Is it safe to seal the hole where wasps are going into my wall?
Sealing is the last step, never the first. An Alexandria provider dusts the void, leaves it open so returning foragers carry the product inside, and comes back to confirm the colony is dead. Once it is quiet, the Alexandria entry gets sealed so next year's queen cannot use it.
How long does wasp nest removal take?
The treatment is quick; the dying takes longer. Aerosol on an exposed comb at an Alexandria home works within minutes, while dust in a void kills over several days as workers track it through the nest. Expect your Alexandria provider to say the colony is finished only after a follow-up check.
Can wasps damage my house?
Mostly indirectly, but yes. A large yellowjacket colony inside an Alexandria wall can stain and soften drywall as the nest grows, and trapped wasps chew through ceilings and around fixtures. Hornets also strip thin layers of wood from fences and decks at Alexandria homes to make nest paper.
Are wasps dangerous to my pets?
They can be. Dogs and cats investigate ground nests with their noses, which is exactly where an Alexandria yellowjacket colony will sting first. Swelling of the muzzle or throat can affect breathing, so a pet stung several times at an Alexandria home should be seen by a vet.
Should I be worried about a nest in the ground?
A ground nest deserves respect. The entrance hole in an Alexandria lawn looks small, but the cavity beneath, often an old rodent burrow, can hold thousands of workers. Treatment is a dusting of the entrance at dusk, which any Alexandria provider can do quickly, followed by a check that traffic has stopped.
What stops people from dealing with wasp nests?
Mostly not knowing how. The same question comes up in Alexandria: not knowing what to do stops more people than money, based on the 26% of New Zealand respondents citing knowledge as their barrier in the Moths and Butterflies of New Zealand Trust's 2025 survey, an overseas attitude figure that argues for learning the basics early. If you are in Alexandria, use this as a starting point for questions rather than a prediction for your home.
How many people use bait to control wasps?
Alexandria is not an outlier on this point: in the Moths and Butterflies of New Zealand Trust's mid-2025 survey of 1,055 individuals and 100 restoration groups, 13% of all respondents reported using Vespex bait, far behind nest destruction at 43% and traps at 23%; the unweighted results are specific to New Zealand. For a property in Alexandria, the next step is an inspection that identifies the source, not a guess based on national averages.
