Occasional Invader Control in Vancouver

✅ Fruit flies and house flies are among the most common pests under the “occasional invaders” As their name indicates, occasional invaders are a category of insects that appear in an indoor setting every once in a while. These insects include but are not limited to, sowbugs, pillbugs, centipedes, millipedes, moths, ladybugs and other garden beetle varieties. Flies appear more often indoors than other occasional invaders and are easily noticeable due to their high level of activity.

✅ Sowbugs and pillbugs are dark grey and measure around 1/4 to 3/4 of an inch in length. Sowbugs have a wider, more oval body shape with a skirt extending around the shell. Sowbugs feature a posterior two-part appendage that is not present in a pillbug. Pillbugs are more elongated and have the ability to roll into a ball.

✅ Millipedes and centipedes are reddish-brown to black in color. They vary notably in size, depending on species, but are generally observed to be a couple of inches or less in length. Millipedes have a thicker body with shorter antennae and two pairs of legs per body segment. In contrast, centipedes have a thinner body, longer antennae and one pair of elongated legs per body segment.

✅ Garden beetles and moths comprise a variety of species, such as ladybugs, ground beetles, European chafer beetles and gypsy moths, whereas flies comprise of house flies, mosquitoes, midges and numerous other species. Altogether, these insects range in color and patterning and while are generally small, do vary in size and shape.

Occasional invaders enter a residence through various openings along a building’s perimeter. Their small size allows them to easily move through cracks and crevices in the walls or floors leading from the outside.

Gaps along windows and doors are also typical entry points. Occasional invaders are attracted by shelter or a food source. Moths, in particular, are attracted to artificial light, whereas house flies will seek out potential food sources and breeding locations indoors.

Occasional invaders are not known to cause significant damage to a home or business. Beetles may feed on indoor plants or uncovered fruits. They may periodically excrete odour and leave stains on surfaces.

Occasional invaders are considered a nuisance that may become more problematic with larger populations.

Occasional invaders generally pose a low to moderate health risk. Centipedes are venomous and along with some beetles, are capable of biting humans. House flies may transmit dysentery, cholera and typhoid fever; mosquitoes, in particular, are associated with some deadly diseases and may present a greater health risk.

Typically, insect bites may cause symptoms such as pain, swelling, and redness, but are rarely severe. General symptoms vary depending on the size and type of insect, and if individuals are allergic to bites. Their presence and activity may also cause allergies to develop over time.
