7492.      I found this on the inside of our screened in deck, hence the name I gave it. I have never seen one of these before and I am almost n74 years old. Just curious. Thanks. y Road, River Philip, NS. Canada


Number 7492.    This is a fishfly (Megaloptera: Corydalidae; subfamily Chauliodinae). See Fishfly for details on the life history of a representative species.


True fruit fly

7491.      On June 8, 2024, found this flying insect on a red runner bean leaf in my garden. Not familiar with it. Wondering what it is attracted to or eating? Toronto, ON. Canada


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


Ichneumon wasp

7490.       Lac LA hache, British Columbia. Canada


Number 7490.    This is an ichneumon wasp (Hymenoptera; Ichneumonidae); it looks like one in the subfamily Ophioninae. These wasps all are parasitic on other arthropods, mainly other insects; they are non-venomous and harmless to humans. See Ichneumon wasp 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 .



7488.      Found among my clothing. Township of Madawaska Valley, Ontario. Canada


Number 7488.    This is a pseudoscorpion, a non-venomous arachnid related to true scorpions, spiders, etc. They are general predators on other small invertebrates and entirely harmless to humans. See pseudoscorpion detailed information .

Grain beetle

7486.      What kind of bug is this. Was crawling on my arm while watching tv in bed. Port Hope, Ontario. Canada


Number 7486.    This is a grain beetle (Coleoptera: Silvanidae) in the genus Oryzaephilus, either a saw-toothed or merchant grain beetle. These can infest a wide vsriety of dry stored food products, so you should check your pantry for any signs of insect infestation. See Grain Beetle detailed information.

Larva of a dermestid beetle

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.


Grain beetles

7479.       Found in kitchen pantry. Also appears to have burrowed in charcuterie board. Burlington, Ontario. Canada


Number 7479.  This appears to be one of the grain beetles in the genus Oryzaephilus (Coleoptera: Silvanidae). They can be pests in dry stored food products such as flour, baking mixes, dry cereals, dry pet food, etc. I suggest inspecting your food storage areas for any signs of insect infestation. See Grain beetles detailed information 


Beetles – Dermestidae

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


Bed Bugs

A friend of mine recently had bed bugs. Thankfully, it seems they were caught early, and after two sprays two weeks apart they seem to be gone. Erring on the side of caution, I’m wondering when it will be safe to have my friend over to my place again, or to go visit him at his place? I know bed bugs aren’t exactly “contagious” but I’m concerned about one possibly hitching a ride on a jacket, tote bag, backpack, etc. And, of course, I don’t want to make my friend feel bad. I can’t find any good information online about this. Could you please help me out? Toronto

Don’t take/wear anything with you that you cannot fit into a large (contractor size) plastic bag after your visit. Then see for suggestions on using either heat or cold to kill any unwanted hitchhikers.

German cockroaches

Adult German cockroach was seen and killed on Dec 16 but my son had seen small dark bugs in the kitchen about a week ago. The place was sprayed yesterday on Dec 21st. They notified us that no further treatments were required. Will one treatment get rid of all of them? Where can I buy bait etc. to ensure none survived? I’ve looked and looked and I can’t find anything in Canada.

German cockroaches are notoriously difficult to bring under complete control. I suggest using ‘Roach Motels’ as monitoring devices, and if cockroaches show up in them, schedule another treatment. In the meantime, the insect growth regulator (IGR) Pyriproxyfen should be available in Canada – see It usually is marketed under the brand name NyGuard.


Can a larva get inside a humans ears and mouth? Gulfport Mississippi

Yes, this can occur, but very uncommonly, and then usually associated with other underlying factors. See and for oral (mouth) and for aural/otic (ear) cases.

Dark-winged fungus gnat

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 .



7476.     Port au Choix, Newfoundland and Labrador. Canada


Number 7476.    This is a moth in the family Geometridae; their caterpillars are known as loopers, inchworms, or spanworms. This is a huge family, but only a few specie are serious pests. See Geometridae Video Clip


Thread-legged bug

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.


larva of carpet beetle

7474.    3 mm long insect found next to my grandpas day bed. Vancouver, BC. Canada


Number 7474.    This appears to be a partial larva of carpet beetle (Coleoptera: Dermestidae) in the genus Anthrenus. See carpet beetle control suggestions .


Boxelder bug

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


Leaf-footed bug

7472.     Saw this near our trash inside our home today. wondering if it’s a kissing bug? It’s my first time seeing this so I’m a little bit worried cause I have kids around. London, Ontario. Canada


Number 7472.    This is a harmless leaf-footed bug (Hemiptera/Heteroptera: Coreidae), likely a western conifer seed bug (Leptoglossus occidentalis). These often enter buildings in search of shelter, but do no harm there. See Leaf-footed bug detailed information .



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 


Larva of carpet beetle

7470.     Hello, We got a few bites this month, like giant mosquito bites but really itchy and large (and we don’t usually react to mosquitos). Checked our room for bedbugs but found no signs at all. But in the room next to us where our laudry piles up and next to a window that has holes in the screen, we found a few of these bugs. They do not seem to jump or fly and are maybe 1-3 millimeters in size. Please let us know! ETOBICOKE, Ontario. Canada


Number 7470.     This is a larva of carpet beetle (Coleoptera: Dermestidae) in the genus Anthrenus. It is very unlikely to be the cause of your bite symptoms. See carpet beetle control suggestions .


Grain mites

Hello. I’m seeking assistance in gathering information on grain mites. I have an infestation at my residence mainly in the kitchen. We have done everything from using the wood stove and a dehumidifier to lower the humidity. Countless cleanings. Removal of all food. We have been told we may need to dismantle the kitchen and remove the cabinets to remove any potential food source in the residence. Is this true ? Is there a product or treatment for this ? I believe it was caused by a grocery shopping trip to wallmart and an infected product may have been brought into the home. Please any information will be helpful. We have not been able to cook at home and eating out is extremely expensive in our location. Please any information would be helpful. Thanks

After taking the measures that you have already done, I am somewhat puzzled that you would still have an infestation problem. A complete dismantling of your kitchen should not be necessary. Are you absolutely certain that significant numbers of grain mites are still present? If so, you should be able to detect a distinct ‘minty’ odor. The only other suggestion that I have is that if you haven’t already done do, keep all of your unrefrigerated infestable food items in air-tight sealable containers.

Cloth moths

We had clothing moths – identified by pheromone traps. We have heat-treated textiles that can be heated and put in vacuum-sealed bags, and we are slowly working through freezing items that can’t be heat-treated. There are items where it’s not suitable for either. We have put them in vacuum-sealed bags. I believe that within a couple of weeks, it would suffocate any moths or larvae. My QUESTION is… will suffocation kill eggs? Toronto

Clothes moth eggs usually hatch in 3 to 10 days, so if the materials are kept vacuum sealed for at least three weeks, that should suffice. If the bags are transparent, you should be able to determine whether any living larvae are present. This article has some good control advice:

Grain beetles

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 .


Broad-nosed/short-snouted weevil

7468.    Trying to figure out what this bug is… flea? Kitchener Ontario. Canada
