Poison bait stations indoors.

4604  I have five poison bait stations for mice placed around the outside of the cottage. Should I bring any inside the cottage over the winter?

These are spotted (sometimes called pink-spotted) lady beetles, Coleomegilla maculata (Coleoptera: Coccinellidae), a […]

True fruit flies

5828  I found this in Hamilton Ontario on my front porch. I wouldn’t have looked twice at it, but from a distance it looked like a small scorpion.

ambush bugs

5827  Found these two in my yard in Brantford Ontario this past summer. Wondering what they are.  Scott. These are ambush bugs (Hemiptera/Heteroptera: Reduviidae; subfamily Phymatinae).
