Renfrew, Ontario Canada

Number 7069. This is a maggot of a muscoid fly, so there must be a food source somewhere in the vicinity. When these maggots complete their growth, they crawl away from their food source in search of a safe, dry place to undergo pupation.

Nymph of an assassin bug

7064.         Hello! I found this bug on a bedroom wall by the window, in a rural part of northern Nova Scotia. We had spent the day at Waterside Beach, and it’s possible this came from the beach home with us — though the house is also in a rural setting surrounded by fields and some trees. I’ve been told it’s possibly an assassin bug, maybe a kissing bug, and it could be a western conifer seed bug. I have children staying here and my main concern is safety. Many thanks in advance! Scotsburn, NS. Canada

Chicken mites

What is the most effective and still available product for killing mites in chickens in northwestern Alberta? Diatamaceous earth is not very effective. Wembley

Chicken mites: Control of mites on chickens is problematic to say the least, as there does not appear to be any treatment available that is approved for use in Canada. There are some ‘off label’ possibilities that might be considered; Click here for a detailed discussion.

Bed bugs

Can be bugs travel from one apartment to another via baseboards, electrical outlets, etc? Any info you can provide will be greatly appreciated. Thanks. Ottawa

Bed bugs: “Once bed bugs are introduced, they can crawl from room to room, or floor to floor via cracks and openings in walls, floors and ceilings.” Click here for details.

Elm seed bugs

We have elm seed bugs and I was wondering if there is something that would attract them when they are in the house? Something sweet? We have been spraying home defence around windows and doors but still find a few that are alive. Medicine Hat

Elm seed bugs: I am not aware of anything in a house that would be an attractant to elm seed bug. Simply vacuuming up any that get indoors should suffice; Click here for details.

Cockroaches

I bought A box of food into my house today then all of a suffdn my cupboard was full of cockroaches what do I do. London

Cockroaches: The box of food and the appearance of cockroaches could just be coincidental. That aside, control recommendations will depend on the species involved. Click here for details.

Squeaking sound

I went down to my basement today, I was down there day before last, and I noticed a squeaking sound (almost like a bird chirping) the lights were on and I couldn’t see anything out of the ordinary. I went back down about an hour later turned the lights on again, same thing noticed nothing but the sound. I decided to check again a half hour later but leave the lights off and same sound and I just turned my tv off to go up to bed and now I can hear the sound from the top of the stairs. So what would squeak for hours on end? Edmonton

Squeaking sound: Unless you can pinpoint the source, it likely will remain a mystery. Crickets excepted, the only home-infesting insects capable of making a sound audible to humans that I know of are the larvae of old house borers – Click here for details.

Spinosad in Canada

Hello, I would like to know if using elector psp is approved in Canada (spinosad). Amos

Bed bugs

I was bitten a couple of weeks ago and I have been spraying Ortho Bug be gone and vacuuming daily. I have also purchased a new mattress and box spring which I have kept the plastic on. I have been wiping the baseboards daily as well. I wash the bedding daily. The pest control inspector came in and looked at the baseboards behind my bed which I told him I had cleaned and he checked my headboard which has also been cleaned. That’s all he checked in my bedroom. He than checked the other bedroom my sister occupies doing the same thing. He informed me that there was no sign of bed bugs and had never been any. My question is could I have washed the evidence away. The bedding wasn’t even checked? Sudbury

Bed bugs: Based on your narrative, it would be extremely unlikely for you to have a bed bug infestation; there are many other possible causes for your bite symptoms, Click here for some possibilities.

Wasp Infestation

For the past two summers, we have noticed wasps going in and out of small holes in the mortar between the bricks at the front of our house. Last year, we sprayed several wasp control products into the holes. This past winter, we tried blocking the entry point with steel wool but this week, we have noticed wasps again going into the mortar in different spots. We want to get rid of them. Will the nest die off if we block entry and exit points with steel wool now or will that cause them to come through an interior wall? Is it a good idea to get pest control in to spray into the tiny holes or will they die off naturally over the winter.? Any advice is appreciated. Milton

Wasp Infestation: I would really like to see images of these wasps before going into any detail. The only situation I would find worrisome would be if they were yellow jackets, as then there would be the possibility of them gaining entry to voids behind the brick facing and constructing a large nest there. In the meantime, you could use a hand-held dust applicator to squirt an insecticide into the holes, Click Here for some examples.

