This is what I'm using for mights. You can get it at your hardware or Canadian Tire stores.
Permethrin
Permethrin, a pyrethroid insecticide, is a chlorinated, synthetic form of pyrethrum, an insecticide derived from chrysanthemum flowers. (Permethrin is longer acting than pyrethrum.) It has multiple uses, including head lice and scabies treatments, insect repellents, household insect foggers and sprays, tick and flea sprays for yards and pets, termite treatments, agricultural and livestock products, mosquito abatement, forestry and treatment of timber.

Signs of toxicity
Exposure to even small quantities of permethrin can cause severe and fatal poisoning in cats. Common clinical signs of toxicity include: muscle tremors, twitching, seizures (see the video clip, right), salivation, incoordination, fever and dilated pupils. After exposure to permethrin, signs of toxicity usually develop within a few hours but in some cases can take one to two days to become apparent. Diagnosis is made based on a known exposure to permethrin and clinical signs of poisoning.
How do cats become exposed to permethrin?
Sadly, cats are usually exposed to permethrin when pet owners inadvertently apply permethrin-containing flea spot-on products, which are made for dogs, to cats. These products usually come in a small pipette and the liquid is applied onto the skin on the back of the neck. The liquid is then absorbed through the skin and into the body.http://www.fabcats.org/owners/poisons/pemethrin/article.htmlAs Uno said "No Pest Insecticide Strip"
