WASP NEST IN ROOF. Sorry long message A few months ago end of July early August I noticed wasps getting into a space under my roof I told my landlord thinking he’d get a professional to see to it but nope he only plugged it up him self before making sure their was no nest and way would they be dead now and if not what do I do I am hearing like a humming/buzzing in my ceiling going from one end of my trailer to the other I also had a bees nest in my crawl space under my trailer that he sprayed and I haven’t seen any since I was stung a few times by a wasp and also by a carpenter bee I just noticed the buzzing wen everyone got quite I haven’t been home all day so I am not sure wen it started but is the humming or buzzing I hear wasps if so how do I get ride of them I feel like my landlord just put a quick fix on the problem without actually getting to the base of the problem. Summerside, Prince Edward Island


Wasp infestation in trailer ceiling – First, make sure that the buzzing sound is coming from insects and not some other source, such as an electrical problem. If it is indeed coming from wasps, with your landlord’s permission, make an opening into the space above the ceiling from the outside of the trailer large enough to insert a nozzle from an aerosol spray (preferably a synthetic pyrethroid) labeled for homeowner use (check label for any fire hazard warning – if none, spray out the contents and seal up the opening). If the buzzing persists after this or if you cannot get permission to apply the spray, you may have to let cold winter weather take care of the job. Normally, only the queen survives the winter, and if she remains sealed up in that space, she will be unable to establish a new colony. Just be sure that you go over the trailer very carefully to be certain that any potential entry places have been covered/sealed.


Bird mites

I’ve had a terrible rat mite problem for 3 years. I’ve lost access to my bedroom and my study room. I’ve had pest control come in to leave rat traps and spray for rat mites. I haven’t seen a rat in over 2 years, but after 3 months of pest control spray, the mites keep returning. What am I doing wrong? Why do the rat mites keep returning? Toronto


If rats have indeed been eliminated from your premises, your problem may not be rat mites, as these cannot complete their life cycle on humans alone. I suggest inspecting the exterior of the home and immediate surroundings for bird nests. Bird mites often are mistaken for rat mites, and like rat mites, these will invade homes and feed on humans in the absence of their usual hosts.


Cluster Flies

I live in LaPeche, Qc. My south facing outside wall is covered with Cluster flies and they are starting to come in through the basement windows. How do I get rid of them? They are all over the walls and I can’t reach those high on the walls. Is there a kind of insecticide powder I can put along the bottom of the walls and balcony?


Click here for a Government of Canada pub on their control. Any flies that gain entry can be knocked down with an aerosol spray and vacuumed up.


Bed Bugs

Hello! This will be a little long but I’m hoping someone could help. Two weeks ago my niece and brother in law were visiting and they stayed over night two nights she brought a backpack but it was only in the house for 10 mins ish like twice and they slept on our couch. Well apparently they have bed bugs and now I’m concerned we have them as well as soon as they left I vacuumed my couch and took all the cushions off and I have been doing this every few days since then I have not saw any bugs or any casings/ blood stains/ poop on the couch could it be too soon to notice any thing or are we out of the woods at this point?? Please help!! Hamilton


Bed Bugs: It is indeed too soon to tell whether or not you have uninvited guests, and you appear to have taken reasonable precautions. I suggest that you peruse the following document on bed bugs, about the best I’ve seen on the subject: Click here 


Flea control

I have a dog, I flea treated him but my room mate had cats that she did not treat. The infestation is bad. The room mate has since left with the cats, but my house is still infested. I never had this problem before until her cats arrived. I’m overwhelmed and don’t know what to do. Also do not own a working vacuum. Hamilton, Ontario


You should consult with a licensed veterinarian for specific advice. Click here This site has some general recommendations that may be helpful.   I also highly recommend you obtain a good vacuum cleaner. 


Springtail control

Hi, Can you guys suggest an insecticide to get rid of springtails. I’ve had my home sprayed three times but with limited success. My home is not damp and is very clean. John H. CBS, Nefoundland


Chemical applications (usually pyrethroids) generally are not recommended for springtail control, as the effect is only temporary and applications usually must be repeated. Click here for some detailed suggestions. As you state that your home is not damp, there may be something else going on other than springtails, as they do require moist conditions in order to thrive.


