Regular monitoring and maintenance of the traps ensure they remain efficient over time.


Barriers act as a physical deterrent, preventing pests from accessing certain areas of your home. These can range from simple solutions like screens on windows and doors to prevent flying insects from entering, to more specialized options like copper mesh around the base of plants, deterring slugs and snails. For larger pests, such as rodents, sealing cracks and openings in walls and foundations with steel wool or caulking can block their entry paths. Installing barriers is a proactive measure that helps reduce the need for intervention later.

Heat and Cold Treatments

Extreme temperatures, both hot and cold, can be used to eliminate pests effectively. Bed bugs, for instance, are highly susceptible to heat treatments. Professional exterminators use specialized equipment to raise the temperature in an infested area to a level that is lethal to bed bugs but safe for your home. On the other end of the spectrum, cold treatments involving liquid nitrogen can freeze and kill pests like cockroaches and bed bugs. These treatments require professional application to ensure safety and efficacy.

Manual Removal

Manual removal involves the direct extraction of pests from your home. This method is typically used for larger invaders, such as rodents or even stray wildlife finding their way indoors. Using gloves and other protective gear, pests can be captured and relocated. For insects like spiders or individual wasps, vacuuming is an effective and immediate removal technique. Although manual removal can be labor-intensive, it offers a non-toxic, straightforward solution for visible pests.

By understanding these physical pest control methods, you’re better prepared to tackle unwanted guests in your home. Remember, combining these techniques often yields the best results, keeping your living space pest-free in an environmentally responsible way.
