Summer Pests

Spiders

Spiders

While Ontario is home to a large variety of arachnoids (spiders) the large majority do not pose health risks to humans.  The two most worrisome are the the Brown Recluse (at right) and the Black Widow.  Yes, that's right, the Black Widow is common to Ontario. 

The female Black Widow has a shiny black, globular abdomen with two yellow or red markings in a triangle shape. It looks like a hourglass. Males are smaller, lighter in color, with light streaks on the abdomen. The web is irregular, many times found along exterior foundations on slabs, under stones and rocks, behind shrubs . They will bite if provoked. The bite feels like a sharp pain ,like a needle puncture. After 15 minutes to an hour there will be muscular cramps. Bites are rarely fatal, but you should seek medical attention.

The Brown Recluse has a body that is yellow to dark brown and is usually 2 to 4 cm long. Combined with the legs it could be about 6 cm or longer in diameter .  The dorsal has a dark brown violin shaped marking, very distinctive. Their web is off white to Grey .  They can be found outside, under rocks, debris, wood piles, etc. ,but many times are found inside. They can be found in storage areas like closets, basements, attics, garages and cellars. Sometimes they can be around above the ceiling duct work or register. Many times people get bit by putting their hands or feet in something that has been in storage.  The initial bite is not intense, but poisonous. After 8-12 hours, the pain is more intense, and over the next few days large sores form leaving a disfiguring scar. You should seek immediate medical treatment after the bite.

It is highly recommended that you seek professional assistance from a NIMBYPest Management Professional when ridding yourself of these insects.

Earwigs are easily recognizable by their pincers (forceps harmless to humans) at the ends of their abdomen. They are dark reddish-brown, with light brown legs, and are about 5/8 inch long. 

In a season, females reproduce up to 20-60 eggs laid in burrows (called chambers), 2 to 3 inches beneath the soil. 

Most species have one generation a year, over-wintering in the soil. Both adults and the young require moisture to live.

Removing earwig habitats is very important to the control of all insects, including earwigs.

As they are attracted to lights, it might help to reduce some of the lighting outside at night.

Most insecticide treatment should be done outside with application around the building foundation, flower beds, mulch areas and turf within a couple of yards of the building, as well as in the crawl space areas of the home.

Call Nimby Pest Management for professional Earwig Control.

Flies

Flies

During the summer months 3 main types of flies are prevalent in Ontario: the house fly, fruit fly and cluster fly.  They will enter homes or other building via open doors, windows, cracks and broken screens.  The cluster and fruit fly will breed in decaying organic matter and will often proliferate indoors to become a serious pest problem.

Control of these pests is often difficult and annoying.  Call Nimby Pest Management for professional Control of house, fruit and cluster flies.

Sow Bugs / Pillbugs

Pillbugs (Armadillidium vulgare)are commonly found in home gardens across the Canada.  Also known as sowbugs (Porcellio scaber) pillbugs  will feed primarily on decaying matter and are important in the decomposition process. However, if present in large numbers, they have been known to feed on seedlings, new roots, lower leaves, and fruits or vegetables laying directly on the soil. This is where problems develop and a NIMBY Pest Management Professional may be required.

These small scavengers scurry when disturbed and are often found outside hiding under leaves, rocks, garden debris, mulch and other dark, damp areas. Occasionally they will enter homes as accidental invaders. Indoors they are usually just a nuisance as they cannot survive for more than a day or two without water.

Mosquitoes

Mosquitoes are most active during the early hours of the morning and early hours of the evening (usually right around dusk.)   While one or two bites over the course of an evening is quite common, the concern should arise when an individual is being bitten more than 5 times an hour.  This could be a good sign that a mosquito breeding ground is nearby.
