Pest Identification Photos

7504.       Winnipeg, Manitoba. Canada

Number 7504.    This is a broad-nosed/short-snouted weevil (Coleoptera: Curculionidae; subfamily Entiminae). They sometimes enter buildings in search of shelter, but do no harm there. See Broad-nosed/short-snouted weevil detailed information .

7502.      Picture were taken by a friend near his home wanted to know what kind of spider this is because there are small children all around this area. Georgetown, Canada.

Number 7502.       This appears to be a common (American) house spider, Parasteatoda tepidariorum – see (American) house spider image . Although they belong to the same family (Theridiidae) as the infamous widow spiders, these are harmless to humans.

7500.    Montreal, Quebec Canada

Number 7500.     This appears to be a booklouse (Psocodea: Liposcelidae). These basically are nuisance pests, feeding primarily on mould spores including mould that grows from the paste used in the binding of old books and wallpaper, or sometimes they can even feed on the paste itself. They require high humidity in order to persist in an environment. See booklouse detailed information .

7498.    Richmond, BC. Canada

Number 7498.    This is a broad-nosed/short-snouted weevil (Coleoptera: Curculionidae; subfamily Entiminae). They often enter buildings in search of shelter, but do no harm there. See Broad-nosed/short-snouted weevil detailed information

7496.      Edmonton, Alberta. Canada

Number 7496.  The image most likely is a burrowing/burrower bug in the family Cydnidae; see burrowing bug detailed information .

7494.      Looks like a carpet beetle larvae without the fine hairs. I squished one and it had guts. Measures 8mm long by 3mm wide. Found half a dozen on the floor under the plastic garbage can against the kitchen wall. Thanks for the help. Sault Ste. Marie, Ontario. Canada

Number 7494. This appears to be a pupa of a muscoid fly such as a house fly. See House fly detailed information .

Number 7491.    This is a true fruit fly (Diptera: Tephritidae); it resembles a sunflower maggot fly, Strauzia longipennis – see True fruit fly detailed information

7489.     Started spotting these in random rooms along the baseboards. We have lived here 12 years and never seen anything like this…we have had sugar ants but that is all. Thank you. Delta, BC. Canada

Number 7489.   This is a weevil (Coleoptera: Curculionidae); it looks like one of the grain/granary weevils in the genus Sitophilus. If you have any dry seeds such as rice, wheat, or corn/maize in your house, you should check them for any signs of infestation. See Weevil detailed information .

7487.     Looked like the form of a black widow but was a metallic brown. Never seen one before. Peterborough, Ontario. Canada

Number 7487.    Most likely a comb-footed/cobweb spider (family Theridiidae) in the genus Steatoda. Related to widow spiders, they can deliver a very painful but not dangerous bite if mishandled (personal experience). See comb-footed/cobweb spider detailed information .

7484.      Courtenay, BC…very hot day in May…dozens of these on the back patio, most dead. Almost like an ant swarm? Courtenay, British Columbia. Canada

Number 7484.     This is a click beetle (Coleoptera: Elateridae); it looks like Agriotes lineatus – see click beetle image .

7482.     Found in basement suite. Saskatoon, Saskatchewan. Canada

Number 7482.    This is a terrestrial crustacean in the order Isopoda; they go by numerous common names, including sow bugs, woodlice, and roly-polys. They are for the most part harmless scavengers on decomposing organic matter. See Terrestrial Crustacean detailed information .

7480.      My client originally thought her cat and son’s dog had fleas and bought medication from us. The owner claims she gets bugs on herself and has developed a rash on her back. She had a fumigator come to her house and says it seemed a bit better since. Yesterday she brought us the bug in the picture. Is it a carpet beetle? What is the best way to get rid of them? Cochrane, Alberta. Canada

Number 7480.   This appears to be a larva of a dermestid beetle in the genus Trogoderma. They will feed on a very wide variety of seeds as well as dead insects and animals, cereal products, candy, cocoa, corn, corn meal, dog food (dried and ‘burgers’), fishmeal, flour, oatmeal, milk powder, spaghetti, spices, peas, wheat, barley, and pollen. In grain, they cannot feed on whole grain, but can feed on broken kernels that are usually present. The best control is prevention; start by examining all potentially infestable products in your home, discarding anything that appears to be infested. Then, give all storage areas a thorough cleaning. In the future, store all potentially infestable products in sealable glass, plastic, or metal containers.

