One thing that frustrates a lot of Baulkham Hills homeowners is paying for pest control and then still seeing bugs a week later. It’s one of the most common concerns we hear, and the honest answer is that it doesn’t always mean something went wrong.
Unlike the supermarket sprays that only kill what they touch, the professional-grade products we use work differently. Non-repellent treatments let pests walk through treated zones without detecting them, picking up the active ingredient and carrying it back to the nest or colony. That transfer effect is what actually eliminates the source, not just the individual insects you can see. The result is that pest activity can temporarily increase in the days following treatment before it drops off completely.
For cockroaches, this process typically takes 4 to 6 weeks for a full colony to be eliminated through the gel bait transfer mechanism. Ants generally clear up within 2 to 4 weeks. Spiders and silverfish tend to show very little activity after the first 1 to 2 weeks as the residual product works through treated surfaces.
We’ve put together a full breakdown of what to expect after each type of treatment, including exact timelines and when it’s actually worth calling us back under your warranty: What If I See a Pest After a Treatment?
Every treatment we carry out in Baulkham Hills includes a thorough inspection before we start. We use infrared cameras and moisture meters to identify pest activity in areas that aren’t visible to the naked eye, particularly for termites and rodents. You’ll know exactly what we found, what we treated, and what the follow-up plan looks like before we leave the property.
Our general pest control service covers cockroaches, ants, spiders, silverfish, and more, and it comes with a 6-month warranty as standard. If pests return within that period, so do we.
