Have you noticed in influx of spiders inside lately?  Well for some species of spider, mating season is here and will continue through October.  Spiders come inside our homes for various reasons:

  • To find a mate
  • To find food
  • Open cracks & crevices

Weather stripping, sealing up cracks and crevices & keeping windows and door adequately screened/shut will go a long way to reduce your in home spider population.  Of course, if the spiders are particularly bothersome or plentiful or you just don’t want them in the house- we do recommend a spider treatment.  Now is a great time to treat for spiders, before they mate & multiply and before they lay eggs and leave lovely little packages of eggs that will be baby spiders ready to come out in spring.

If spiders are coming in for food, reducing their food supply (insects) will also reduce their numbers.  When it comes to spiders in homes, starving them out would be pretty effective.  Unfortunately it’s also kind of impossible (in most places).  However, there are steps you can take to lower the population of spidery snacks.  Vacuuming regularly, rotating and cleaning behind and under furniture, getting rid of clutter especially the kind that just sits in a closet, basement or garage will be helpful.  If you live in an area prone to spiders, or have a particular aversion to their eight legged creepiness, a preventative spider treatment will go a much longer way as far as reducing the number of panic evoking sightings.

Inadequate weatherproofing is an open invitation to spiders and all kinds of insects.  They’re not to keen on seeing walls as a signal to keep out.  As long as there is a crack big enough for them it’s like you’ve put up a free rent sign and invited them in.  While it isn’t reasonable to think you can shore up ever single entry point, in many homes there are some pretty simple ways to reduce your indoor bug population:

  • Make sure you have fitted screens for each window (and door)
  • Maintain your screens, patch holes and replace screens that no longer fit tightly in place
  • Caulking foundation cracks (if there are major cracks, call a contractor for an estimate on repairs)
  • Turn off lights that are not being used (even outdoor lights as they attract some bugs)
  • Put up tiny “No Trespassing” signs (this step may or may not be completely useless)
  • In areas prone to bugs set up a monthly, quarterly or other interval general pest maintenance with Peak Pest Management

Most spiders only live about 1 year (give or take depending on the species), although some species of tarantula can live upwards of 25 years.  So treating your home for spiders twice a year, during mating season and then again in Spring when the newly hatched spiders are striking out on their own for the first time seems to be a pretty effective interval for most homes here in the northwest.
