Paper wasp

7174.        Saw this the other day and could not find any info on this online. Hoping you can help indentify this little guy. MONCTON, NB. Canada

Number 7174. This is a paper wasp (Hymenoptera: Vespidae; subfamily Polistinae) in the genus Polistes; most likely P. fuscatus, the northern paper wasp – Paper Wasp Image  Usually not aggressive, they will defend their nest if it is disturbed. I have found their sting to be very painful, but the effects wear off quickly.

Dark-winged fungus gnats

7173.        Hi there. I have these little flies in my house. I have sprayed all my indoor plants with insecticides but that doesn’t seem to have helped so not sure what to do to get rid of them. any help greatly appreciated. Edmonton, Alberta. Canada

Number 7173. These look like dark-winged fungus gnats (Diptera: Sciaridae). They breed primarily in very wet/water-logged soil having a high organic content. The most effective control is to allow the soil in potted plants to dry out as much as practical between waterings. The flies are harmless nuisance pests, but their larvae sometimes can cause damage to very tender plant parts. Fungus Gnats Control Suggestions 

Nymph of an assassin bug

7172.        Found on pillow. Barrie, Ontario. Canada

Number 7172. This appears to be a nymph of an assassin bug known as a masked hunter (Reduvius personatus; Hemiptera/Heteroptera: Reduviidae), a cosmopolitan species often found indoors and reputed to have a very painful ‘bite’-  Masked Hunter Detailed Information 

Orb weaving spider

7171.        Seen crawling through long grass at the end of summer. Charlie Lake, BC. Canada

Number 7168. The image is too blurry for me to be certain, but it has the appearance of a rove beetle (Coleoptera: Staphylinidae). That being the case, it is very unlikely to have caused your symptoms. The only rove beetles known to cause any skin lesions are in the genus Paederus, and these are strikingly coloured, with alternating bands of black and orange – Click here for an example. Also, they need to be crushed against skin in order to cause any harm.

Use of Dragnet

Hello, I want to engage a pest control company to help treat my bug problems in the house. They plan to use Dragnet. Is this a safe product? Are there any risks to humans? I’ve been advised to stay out of the treated home for 5-6 hours after treatment. Is that sufficient? Thanks in advance. Vancouver

The active ingredient in Dragnet is permethrin, a synthetic pyrethroid. Toxicity to humans is relatively low with little risk of adverse effects from routine applications of the diluted product. Obviously, it would be wise to avoid exposure to large amounts of undiluted material, as cases of adverse effects have been attributed to acute massive exposure. According to the label, it is safe to come into contact with treated surfaces one the application has dried, but be aware that cats are far more sensitive than humans or dogs to permethrin. The half-life of Dragnet indoors reportedly is in the neighborhood of three weeks, so three months after application only about 1/20th to 1/15th of the active ingredient in the original application would remain. The label for Dragnet states “CAUTION”; this indicates a product that is of low to very low toxicity to humans – Click here for more information on Signal Words. I do not know of any pesticide that is completely risk-free to use.

Bumble bee

7162.        It is about 3/4″ long. Langley, BC. Canada

Number 7162. This is a bumble bee (Hymenoptera: Apidae; Bombus sp.), likely an overwintering queen. Because of its condition, I hesitate to make a specific identification, but Bombus melanopygus is a possibility; for detailed information Click here

Brown marmorated stink bug

7160.        Found inside of house on a window. Welland, Ontario. Canada

Number 7160. This is a brown marmorated stink bug, Halyomorpha halys (Hemiptera/Heteroptera: Pentatomidae).

Nymph of Indian Red Bug

7158.       These are numerous in this province, looking forward to know the ID of this organism. Kerala, India.

Number 7158. This appears to be a nymph of Probergrothius sanguinolens (Hemiptera/Heteroptera: Pyrrhocoridae), known as the Indian red bug – Click here for an image. They feed on a range of seeds and are particularly common on the seeds of plants in the mallow family (Malvaceae), especially those in the genus Sterculia (tropical chestnuts) and other. They also feed on freshly dead animal matter with early instar nymphs seeming to prefer animal matter to seeds.

