Mr. Pest Control


Q:

What advice do you have for flies in and around horse stables?

A:

Much of fly control in horse stables is out of a PMP’s hands because a lot depends on how well stables manage feed, bedding, and manure. Stable flies breed in manure and house flies breed in other moist organize material. Flies reproduce so quickly that they become highly resistant to pesticides, so a stable’s debris management is the most important factor in fly control. Instead of telling you what a stable should be doing, I’ll tell you what your other options are:

  • Baited fly traps
  • Fly baits
  • Insect light traps
  • Residual pesticide treatments

Baited fly traps and fly baits will only be attractive to house flies because stable flies are blood feeders. Insect light traps will attract both house and stable flies. They should be installed inside a stable and not visible from outside. Residual pesticide treatments can be effective for both house and stable flies as well, IF they are applied to fly resting sites, which are marked by fecal specks. Flies often rest on fences or overheads in stables.

Q:

What is your best recommendation for a scorpion treatment inside a residence?

A:

Indoor treatments for scorpions should be targeted to voids, like wall voids and attics. Those are the areas in a structure they tend to inhabit, so focus on the walls in the house where scorpions are seen the most. Scorpions in light fixtures point to the attic being a problem. Dusts are the best formulation to use in voids, although aerosols and space treatments can also work. Hiding places in living areas like closets and underneath furniture can be spot treated with a residual, but this should not be the basis of an indoor program. These are also good places to put glue boards for trapping and monitoring.
