In this article, I will be talking about the difference between the three major methods of pest control application and when each method is appropriate. Let's start with explaining the different methods of applying pesticides around your home. The three conventional methods are:
1. Hand spraying. This is done with a one gallon manual hand pump with a very limited flow.
2. Backpack spraying. This method is done by using a backpack. Backpack sprayers usually hold up to 4 gallons of pesticides and are usually, manually pressured with a hand pump. Flow is not as limited as a hand sprayer, but is still limited to less than 90 psi. We'll be coming back to why pressure is important a little later.
3. Power spraying. The method of power spraying is when the pesticide is applied by using a power pressurized pump that is usually mounted to the applicator's truck. The power spraying "rig" consists of a tank, generally 25-100 gallons, a pump (electric or gas powered) and a hose reel with 300 feet of hose, plus or minus. This method can have a pump that very easily applies anywhere from 100 to 300 psi.
Now that we've listed and explained the conventional methods to apply pesticides around your home, let's explain the pros and cons of each.
Hand spraying is the best method to apply pesticides inside of the home. It allows for precision spraying at low pressure so you do not over apply. This is where most companies use this method, but some companies choose this method to apply around the outside. With the very limited flow and low pressure, you are not able to get into any of the nesting sites that might be underneath boulders or in cracks and crevices. Services where this method is used are generally very low priced and are limited to applying a barrier in front of doors and on the inside. This is the least effective way to apply pesticides around the outside.
Backpack spraying is a step up from hand spraying. With this method, a technician is able to get into inaccessible areas with a decent amount of flow and pressure. With the flow and decent pressure of a backpack, this is an acceptable method to apply a barrier around the out side of the home but should not be used on the inside as it could cause for over applying. The major problem with backpack spraying is that it, like the hand sprayer, doesn't have the necessary pressure to get into the cracks and crevices (where insects and pests create nests) around your home. Services using this method are moderately priced and are ok for homes that have a limited bug problem.
Power spraying is best method available for applying around the outside of a home, in a "normal" non restricted situation. Power sprayers have good flow at high amounts of pressure. This allows for the applicator to get deep into cracks and crevices, flushing out nesting sites deep under ground or under rocks and boulders. With high pressure, applicators are also able to reach great heights to keep spiders from creating nests above your porches and patios. Large barriers around a home are easily applied with this method, which is very important when treating for scorpions, spiders and other predator pests. This method cannot be used inside homes as it delivers too much product and will be be hugely over applying. This is generally the most pricey method of pest control but is the definitely most effective method.
A good pest control company will have all of these methods available and know when to use each.
