This page shows what it says and which of our services fits each problem.
| Pest | What the local sources say | Our service page |
|---|---|---|
| Mice and rats | A dwelling must be kept free of rodents, vermin and insects at all times, and extermination methods must follow the Pesticides Act. | Mice exterminator Markham |
| Bed bugs and cockroaches | The Landlord and Tenant Board says a landlord must take steps to control pests such as cockroaches and mice and meet the standards set out in municipal by-laws. | Bed bugs · Cockroaches |
| Mosquitoes | York Region sets 34 mosquito traps across the region once a week from mid-June until the end of September and tests the captured mosquitoes for West Nile virus. York larvicides catch basins and standing water on public property, and catch basins on private property can be treated at no charge once a season with long lasting briquettes, by calling Health Connection at 1-800-361-5653. | Mosquito control Markham |
| Ticks and fleas | York says the risk of getting Lyme disease from a tick bite increases with the time a tick is attached and usually requires the tick to be attached for 24 hours or more. | Flea and tick control Markham |
| Wasps | Health Canada advises leaving a non-hazardous nest until November or December and using a professional for removal. | Wasp removal Markham |
| Ants, spiders, silverfish | No local counts are published for these. Recorded sightings and Markham's climate normals shape the timing. | Ants · Spiders · Silverfish |

The chain is simple: light attracts insects, insects become prey, and spiders position themselves where the hunting is good. If the same window or light fixture keeps producing webs, it's telling you that location consistently produces insects, not that the spider has any particular interest in your siding or trim.
