What to Do After Pest Control Sprays

What exactly do you do after you have had a treatment done in your home? Would it be completely safe?

These are important questions that need to be asked the next time you decide to call Pest-Ex Pest Control Brisbane for an annual pest control treatment. Professional pest control companies would be more than willing to give you a detailed but brief explanation about how a treatment should be handled when the technician is done for the day.

Pest control treatments almost always include chemicals of some sort. What can you do that won’t affect the pesticide’s effectiveness? If you have youngsters at home or a pet, are there any safety precautions to know or do? Read on to see what the professionals have to say about such important inquiries.


Before having the pest control experts come over to your house, it is imperative that you mop the floors first. This will ensure a nice clean surface which will help bind the pesticide. Of course, improved adhesion increases the effectiveness of the treatment, ensuring long term pest prevention.

After treatment, it’s best not to mop as frequently if possible. The perimeter spray is designed to last approximately 30 to 90 days in terms of protection. You can still sweep or vacuum and keep the property clean, but preserving the perimeter-treated zone around the wall edges, skirting boards and kick boards for instance, is really important.

Thus, avoid mopping floors right up to the wall edge for the first six to eight weeks, because you want that invisible pesticide barrier to stay there for as long as possible, because any pest inside the house will be exposed to it.


When performing regular pest control treatments, for pests such as ants, cockroaches and spiders etc – pest control experts normally dust the weep-holes, the roof void, all cracks and crevices with a fine film or dust. Now, it’s common in the first week or two, to see a lot of activity (in terms of pests), coming out and dying.

Hence, it is common to see an influx of dying pests, especially if these areas like under fridges and behind dishwashers and under kitchen cupboards and cabinets were treated. If there’s a nest of a 100 of them in there, the pesticides will flush them out and there’ll be a lot of activity. But over time this activity will die down and get better.

Homeowners typically will find over the first two weeks, the population of pests will decrease down to 20% of what it is, and then over the following weeks after that, the last of them will all be affected by the gel bait and also the dust of which the pest control experts applied.


We always say, if you’ve got dogs or children in the house, it’s safer for them to be outside while we’re doing inside. It’s common for people to say, “Hey look, I’ll go for a walk with the dog” or go to the local park with their kids while we’re doing the treatment. It only usually takes 25 minutes for the product to dry. Once the product’s dry, it’s fine.
