Fall and Winter Pest Threats


crickets in the house, cricket exterminationCrickets occasionally invade homes and become a real pest. They are harmless, but the monotonous chirping sound they make can be so loud that it will keep you up all night. The sound is created by running the top of one wing along the teeth at the bottom of the other wing. Heavy cricket migrations are hard to control. It may be necessary to use insecticides both inside and outside the home. More information on cricket control »


house spider control, spider exterminationSpiders are one of the most feared home invaders. There are more phobias about spiders than any other pest, and understandably so. If you get bitten by the wrong spider - a black widow or a brown recluse - and you have a bad reaction to the venom, you can end up in the hospital. More information on spider control »


rat control, rat exterminationThe Norwegian rat, also known as the brown rat, common rat, sewer rat, or wharf rat first came to America on-board Colonial sailing vessels. Norwegian rats now occupy every major city in the US and Canada. During fall and spring they begin to reproduce and at the same time they start coming indoors. A single female brown rat can give birth to more than forty young in one year. The rats enter through holes they either find or create.

When treating for rats it all begins with exclusion. We will treat any rat holes with tracking powder and set bait boxes. Under certain conditions we will attempt to live trap the rats. Live trapping can catch rats in one night and you don't have to worry about them dying behind walls. Nothing smells worst then a dead rat! The disadvantage to rat trapping is you seldom catch them all, so combining exclusion with rodenticides and trapping is necessary.More information on rat control »


cockroach control, cockroach exterminationAny time is a good time for roaches. These guys know no season. The thing that makes roaches so difficult to control is their truly inspiring reproductive rates. A female German cockroach has approximately 30 young every 30 days. Additionally, female roaches can store sperm from just one mating and use it for the rest of their lives.

Breaking the cockroach's breed cycle is key to controlling this insect. Roaches require an integrated approach. We will often spray fog and use baits. We also use something called an Insect Growth Regulator (IGR). Young roaches growing up in an environment filled with IGRs will not be able to reproduce. IGRs typically take longer to work (usually 6 to 8 weeks) but over the long haul they work the best. More information on cockroaches »
