Calgary pest season

What shows up when, what you can handle, and when to call.

## March to May

Melt opens grade and slab joints. Pavement ants use that water line. A spring perimeter spray without an exclusion list is a subscription until the next watering cycle. Follow the trail to the joint. [Ant control](https://www.frameworkpest.ca/pests/ants/).

## June to August

Wasps take soffits, meter boxes, and play structures. Remove the nest, then screen the void so July is not an annual invoice. Same-day only when it is over a door or play area. [Wasp nest removal](https://www.frameworkpest.ca/pests/wasps/).

## August to September

Mice test the envelope before hard cold. One mouse in September is a kitchen in January if the 6 mm gap stays open. That is the [mouse-proofing](https://www.frameworkpest.ca/mouse-proofing/) window. The service page is [mouse removal Calgary](https://www.frameworkpest.ca/pests/rodents/).

## October to February

Indoor rodents, pantry moths, and bed bugs after travel. Retail is honest when the tool matches the stage. A winter visit still closes joints. It is just a worse week to discover the garage door.

Typical visit $100–$1,500 + GST depending on severity, after inspection. [Ranges](https://www.frameworkpest.ca/cost/).