Basement with silverfish and ‘centipedes’

Hello! I just moved into a basement apartment and the place is crawling with silverfish and centipedes. Any tips on getting rid of them, or preventing them? Natural or with pesticides. Ill try anything. Burlington

Basement with silverfish and ‘centipedes’ – I would like the client to provide images of the ‘centipedes,’ as I suspect that these more likely are millipedes (centipedes, being predators, seldom appear in large numbers in any one place, especially indoors). That aside, the Canadian government site Click Here has good advice for silverfish control. Millipedes require a moist environment in order to persist indoors, so moisture management/control combined with exclusion measures is the most effective treatment (admittedly, this may be difficult in a basement). Click here for more suggestions, bearing in mind the chemicals mentioned are registered in the USA, not Canada. However, one should be able to locate similar products in home/garden centers; check the label for active ingredients and types of pests it should cover.

Carpet beetle

7157.      Small bug found on clothing in closet. Very small, 4mm x 2mm size. Ajax, Ontario. Canada

Number 7156. This appears to be an engorged bed bug nymph. Click here for detailed information on these pests.

Little grey thing that looked like lint

I was sitting on my bed when i saw a little grey thing that looked like lint, then a few minutes went by and in the corner of my eye i saw it moving. a little clear worm with a black head was trying to get out of this grey cocoon. i’m pretty sure it was a clothes moth larvae because it looked the same and the cocoon looked the same. i checked all the clothing in the room, the curtains, the bedding and the mattress but not one thing that pointed to signs of clothes moths. could this have been brought in by one of my cats, (they are outside a lot) or am i looking at a possible infestation? what should i do? Saint John, New Brunswick.

Little grey thing that looked like lint: Another possibility is a household casebearer, Phereoeca uterella (Lepidoptera: Tineidae). They are in the same family as clothes moths, but usually do little damage as they appear to prefer chowing down on old spider webs and the like. They appear to be expanding their range northward, and have been reported from Nova Scotia and Prince Edward Island; Click Here

Suspected bird mite infestation

Suspected bird mites. Hi. I’m looking for a company that can help me with a suspected bird mite infestation. I was hoping for a company that does fogging? I’ve used a pest control company that has sprayed twice and also done a detailed inspection. They have not managed to see any sample but I feel them in my skin (digging, biting, crawling) and notice activity (ie I feel crawling or get bitten) around my bed, sofa and bathroom. In the weeks approaching the full moon when parasites tend to be more active, it even seems as if they swarm in certain areas and might be on the walls and other surfaces and then pull towards me as I pass by. I feel like spraying might not be getting to all of them. I’m hoping to get someone who can fog the home and maybe also get rid of some furniture like my cloth headboard, sofa etc. Any info or advice would be much appreciated. Thanks. Scarborough, ON

Suspected bird mite infestation: I cannot recommend any particular firm; the client can find listings of pest control professionals in his/her area at Click Here . (NOTE: From the client’s description of the problem, I would not be at all surprised if he/she were suffering from delusory parasitosis – the discomfort they experience is very real, but they are mistaken as to the actual cause; Click Here .

Checkered beetle

7155.        These little bad boys just showed up in the house, but I’ve also made a cat tee from driftwood. Caught maybe 6 in a couple weeks, but it is growing. I soaked the piece in my trucks bed lined with a tarp, filled with water borax and bleach for about 2 weeks, turned it over every couple days,and scrub the piece feverishly too. I cant imagine anythings living at that soaking with the ingredients, but, these showed up. Should I be worrying? VICTORIA, British Columbia. Canada

Number 7155. This is a checkered beetle (Coleoptera: Cleridae) in the genus Enoclerus, likely E. eximius, Checkered Beetle Image . Most of these are general predators on other insects; a few are scavengers, none are pests.