Pesticide Importation

Hello, I’m trying to locate an definitive statement of what rodenticides and in what quantity I’m permitted to purchase in the USA and carry into Canada across the border. The products are commonly available at hardware stores such as Home Depot or online from Amazon.com. Most of the products that are available at hardware stores in Canada or Amazon.ca are useless. I would be purchasing the products from Amazon.com and having them delivered to a PO box in Blaine, WA. If you can help me with this, I would appreciate it. Thank you. Best regards, Daryl Morse. Coquitlam, BC

Pesticide Importation: You may be out of luck here –

Mouse entry

Hello!! I’m curious, we had a dead mouse in our laundry sink in the basement. I have never seen mouse droppings in our house other than behind the stove when we first moved in, 2 years ago, which has not made a re-appearance. I always keep an eye out for droppings since I am totally petrified of mice. We purchased a UV light to check for urine, and did not see any. Mind you, this was a 7$ UV flash light from home depot. Probably not the best, but still nothing. Our laundry sink drains into our sum-pump with the drain about half a foot from the ground or where the top of the water sits. maybe a little less. we have a basement window above the laundry sink and to the side which is basically completely sealed. I say basically, because it’s an old window and it wouldn’t surprise me if there was a tiny crack hardly visible. We keep a fitted piece of wood over the window well. any idea how this mouse came in? i’m assuming it was a baby since it was TINY. any suggestions or anything else i could look for? thank you. Brantford.

Mouse entry: Mice can get in through cracks as little as ¼” (about 5 mm). Also, do you have any cats? We live in the country, and occasionally, one our cats will bring a ‘present’ into the house.

Leaf cutter bee infestation

I have leaf cutter bees that nested in the styrofoam around my house. We covered up the nests and built a deck but the bees are persistent and want back in their nests. I was wondering what I can do to get rid of them so they start making nests in my new deck! Bracken.

Leaf cutter bee infestation: Leaf cutter bees are not known to cause serious damage to sound wood; if ready-made cavities are not available, they prefer to make tunnels in soft materials such as the pith of plant stems or rotten, punky wood. And in your case, Styrofoam. Styrofoam blocks sometimes are used in making commercial nests for leaf-cutter bees. Just be certain that it is indeed leaf-cutter and not carpenter bees that you have. If at all uncertain, submit photographs for identification. I have seen formulations containing bifenthrin (a synthetic pyrethroid) recommended as a repellent for leaf-cutting bees, but bifenthrin currently is not registered in Canada.

Nymph of a masked hunter

7056.         I found this guy walking slowly on the wall at night. Haven’t seen anything like this. From what I can gather online, it resembles a bit like a masked hunter. I’m wondering if his mottled appearance is due to cat litter. The picture is magnified as the bug is trapped under a shotglass and I zoomed in 4x with my phone. His real size is around nearly a cm I found him August 15th, 2020. Cheers. Toronto, Ontario. Canada

Yellow bear caterpillar

7055.         We have never seen this caterpillar around before and I have a garden so I’m outside all summer, weather permitting. It was first discovered on a sunny warm day on August 6th, 2020. I first saw one on my ornamental fig tree. I didn’t want to kill it so I put it in the grass. I saw what seemed to be a bigger one on the 9th in the vegetable garden near my finished cauliflower plants. I have no idea where it went from there. I showed the picture to my local nursery and they didn’t know what it was. I don’t want to hurt it but I also don’t want predators in my gardens. Surrey, BC. Canada

Number 7054. This looks like a yellow bear caterpillar (Spilosoma virginica; Lepidoptera: Erebidae); the adult is known as the virgin tiger moth. The white objects are not eggs, but the cocoons of a parasitic wasp in the family Braconidae. When the larvae have finished feeding on the innards of the caterpillar, they chew through the caterpillar’s skin, spin a cocoon and undergo pupation.

Scuttle fly

7053.         These keep crawling out from behind the overhead fan above my stove. At first I thought they were flies but then I realized it doesn’t look to have wings. Then I thought it might be a roach but it doesn’t seem to have antenna. It’s summer time and very hot in the apartment. It kind of looks like a scuttle fly but why doesn’t it have wings? Thanks for your help! Vancouver, BC. Canadaa

Number 7053. This does look like a scuttle fly (Diptera Phoridae); Click here for an image. In addition to some species having wings so transparent as to be nearly invisible, some other phorids are completely wingless.
