumes cycling 2–5 days post-weaning.
Rats have long been considered deadly pests. Once considered a modern myth, the rat flood in India has now been verified. Indeed, every fifty years, armies of bamboo rats descend upon rural areas and devour everything in their path. Rats have long been held up as the chief villain in the spread of the Bubonic Plague, however recent studies show that they alone could not account for the rapid spread of the disease through Europe in the Middle Ages. Still, the Center for Disease Control does list nearly a dozen diseases directly linked to rats. Most urban areas battle rat infestations. Rats in New York City are famous for their size and prevalence. The urban legend that the rat population in Manhattan equals that of its human population (a myth definitively refuted by Robert Sullivan in his book “Rats”) speaks volumes about New Yorkers’ awareness of the presence, and on occasion boldness and cleverness, of the rodents. New York has specific regulations for getting rid of rats—multi-family residences and commercial businesses must use a specially trained and licensed exterminator. Rats have the ability to swim up sewer pipes into toilets. Rat infestations occur around pipes, behind walls and near garbage cans.
In the United States, cities tend to be breeding grounds for rat infestations and according to a 2015 study by the American Housing Survey (AHS) found that 18% of the homes in Philadelphia found evidence of rodents. This was followed by Boston, New York City, and then Washington DC as the cities with the largest rat and mice problems.
Hornets, like many social wasps, can mobilize the entire nest to sting in defense, which is highly dangerous to humans and other animals. The attack pheromone is released in case of threat to the nest. In the case of the Asian giant hornet (Vespa mandarina) this is also used to mobilize many workers at once when attacking colonies of their prey, honey bees and other Vespa species. Three biologically active chemicals, 2-pentanol, 3-methyl-1-butanol, and 1-methylbutyl 3-methylbutanoate, have been identified for this species. In field tests, 2-pentanol alone triggered mild alarm and defensive behavior, but adding the other two compounds increased aggressiveness in a synergistic effect. In the European hornet (Vespa crabro) the major compound of the alarm pheromone is 2-methyl-3-butene-2-ol.
If a hornet is killed near a nest it may release pheromones that can cause the other hornets to attack. Materials that come in contact with this pheromone, such as clothes, skin, and dead prey or hornets, can also trigger an attack, as can certain food flavorings, such as banana and apple flavorings, and fragrances that contain C5 alcohols and C10 esters.
Hornets have stings used to kill prey and defend hives. Hornet stings are more painful to humans than typical wasp stings because hornet venom contains a large amount (5%) of acetylcholine. Individual hornets can sting repeatedly; unlike honey bees, hornets and wasps do not die after stinging because their stingers are not barbed and are not pulled out of their bodies.
The toxicity of hornet stings varies according to hornet species; some deliver just a typical insect sting, while others are among the most venomous known insects. Single hornet stings are not in themselves fatal, except sometimes to allergic victims. Multiple stings by non-European hornets may be fatal because of highly toxic species-specific components of their venom.
The stings of the Asian giant hornet (Vespa mandarinia) are among the most venomous known, and are thought to cause 30–50 human deaths annually in Japan. Between July and September 2013, hornet stings caused the death of 42 people in China. Asian giant hornet’s venom can cause allergic reactions and multiple organ failure leading to death, though dialysis can be used to remove the toxins from the bloodstream.
People who are allergic to wasp venom are also allergic to hornet stings. Allergic reactions are commonly treated with epinephrine (adrenaline) injection using a device such as an epinephrine autoinjector, with prompt follow-up treatment in a hospital. In severe cases, allergic individuals may go into anaphylactic shock and die unless treated promptly.
In Jewish tradition, it was once believed that the sting of a hornet could be soothed by crushing a housefly and applying it to the site of the wound.
Some ant species are considered as pests, primarily those that occur in human habitations, where their presence is often problematic. For example, the presence of ants would be undesirable in sterile places such as hospitals or kitchens. Some species or genera commonly categorized as pests include the Argentine ant, pavement ant, yellow crazy ant, banded sugar ant, Pharaoh ant, carpenter ants, odorous house ant, red imported fire ant, and European fire ant. Some ants will raid stored food, others may damage indoor structures, some can damage agricultural crops directly (or by aiding sucking pests), and some will sting or bite. The adaptive nature of ant colonies make it nearly impossible to eliminate entire colonies and most pest management practices aim to control local populations and tend to be temporary solutions. Ant populations are managed by a combination of approaches that make use of chemical, biological and physical methods. Chemical methods include the use of insecticidal bait which is gathered by ants as food and brought back to the nest where the poison is inadvertently spread to other colony members through trophallaxis. Management is based on the species and techniques can vary according to the location and circumstance.
Bed bugs are obligatory hematophagous (bloodsucking) insects. Most species feed on humans only when other prey are unavailable. They obtain all the additional moisture they need from water vapor in the surrounding air. Bed bugs are attracted to their hosts primarily by carbon dioxide, secondarily by warmth, and also by certain chemicals. Bedbugs prefer exposed skin, preferably the face, neck, and arms of a sleeping person.
Bedbugs have mouth parts that saw through the skin, and inject saliva with anticoagulants and painkillers. Sensitivity of humans varies from extreme allergic reaction to no reaction at all (about 20%). The bite usually produces a swelling with no red spot, but when many bugs feed on a small area, reddish spots may appear after the swelling subsides.
Although under certain cool conditions adult bed bugs can live for over a year without feeding, under typically warm conditions they try to feed at five- to ten-day intervals, and adults can survive for about five months without food. Younger instars cannot survive nearly as long, though even the vulnerable newly hatched first instars can survive for weeks without taking a blood meal.
At the 57th annual meeting of the Entomological Society of America in 2009, newer generations of pesticide-resistant bed bugs in Virginia were reported to survive only two months without feeding.
DNA from human blood meals can be recovered from bed bugs for up to 90 days, which mean they can be used for forensic purposes in identifying on whom the bed bugs have fed.
