Pest Control FAQs, answered by experts

The last thing you want is to fend off a swarm while on top of a fully-extended ladder. Additionally, be extremely careful when using a ladder, as falling from a tall height can result in serious injury. 

Leaving things to a pest control service in your area could be the best course of action if the nest is in an enclosed or difficult-to-reach space. If your spray doesn’t hit the right spot, is too far away, or isn’t powerful enough, you risk aggravating rather than killing all the wasps.

It’s not fast, but you can tightly seal items and store them away for at least a few months, preferably an entire year. Bed bugs can’t survive that long without eating. However, this method takes significantly longer than other common eradication methods like heat treatments, steaming, or fumigation, so it’s not a first choice for homeowners.

If the snakes in your yard are non-venomous species (like common Rat or Garter snakes), why not consider the live-and-let-live approach? Some benefits of not getting rid of snakes include:

  • They’re great at controlling disease-spreading rodent populations, including rats, mice, voles, and moles.

  • Some non-venomous species (like the common kingsnake) eat venomous species like rattlesnakes and copperheads.

  • Species like the garter snake keep down populations of garden pests like slugs and grasshoppers.

Bed bugs are highly sensitive to heat, so a hot blast with a hairdryer can draw them out of hiding. Providing a source of warmth, such as a heating pad or hot-water bottle, can attract and lure them out. Bed bug monitors and traps with pheromones can also be effective.

It’s an age-old and terrifying question: Can rats come through the toilet? The answer, unfortunately, is yes; however, it’s extremely rare. In the very unlikely case that this happens, it’s usually the result of rats from the sewer making their way into home plumbing pipes and up into the toilet.
