Crazy weather for bugs!

Gotta love this heat!  STILL getting calls about spiders; pretty late in the season for that! Just realized something too – this is the first year in a while that we haven’t had any calls for either brown recluse or black widow spiders in Penetanguishene. That is most assuredly a good thing.

Anyway, carpenter ants seem to be slowing down now which is another good thing. They started early this year, so we did lots & lots of them all throughout Tiny, Tay, Muskoka and Simcoe.

And still only the one termite call – which has responded very well to treatment, thank goodness.

This heat can’t last TOO much longer though! Soon it will be time to book Ross to come out and refill/replace mouse baits, and/or to tackle any bat problems. Sure wish someone would call up for some bat houses sooner rather than later !! He’s left them sitting right where I planted morning glories; just happened to notice a few determined little flowers poking up from behind the blasted thing. THEY need to move!  Wouldn’t you like a nice seasoned bat house? I’m sure you would 🙂

If you are calling us this time of year, please do leave a message if need be and either Ross or I will get back to you as soon as we’re able…. my teaching schedule this semester is NOT ideal – have to drive down to Barrie 4 days each week for 2 or 3 hours each day. They can and will do better when I whine – but I save that for the Winter semester when I really REALLY don’t want to drive 2 hours for a 2 hour class every darn day. If I take what I’m given in the Fall semester, usually get what I want in Winter. Here’s hoping!   It does mean that I’m often not here to answer the phone right away though – but Ross will check & return messages if/when he stops in, and if he doesn’t, I will get to them as soon as I get home.

 

 

Black Widow Spiders

Black Widow Spider

Black widow spiders (Latrodectus mactans) is a highly venomous species of spider that is a native species to the United States. Canada and Mexico. The Northern Black Widow spider can be found in British Columbia, Alberta, Saskatchewan, Manitoba and Ontario. They are rare to find, but they generally like to hang out around trash piles, sheds, under rocks, wood piles, etc. Anyplace that is dark and a little damp is a great place for them to hide.

Female black widow spiders are known for their distinctive black and red colouring and their sometimes habit of eating the males after they mate. The mature female black widow spider is usually around 1.5 inches long and about .25 inches in diameter. They are shiny black with a red mark in the shape of an hourglass on the ventral (under)side of their abdomen, which is very round. The sizing of the female black widows can vary especially in egg-carrying or gravid females. The abdomen diameter in a gravid female can be more than 0.5 inches.

Mature male black widow spiders are very different in appearance to the females. Males are much smaller than females with their bodies at less than 1/4 inch. Their colouring is usually black but often they take have a similar appearance to that of juvenile black widow spiders. Juveniles have a distinctly different appearance then the females (and some males) in that their abdomens are greyish to black in colour with white stripes running across them spotted with orange or yellow.

Black Widows will typically prey on a variety of insects, but they will also sometimes feed on woodlice, diplopods, chilopods and even other aracnids. When their prey gets entangled in their web, the black widow will wrap the prey securely with web and then bite and envenom the prey. The venom takes up to 10 minutes to work and then digestive enzymes will be injected into the wound of the prey. After that the black widow will carry their prey back to their retreat where they will feed.

Despite being known as highly venomous spider, there is not much to worry about. In an article here Antonia Guidotti, an entomology technician at the Royal Ontario Museum, says while black widow sightings make headlines, Ontario is not exactly undergoing a scourge of the famed eight-legged arachnids.”The black widow is very rarely encountered. Most of us, even entomologists, haven’t seen a black widow in the wild in Ontario. Most of you are never going to see one. And the risk if you come across one is very small,” she assures.Guidotti says even if one should have the misfortune of encountering a black widow, the spiders present a much smaller danger that we’ve been led to believe.
