FAQ

What surfaces can I use CritterKill on?

CritterKill is suitable for treating most hard, non-porous surfaces like mattresses, box springs, wooden furniture, plastic, metal, and fabric. Avoid spraying directly onto delicate fabrics without testing in an inconspicuous area first.

How often should I reapply the spray?

For initial treatment, apply the spray every 24 hours for the first week. Afterwards, a follow-up application every 7-10 days is recommended to ensure any newly hatched bed bugs are eliminated.

Does CritterKill kill bed bug eggs?

Yes, the formula includes ingredients designed to break down and destroy bed bug eggs on contact. However, for optimal results, thorough treatment of all infested areas is essential.

What size area does one bottle cover?

One 250ml bottle of CritterKill spray covers approximately 30 square metres when used as directed. Always read the label for precise application guidelines and surface coverage recommendations.

How do I apply the powder?

The CritterKill powder is designed to be sprinkled directly onto areas where bed bugs hide, such as seams of mattresses, cracks in furniture, and under baseboards. Work the powder into the affected area with a brush for best results.

Is CritterKill safe for children and pets?

CritterKill is formulated to be relatively safe when used as directed; however, it's important to keep children and pets away from treated areas until they are completely dry. Always store out of reach of children and pets.

What if I still see bed bugs after using CritterKill?

If you’re continuing to notice bed bugs after treatment, it could indicate a more extensive infestation requiring professional pest control services. Thoroughly inspect all potential hiding places and repeat the application as directed.

How long does it take to see results?

You should typically start seeing an immediate reduction in adult bed bug activity within 24-48 hours of initial treatment. Complete eradication may take several weeks with consistent application and follow-up treatments.

Does CritterKill have a strong odour?

CritterKill is formulated to dry quickly and leave minimal odour, however, some users may notice a slight chemical smell initially. This dissipates rapidly once the product has fully dried.

What’s included in the CritterKill Bed Bug Control Kit?

The kit contains one 250ml spray bottle, one 125g powder application tube, and a detailed instruction manual outlining the complete treatment process for bed bugs. Refer to the manual for specific application techniques.
