Cockroach problem

My elderly friend has a cockroaches problem. Does lemon oil in water attract the roaches and kills them. I told her to dice an onion and sprinkle with soda to see if it kills roaches. Fredericton

I have seen no proven evidence that any essential oils (including lemon) are effective as cockroach control. Neither are onions. I suggest, visit the cockroach control section of the pestcontrolcanada.com web pages Cockroach Control Recommendations .

The basics can summed up as:

1. Clean your home well and often to get rid of the roaches’ food sources.

2. Seal cracks and crevices where cockroaches can enter your home.

3. Eliminate sources of excess moisture such as leaky pipes and taps.

Ground beetle

7332.        I have been seeing 2 or three of these tiny black bugs everyday in my basement bedroom for years now. I only seem to find them in one specific corner of the room and they stay on the floor or crawl onto my baseboard heater for the most part. They are very tiny and measure a little more than half a cm. I have tried identifying them with a pest identifier app but I’m not getting a match with any of the bugs on there. I apologize if my photos are not the best quality but I tried my best, it is hard to take a nice photo of such a tiny bug. I am from Manitoba and it is currently winter but I do also see them in them in my bedroom in the summertime. I do have another photo of three of these tiny bugs trapped in a piece of clear tape, that photo honestly almost shows more than the ones without the tape. But I did not upload them since it said do not upload photos of bugs in plastic. Please get back to me and have a great day thank you for your time:) Wawanesa, MB. Canada

 

Number 7332.     The beetle appears to be a ground beetle (Coleoptera; Carabidae). These often accidentally wander indoors, but are completely harmless and do not require any control measures. Ground beetle detailed information .   

Shrew-mouse problem

I live in a stack rock foundation home that is quite rural, with a dirt and bedrock crawl space. There is an open area beside the water heater with small openings to the crawl space below for pipes and wires. I saw a small grey ball of fur dash from there into the bathroom, I set up a mousetrap and soon killed a shrew. I have since been studying up on them, and have caught several more, as well as several mice. Further, something has either eaten on the spot, or pulled out of the mousetrap and removed, one dead mouse and one dead shrew before I could get to emptying the trap. This was on successive days, and then another entire mousetrap and dead shrew disappeared, but I could heard the sound of something trying to eat or remove it from where it had been dragged out of my sight behind the inaccessible water heater tank for hours that morning. My questions are these – why are shrews in my house – they eat bugs and mice. What is eating the dead animals from the traps? If there are shrews, which prey on mice, why are there mice? Thanks for your kind consideration – I have had a camera set up since the mousetrap was stolen, but nothing has stolen any dead animals since. I think whatever it is has had its fill. Please help with this mystery. Shelly, Ontario.

Shrews are carnivores, They will eat just about anything that they can overpower, including each other. I would not be surprised to find that shrews were responsible for at least some of the ‘missing’ trapped animals. As to what else might be involved, I hesitate to guess. In addition to the camera set-up, I suggest using white flour or a similar powdery substance dusted around the traps and on the floor in the vicinity of the water heater tank to see if an tracks appear that then may be identified.

Larvae of a scarlet malachite beetle

7331.          Hello! We recently renovated my old house completely. Tore down everything to the brick – new installations, new walls, new floors, windows, doors, everything. We barely have any furniture and most rooms are empty. Since we moved in a month and a half ago, I’ve been seeing this larva around the house. The first one was on the headboard of a new bed, so I thought it came from the bed, but then I started seeing it on walls and ceilings in other rooms. Most recently, I found one in the bathtub of the bathroom on the second floor, we only used the bathtub twice and don’t use that bathroom very much at all. It has all tiles in it. I can’t pinpoint where they are coming from because it’s always just one and in different rooms on both floors, usually on the wall or the ceiling. I did a lot of Googling and the closest I could find is a Malachite Beetle. Can you confirm if that is what it is? It appears reddish in color and it is very tiny. What could it be doing in my house? I also have booklice on walls, could it be eating that? I have seen about 15 of them in the past month, is this considered an infestation? The humidity in the house was very high at first, but it’s been at 30-40% for the past month. Please help me, I can’t find much information on it online, especially on how to get rid of it. I am pregnant and terrified it could take over our house 🙁 Thanks in advance! Požega, Croatia

 

Number 7331.  This indeed appear to be larvae of a scarlet malachite beetle, and as such, pose no threat of any kind. As they are predators on other small arthropods, it is possible they are feeding on booklice. There is no need for control. Larvae of a scarlet malachite beetle detailed information