7478.      I have been finding these beetles (?) crawling inside our house in random places at least once day for the past few weeks. They can fly but almost never do, move very slowly and are easy to pick up. Approx 5 mm in lengths. It is February, we live in Black Mountain area of Kelowna, lots of trees around. Kelowna, BC. Canada

Number 7478.    These are beetles in the family Dermestidae (hide/skin/carpet beetles and allies); it looks like Megatoma variegata, a species native to the Pacific Northwest – see Beetles – Dermestidae detail information

7477.      Not sure what those flies are, I have a few of them in the house ( bathroom, kitchen ). The weather is fairly cold at this time of the year. Could it come from one of my plants? Thank you. Gatineau, QC. Canada

Number 7477.     This appears to be a dark-winged fungous gnat (Diptera: Sciaridae). Although usually just nuisance pests, larvae of some species can damage roots and other soft plant tissues of potted plants that are in contact with soil. They need very moist/wet soil in order to thrive, so one of the simplest control measures is simply to let the soil dry out as much as practical between waterings. See Dark-winged fungus gnat control suggestions .

7475.     Found late at night in the kitchen walking (slowly) on the kitchen counter. Aproximately the size of an American dime. Pelham, Alabama. United States

Number 7475.     This is thread-legged bug (Hemiptera/Heteroptera: Reduviidae; subfamily Emesinae). Most are general predators on other small arthropods; some specialize on spiders, and may steal the spiders’ prey as well. Very interesting insects that many people never see.

7473.    Calgary, AB. Canada

Number 7473.    This appears to be a boxelder bug, Hemiptera/Heteroptera: Rhopalidae; Boisea sp., most likely a western boxelder bug, Boisea rubrolineata – see Boxelder bug clip

7471.    Ottawa, Ontario. Canada

Number 7471.    This is a weevil (Coleoptera: Curculionidae). If it is very small (less than 4 mm), it could be one of the granary weevils in the genus Sitophilus. Just to be safe, you should check all food storage areas for signs of insect infestation. See weevil detailed information 

7469.    Found indoors, in a ground floor condo, smaller than a grain of rice. Toronto, Ontario. Canada

Number 7469.    This appears to be one of the grain beetles (Coleoptera: Silvanidae) in the genus Oryzaephilus (saw-toothed and merchant grain beetles). They will infest a wide variety of dry stored food products, and nay become pantry pests – see Grain beetles detailed information .

7467.    This was crawling across my living room floor. Is it a bot fly larva? Can they just come into a home on their own? we have no pets or kids. Toronto, Ontario. Canada

Number 7467.  It is a mature bot fly (Diptera: Oestridae; subfamily Cuterebrinae) larva that has emerged from its host (most likely a rodent or rabbit) and is seeking a safe place to undergo pupation. These are incapable of entering buildings on their own. See Bot fly detailed information

7465.        Hanging in window, outside. Large! Elora, ON. Canada

Number 7465.    This is Argiope aurantia, a very common and widespread orb weaving spider (family Araneidae). Because of its very wide geographic range, it goes by a wide variety of common names. See Argiope aurantia examples . All orb weavers are harmless to humans.

7463.        It only come out in the light, very fast, around the sink. I’m in GA. I noticed it has a line but some don’t have a line. I tried putting peppermint oil around the counter but it does not fade this bug. Decatur, GA. United States

7461.        There is a swarm of these bugs dropping onto my back deck, car, roof just everywhere they land. The swarm is flying above some trees in my backyard. I am unable to identify them myself, hoping you guys can! Thanks 🙂 Port Hawkesbury, Nova Scotia. Canada

Number 7461.    This a winged ant, but I cannot tell which species it might be. Swarming of winged ants is just a part of their mating ritual – see Winged ant details .