Cockroach control

Hello, I hope you are well. I would like to know if cockroach spray/dust is safe for infants. I live in an apartment and they are spraying to get rid of cockroaches. I have a 1 month infant. They have said that we need to leave the apartment for 4 hours after they spray. I would like to know if it is safe for my infant to re-enter the apartment after 4 hours. Please let me know. Thanks. Mississauga, Ontario


It depends on the specific pesticide being applied. If it is a synthetic pyrethroid (commonly used in cockroach control), it probably would be prudent to wait a bit longer than four hours. A Canadian government web page on pesticide safety recommends waiting 12 hours unless specified otherwise on the pesticide label – Click here

Pharaoh ants

We have hundreds of tiny red ants coming out of a heat vent and baseboards. What can we use to get rid of them? Grande Prairie AB.


As you likely already know, ant control methods can be species-specific; what works well against one species may be completely ineffective against another one. That aside, if the ants are indeed tiny (less than 2 mm long), they may be Pharaoh ants, a species notoriously difficult to control. Click here for some advice 

Potato beetle control

We had a terrible infestation of potato bugs this year but could not find a product that would irradiate them. It seems the old products we used to buy are no longer available. Please tell me the name of a product that will work that I can buy for next year. East Selkirk.


Potato beetle control – I have had good success using a formulation containing Bacillus thuringiensis var. tenebrionis (Bt-t) bacteria. This targets the young larvae, so it should be applied every few days as soon as the eggs start to hatch. If you apply it too early, the bacteria won’t survive until the larvae emerge, so the treatment won’t work. Also, Bt-t is sensitive to UV rays, so you should spray late in the evening or on cloudy days. Also make sure that it won’t rain within 8 hours after you have sprayed. You can tell if the treatment is working because the larvae will turn black.


Cockroaches in potted plants

I have a pretty bad cockroach infestation and I am in the midst of carefully moving all of my things out of my apartment but I have concerns about my plants. I have bleached their pots, hosed down the plants including the roots, and repotted them. I just bought the diatomaceous earth to put down. I was wondering if there is anything else I can do. And if this is everything, how long do you think I should wait before I can safely bring them to the new apartment (they are outside of a friend’s house at the moment). Do you think they are safe right now? I’ve always kept them super dry in an effort to make them unappealing to fungus gnats, so I doubt they were appealing to begin with, but I am so concerned. Thank you so much. Montreal.


Cockroaches in potted plants – From the sound of what you already have done, the only additional step I can suggest is to make a visual examination of each pot (especially the bottom) as you pick it up to ensure there are no hitchhikers.

Importing Rodent Poison

“Importing Rodent Poison”. Can I bring mouse bait “RESOLVE” or “BAIT BLOCK”from the U.S. in to Canada?
The active ingredient is Diphacinone 0.005%. Thank you. Jacquie Aird. Vancouver, B.C., Canada


Importing pesticides into Canada: Residents of Canada may purchase and import, from the United States and only for their own use, products registered with a NAFTA label. You may transport the product on your own, work together with a group of growers with a designated driver, or hire a customs broker or carrier. (Click Here)

All pesticides imported into Canada must meet Canadian standards, i.e., be registered or scheduled under the Pest Control Products Act (PCPA), and bear the Canadian label. (Click here)

Starting April 18, 2018, you can no longer bring unregistered pesticides into Canada if they are not equivalent to those already registered in Canada for personal use in or around your home (i.e., Domestic Class products). An equivalent pesticide is one that has the same active ingredient in the same concentration.

In addition, you will no longer be allowed to purchase unregistered pesticides online and have them shipped to Canada. The purchaser of the product must bring it into Canada in person. (Click here)

Japanese beetles

Japanese beetles. These beetles are absolutely destroying our roses, hibiscus, hydrangea and red maple. I am so very upset. We have the traps and have sprayed what is best in their management? should I have the lawn treated for larvae and if so what time of year. Thank you. Jill. Welland Ontario.


As far as Japanese beetle control is concerned, I do not recommend traps unless your property is large enough so that you can place the traps far away from any vegetation that you want to protect (or better yet, persuade your neighbours to put some on their property!).

There are several formulations effective against the grubs (milky spore – a fungus, BTI – a bacterium, and nematodes), but these will only work on the area where applied; there is nothing to prevent adult beetles emerging from untreated areas near you to invade your property.

German cockroaches

Do you know how or where I can purchase insect growth regulator in Canada. My son has purchased a house that ended up having German roaches. We have contacted a local exterminator who for $1000.00 will take care of the problem but only guaranteed for 45 days. Sounds like they will kill everything alive but the next generation. Regina.


I have found these IGRs recommended for German cockroaches:

Gentrol Point Source (Zoecon) – (this can be shipped to Canada)

Vendetta Plus Cockroach Gel Bait (4tubes) Roach Bait & I GR Roach Killer Paste – (I do not know if this can be shipped to Canada)

In the event that you cannot obtain an IGR labeled for homeowner use, you might try this bait formulation which is supposed to remain effective for up to a year – Click here or this one – Click here

Cockroach infestation

Hello, Is there anyway to control a cockroach infestation in canada? It seems like there are no bait stations or boric acid dusts available in Canada. Thanks, Andrew. Saskatoon, SK.


Cockroaches are always difficult to control. Strategies to control vary depending if it is an multi unit building or an individual house. 

There are boric acid dusts available but because of insect resistance and bait shyness they are not very effective. A multi prong approach is usually used composed of both chemical (baits and sprays) and non chemical control (heat, vacuuming, sticky insect traps, etc). 

Good sanitation is key as cockroaches thrive in unclean environment. Kitchen grease and food crumbs behind stoves and fridges can provide food for long period of time. 

It is always best to contact a pest control professional, who should work with the property management to work out a good solution. 

Black wasps

For 3 years in a row we have been finding black wasps in our house. Every summer 3 – 5 slowly come out of who knows where. Then we don’t see them again until the following year. Lucky my cats find them before my kids do.
The question is how do I find where they are coming from? Why do they keep coming back? Tecumseh


Wasps build new nests every year. The likelihood of new nests close to previous nests is high as the wasps go to where they think it’s a safe place to build. Seeing other nests in the vicinity makes that decision easier. 

I would suggest doing a walk through along the external perimeter of the house on a nice sunny day and observe where the wasps are entering the house. They need to access a void in order to build. Once located please contact a professional to treat. 

The wasps you’re seeing are probably ones that have lost their way heading out of the nest and then ending up on the inside. They will normally be slow moving as they have depleted their energy and gather by the windows, following the light in order to get out. 

Vacuum them off as spraying is a waste and detrimental to ones health on the inside. 

Spiders and pill bugs

Hi there, we have a lot of shrubbery in the yard and experience a lot of spiders as well as pull bugs. We experience spiders inside the house as well. Looking for a suggestion and quote. Thank you. Surrey BC.

Spider population build up over time, especially if no control measures are taken around houses. A high spider population also tells one that there is a large insect population as spiders feed on insects.
Recommend using a permethrin based spray around the external perimeter of the house and along the window frames and along the eaves.

On the inside of the house, I would suggest insect sticky or monitoring boards at various locations all over the house along the baseboards. The boards should be replaced every week until the population is under control.

Spraying along the inside of house ONLY if the infestation is really heavy.

Pill bugs feed on decaying vegetation especially around the external perimeter of the house where grass clippings and other vegetations tends to collect. Once this population builds up, pill or sow bugs then tend to enter the house through cracks and crevices. Although they do not pose much of a health hazard – they are considered a nuisance.

The external perimeter spraying with a permethrin based insecticide will help bring down the sow bug population. In the inside of the house – use of only insect sticky boards to control the sow bugs.
The insect sticky boards will be effective for both the spiders and sow bugs.

Bed bug

Bedbug query

I have been cleaning a friends apartment and discover after several visits in and out, that his place is infested with bed bugs? My concern is did I bring them home on my cloths? I didn’t sit down on any anything but I did remove his bed sheets etc because they were soiled. What should I do?

The bedbug query – Unless you physically removed some of the items from the infested premises and placed them in your vehicle or took them home with you, there is very little risk that you inadvertently brought bed bugs into your home. If you did take the soiled bed sheets home with you and they were not immediately laundered, you need to be on the lookout for signs of infestation.
